Joy added 26 new contacts to her phone list. She now has a total of 100 contacts. Let c represent how many contacts joy had on her phone before she updated it
Answer:
c=74
Step-by-step explanation:
Let c represent how many contacts Joy had on her phone before she updated it.
Because Joy added 26 new contacts, we can say that c+26 is equal to her new total of 100 contacts.
c+26=100
Therefore, the equation that represents this situation is c+26=100
Now, we can use our equation to solve for c.
c+26=100
Subtract both sides by 26 to isolate c
c+26-26=100-26
c=74
Therefore, Joy had 74 contacts on her phone before she updated it.
I hope this helps!

Can you help me from 1 to 8 and tell me how you get the answers for each one of them please
Answer:
See below.
Step-by-step explanation:
1) 4x + 8 = 2x + 10
2x = 2
x = 1
2) 9y - 3 = 6y + 12
3y = 15
y = 5
3) 8m + 4 = 4m - 20
4m = -24
m = -6
4) 11z - 14 = 5z + 4
6z = 18
z = 3
5) 3q - 6 = 8q - 6
5q = 0
q = 0
6) 20n + 7 = 6n - 21
14n = -28
n = -2
7) 2w - 8 = 7w - 3
5w = -5
w = -1
8) 9k + 4 = k - 12
8k = -16
k = -2

9 added to twice a number is the same as 27 reduced by 4 times the number
Answer:
x = 12
Step-by-step explanation:
Let the number be x.
9 added to twice a number is the same as 27 reduced by 4 times the number
If we add 9 to the number = (9+x)
If 27 reduced by 4 times the number = (4x-27)
ATQ,
(9+x) = (4x-27)
Taking like terms together,
x-4x = -27-9
-3x = -36
x = 12
Hence, the number be 12.
Tell whether the relation is a function.
Answer:
No, it is not a function
Step-by-step explanation:
Here, we want to tell if the relation is a function
For the relation to be a function, each independent variable must be mapped to only a single dependent variable
So what this means is that one term of the independent side must be mapped to one term of the dependent side
From the question, we can see that -10 and -15 were both mapped to -10 which should not be so
This means that the relation is not a function
Would you rather go with the deal : 25% off of the $40 for christmas wrapping paper or the deal for 50% off of the $62 for christmas wrapping
Answer:
50% off of the $62 for christmas wrapping is the better deal
Step-by-step explanation:
Let us compare the prices after the discount
25% off of the $40 for christmas wrapping paper
=25/100*40
=0.25*40
=$10
The new price is
40-10=$30
50% off of the $62 for christmas wrapping
50/100*62
0.5*62
=$31
The new price is
=62-31
=$31
Tanya is at a fair and has $30 to spend on x number of rides and y number of games. Each ride is $2 and each game is $3. The equation 2x+3y=30 represents this scenario. If Tanya does not play any games, how many rides can she go on?
Answer:
15 rides
Step-by-step explanation:
From the above Question we know that if Tanya goes on a ride, the Algebraic expression = 2x
Where x = number of rides
If Tanya does not play any games, how many rides can she go on?
Note that: Tanya has $30 to spend
This question is solved:
2x = $30
x = $30/2
x = 15 rides
Hence, if Tanya does not play any games she can go on 15 rides
If Clare earns $75 the next week from delivering newspapers and deposits it in her account, what will her account balance be then? her account balance is $-50 to start out with
Answer:
25
Step-by-step explanation:
because 75 - 50 = 25
The Clare account balance after the deposit of $75 will be $25.
What is subtraction?To subtract in mathematics is to take something away from a group or a number of objects.
In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.
As per the given,
The account balance initial = -$50
The amount of deposition = $75
Total amount = -$50 + $75
⇒ $25
Hence"The Clare account balance after the deposit of $75 will be $25".

State the domain and range of the relation below.
{(1, -2), (4, 5), (2, -4), (6,5), (2, 2)}
A domain = {1, 2, 4, 6) and range = {-4, -2, 2,5}

D domain = {-4, 2, 2, 5, 6} and range = {-2, 1, 2, 4,5}
* need help fast *
Answer:
The answer you are looking for is A.
Step-by-step explanation:
Remember, the domain is a set of working x values or all possible inputs of a function or two variable relationship. The range is a set of working y values or all possible outputs of a function or two variable relationship. A two variable relationship with more than one output for each input will not be a function in general but will be refered to as inverse.
Now given a set of coordinates for this relation, coordinates with x and y values or inputs and outputs are generally cartesian coordinates represented by (x,y). This is so we know the working x value for each y value, also making it easier to graph it on a coordinate plane or visualize it. x = domain (input of a function) , y = range (output of a function).
All you have to do is sort the x and y values you are given from the coordinates.
For instance, (-1,2) and (4,5) : domain of -1 and 4 [the x values], range of 2, and 5 [the y values].

work out 1/2 x 7 giving your answer as a mixed number
Answer:
[tex]4\frac{1}{2}[/tex]
Step-by-step explanation:
This question is basically saying: what is half of 7, or what is 7 divided by 2?
Based on this, it can be written both of the ways as:
»» [tex]\frac{1}{2}[/tex] of 7 OR 7 ÷ 2
So, just solve using either one and you’ll get 4.5 or [tex]4\frac{1}{2}[/tex]. But since the question wants the answer to be a mixed number, then choose [tex]4\frac{1}{2}[/tex].
Hope this helps! :)

What is Distributive Property?The distributive property is also known as the distributive law of multiplication over addition and subtraction. The name itself signifies that the operation includes dividing or distributing something. The distributive law is applicable to addition and subtraction. Let us learn more about the distributive property in this page.
The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC. This distributive law is also applicable to subtraction and is expressed as, A (B - C) = AB - AC. This means operand A is distributed between the other two operands.
Given:
48 + 72
Now, factorize the above into prime factors
48 = 2 x 2 x 2 x 2 x 3
and, 72 = 2 x 2 x 2 x 3 x 3
Now, rewriting
48 + 72
= 2 x 2 x 2 x 2 x 3 + 2 x 2 x 2 x 3 x 3
= 2 x 2 x 2 x 3 (2 + 3)
=24 (2+3)
Hence, the expression can be written as 24 (2+3).

Answer:
y=1/3x+7/3
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept
m=(y2-y1)/(x2-x1)
m=(3-1)/(2-(-4))
m=2/(2+4)
m=2/6
simplify
m=1/3
y=1/3x+b
y-y1=m(x-x1)
y-1=1/3(x-(-4))
y-1=1/3(x+4)
y-1=1/3x+4/3
y=1/3x+4/3+1
y=1/3x+4/3+3/3
y=1/3x+7/3
Lindsey Smith was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 864 points. The number of two-point field goals that Lindsey made was 62 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 30 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Lindsey Smith made during the 2006 regular season.
Answer:
Number of 3 point goals = 85
Number of 2 point goals = 3(85) - 62 = 193
Number of free throws = 3(85)- 32 = 223
Step-by-step explanation:
Given that :
2 point goals
Number of 3 point goals = x
Number of 2 point goals = 3x - 62
Number of free throws = 3x - 62 - 30 = 3x - 32
3x + 2(3x - 62)+ 3x - 32= 864.
3x + 6x - 124 + 3x - 32 = 864
12x = 864+ 124 + 32
12x =1020
x = 1020 / 12
x = 85
Number of 3 point goals = 85
Number of 2 point goals = 3(85) - 62 = 193
Number of free throws = 3(85)- 32 = 223
When Mr. Davidson preheated his oven, the oven's temperature rose 3 degrees in 1 6 of a minute. At that rate, how much will the oven heat up in 1 minute?
Answer:
18 degrees
Step-by-step explanation:
When Mr. Davidson preheated his oven, the oven's temperature rose 3 degrees in 1/ 6 of a minute. At that rate, how much will the oven heat up in 1 minute?
Solving the above question
1/6 minute = 3 degrees
1 minute = x
Cross y
1/6x = 3 × 1
x = 3 ÷ 1/6
x = 3 × 6
x = 18 degrees
The oven will heat up 18 degrees in 1 minute

let 'm' be mid value of class and 'L' be upper limit in frequency table. The lower limit of class is ? Please prove and answer
Answer:
Lower Limit = 2m-L
Step-by-step explanation:
Given that,
The mid value of class = m
Upper limit in the frequency table = L
We need to find the lower limit of the class.
The mid value of a class is given by :
[tex]\text{mid-value}=\dfrac{\text{lower limit + upper limit}}{2}\\\\m=\dfrac{L+\text{lower limit}}{2}\\\\2m=L+\text{lower limit}\\\\\text{lower limit}=2m-L[/tex]
Hence, the lower limit of the class is 2m-L.
