Four times a number plus five times the number is the same as ten more than eight
times the number. Find the number
Answer:
The number is 10.
Step-by-step explanation:
Given that:
Four times a number plus five times the number is the same as ten more than eight times the number.
Let,
x represent the number.
According to given statement,
4 times the number + 5 times the number = 10 + eight times the number
4x+5x=10+8x
Solving the equation,
9x=10+8x
Subtracting 8x from both sides
9x-8x=10+8x-8x
x=10
Hence,
The number is 10.
4 × (3 + 7) = (4 ×[]) + (4 ×[])
Answer:
4 × (3 + 7) = (4 ×7) + (4 × 3)
Step-by-step explanation:
If you go by the order of PEMDAS you would do the parentheses first. 3 + 7 =10. 10 × 4 = 40. Then you would just use the distributive property and do (4× 7) + (4 × 3)
4 × 7 = 28 and 4 × 3 = 12 28 +12 =40

A scuba diver is swimming at a depth of 46 meters below sea level. He swims 0.5 meters toward the surface every 3 seconds.
What is his location relative to the surface after 15 seconds?
Answer:
The scuba diver would be 43.5 meters from the surface after 15 seconds
Step-by-step explanation:
So first we need to take 0.5 and multiply it by 5 since we know 15 divided by 3 is equal to 5, and we get 2.5
We then take 46 and subtract 2.5 from it, resulting in 43.5

Answer: (-∞, 3.5)
Step-by-step explanation:
Here we can use the relation:
Exp( Log(X)) = X
Now, we start with the equation:
log(x + 7) > log(3x)
Now we can apply the exponential function to both sides of the inequality to get:
Exp(log(x + 7)) > Exp(log(3x))
x + 7 > 3x
7 > 3x - x
7 > 2x
7/2 > x
3.5 > x
Then the solutions will be all the values of x smaller than 3.5, this set can be written as:
(-∞, 3.5)

O 1
o 351..-1, -21, F3
o 35,-12,-
Answer:
The first one

Note the brackets means absolute value so the order of the first one goes like this
-1, 3/2, 2, 3, 3.5
Thus it's from least to greatest
lake in East Texas was stocked with 3,000 trout in the year 2000. The number of fish in the lake is modeled by f(x) = 3000 + 100x, where x represents the number of years after 2000.
Which of the following is the most reasonable domain and range for the function?
Answer:A
Step-by-step explanation:A
The most reasonable domain and range for the function is x≥0, y≥0. Therefore, option B is the correct answer.
The given function is f(x) = 3000 + 100x.
We need to find which of the following is the most reasonable domain and range for the function.
What is the domain and range of the function?The domain and range are defined for a relationship and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:
Domain = the set of all x-coordinates = {1, 2, 3, 4}
Range = the set of all y-coordinates = {2, 3}
Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Domain: (-∞, ∞) {x|x∈R}
Range: (-∞, ∞) {y|y∈R}
The most reasonable domain and range for the function is x≥0, y≥0. Therefore, option B is the correct answer.

Lola's hockey team lost 15% of
their games this season. If they
lost 3 games, how many games
did they play in total?
(show your work)
Answer:
[tex]20[/tex]
Step-by-step explanation:
Let [tex]x[/tex] = games played in total
From the fact that [tex]15\%[/tex] of the games the team played is equivalent to [tex]3[/tex] games, we can write:
[tex]15\%x = 3[/tex]
[tex]x=3\div 15\%[/tex]
[tex]=20[/tex]
∴ Lola's hockey team played a total of 20 games.

Which statement correctly describes the relationship between the graph of f(x) and g(x)=f(x−7)?
The graph of g(x) is the graph of f(x) translated 7 units down.
The graph of g(x) is the graph of f(x) translated 7 units left.
The graph of g(x) is the graph of f(x) translated 7 units right.
The graph of g(x) is the graph of f(x) translated 7 units up.
Step-by-step explanation:
When the number is inside the parenthesis. It means horizontal shift. Now negative is to the right and positive is to the left. Since it is negative 7 it would be 7 units to the right

Here are the prices of some items and the amount of sales tax charged on each in Nevada. row 1 cost of item ($) sales tax ($) row 2 10 0.46 row 3 50 2.30 row 4 5 0.23 What is the sales tax rate in Nevada
Answer:
4.6%
Step-by-step explanation:
Cost of item __ sales tax
10 ___________0.46
50 __________ 2.30
5 ___________ 0.23
To obtain the sales tax % :
Sales tax % * cost of item = amount of sales tax
Let sales tax % = x
Using any of the rows in the table :
x * 10 = 0.46
x = 0.46 / 10
x = 0.046
x = (0.046) * 100% = 4.6%

Find the equation of the line.
Use exact numbers.
y =
x+
Can I please get an explanation :)
Answer:
the equation is in form
y=mx+b where
m=slope
and
b=y-int (the y value for the vertex)
first we look to see what the y value is for the point where x=0 and we can see that it is 5 so b=5
then we look at the slope, slope it the amont of units up then to the side are needed to reach the next point, in this case the line goes up 1 then to the right 1 so the slope is 1/1 (1) so the full equation is
y=x+5
