Answer:

x = 0

Step-by-step explanation:

In order to solve for x, first combine both fractions on the left

To add 4x-2/8 + 3+x/4 first find the least common denominator of 8 and 4

It's 8 so multiply the numerator and denominator of 3+x/4 by 8, you would get:

8x+24/32

Multiply 4x-2/8 by 4, you will get:

16x-8/32

Now you can add 16x-8/32 + 8x+24/32, you would get:

24x+16/32

Now you can start to solve for x

Your new equation is 24x+16/32 = 1/2

To solve for x, first multiply diagonally, then solve like a regular equation.

Multiply 24x+16 by 2 to get 48x+32

Then multiply 32 by 1 to get 32

Your new equation is 48x+32=32

Now subtract 32 by 32 to get 48x=0

Now divide 48 by 0 to get x=0

Step-by-step explanation:

Answer:

$9450

Step-by-step explanation:

Given that:

The price of the home = $450000

The interest = 7.8%

Down payment = 30% of price of the home

i.e 0.3 × 450000 = 135000

The principal outstanding balance = 450000 - 135000

= 315000

Finally, the cost of 3 points will be;

[tex]= 315000 \times \dfrac{3}{100}[/tex]

= $9450

Answer:we can solve the problem by setting a simple proportion.

We know that 22 pancakes can feed 8 people, so we have to find the number x which corresponds to the number of people that can be feeded with 55 pancakes:

Solving the proportion, we find

So, 55 pancakes can feed 20 people.

Answer:

5c + 3d = 55

4c + 3d = 53

Step-by-step explanation:

lets pretend c= cost of chicken, d= cost of duck

5 chickens total cost would be 5c

3 ducks total cost would be 3d

in equation one added together would be 55 for total cost (given in word problem).

repeat for second equation.

Answer:

24

Step-by-step explanation:

4*6=24

Answer:

100÷170×85=$50

85-50=$35

Answer: 0 ≤ x ≤ 4

Step-by-step explanation:

The cost equation can be written as:

y = $2 + $0.75*x

Where x is the number of ounces that you buy.

If you can spend between $2 and $5, then we have the inequality:

$2 ≤ y ≤ $5

replacing y by the above equation:

$2 ≤  $2 + $0.75*x ≤ $5

Now let's solve this for x.

$2 - $2 ≤ ($2 + $0.75*x) - $2 ≤ $5 - $2

$0 ≤ $0.75*x ≤ $3

now we can divide bt $0.75 in the 3 sides:

$0/$0.75 ≤ ($0.75*x)/$0.75 ≤ $3/$0.75

0 ≤ x ≤ 4

Then the domain is:

D: 0 ≤ x ≤ 4

or we can also write this as:

D = x ∈ [0, 4]

Answer:

let the larger and  smaller number be x and y respectively

first condition

x + y = 49

second condition

3x = 2y+97

3x-2y =97

Multiplying first condition by two and adding both equations

2x + 2y = 98

3x -2y = 97

5x =  195

x = 195/5 = 39

putting the value of x in

x + y = 49

y = 49 -39 = 10

Step-by-step explanation:

Answer:

The total amount of money Bernadette earned in April was $6200

Step-by-step explanation:

Let us solve the question

∵ Each month Bernadette receives $2000

∵ She also receives a 5% commission for all of her sales

∴ She earns each month = 2000 + 5% of her sales

∵ In April, Bernadette sold $84,000 worth of used cars

→ Multiply it by 5% to find her commission

∴ Her commission = 5% × 84,000

→ Change 5% to decimal by divide it by 100

∵ 5% = 5 ÷ 100 = 0.05

∴ Her commission = 0.05 × 84,000

∴ Her commission = $4200

→ Add her commission to her fixed amount to find her salary in April

∵ She earned in April = 2000 + 4200

∴ She earned in April = 6200

∴ The total amount of money Bernadette earned in April was $6200

Answer: Bernadette works at a Car Lot in Buffalo selling used cars. Each month Bernadette receives $2000 plus she receives a 5% commission for all of her sales. In April, Bernadette sold $84,000 worth of used cars. Calculate the total amount of money Bernadette earned in April.

Step-by-step explanation:

$2000 + 5% + $84,000= 86000.05 or 86000

All you have to do is just Add - $2000 + 5% + $84,000=

And it gives you 86000.05 or 86000

Sorry if I got it wrong.

Answer:

Its 15/2 but something is probably wrong with the question.

Step-by-step explanation:

h is hard boiled eggs. s is scrambled eggs. s/h=6

15/h=6

15=6h

h=15/6=5/2 Something is probably wrong with the question because who would serve 1/2 of a egg.

Answer:

63 Seconds

Step-by-step explanation:

The reason how I got this is I divided 36 by 4 to get 9 seconds per handspring, next I multiplied 7 by 9 to get the answer.

Answer:

63

Step-by-step explanation:

If gymnast can do 4 back handsprings in 36 seconds , then for 1 backspring the gymnast took 36/4 = 9 seconds.

If the gymnast took 9 seconds for 1 back handsprings, Time taken by the gymnast to do 7 backsprings = 9×7 = 63 seconds

Answer:

y intercept = [tex](0, ~-\frac{5}{2} )[/tex]

x intercept = [tex](-2, ~0)[/tex]

.

Step-by-step explanation:

[tex]-5x - 5y = 10[/tex]

.

y intercept

[tex]\to x = 0[/tex]

[tex]-5(0) - 4y = 10[/tex]

[tex]-4y = 10[/tex]

[tex]y = \frac{10}{-4}[/tex]

[tex]y = -\frac{5}{2}[/tex]

so, the answer is [tex](0, ~-\frac{5}{2} )[/tex]

.

x intercept

[tex]\to y = 0[/tex]

[tex]-5x - 4(0) = 10[/tex]

[tex]-5x = 10[/tex]

[tex]x = \frac{10}{-5}[/tex]

[tex]x = -2[/tex]

so, the answer is [tex](-2, ~0)[/tex]

.

Answer:

560 students

Step-by-step explanation:

We are given that the total number of students is

700

The survey results is 80% likes the new lunch menu

We are expected to establish what amount of students is 80%

=80/100*700

=0.8*700

=560

Hence 80% of 700 is 560

Answer:

yea the answer  is a -27

Step-by-step explanation:

2 x 9 = 18

3 x 9 = 27

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 7x - 10 ← is in slope- intercept form

with slope m = 7

Parallel lines have equal slopes, thus

m = 7 and point on line is T(- 3, 3 )

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line, then

y - 3 = 7(x - (- 3) ), that is

y - 3 = 7(x + 3) → D

Answer:

C. 8

Step-by-step explanation:

f(5) =1/4(2)^5

because x=5

f(5)=1/4(32)

because 2^5 is 2*2*2*2*2=32

f(5)=8

because 1/4*32 or 32/4 is 8

Hope this helped :) I haven't even learned f(x) in school yet haha. I'm in 8th grade, but I took extracurriculars for math and I'm on the math team. Ergo, I know it's right!

Answer:

The answer is -8/3.

Step-by-step explanation:

First, you have to make y the subject :

8x + 3y = 9

3y = -8x + 9

y = (-8/3)x + 3

In a linear equation, y = mx + b, m represent gradient (slope). So in this equation the slope is -8/3.

6 games

Step-by-step explanation:

Joey has won 3 out of the last 8 games of cards he has played with his brother. They play 16 more games, how many of those games does Joey expect to win?

8 games = 3 won

16 games = x

Cross Multiply

8x = 16 × 3

8x = 48

x = 48/8

x = 6

If they play 16 more games, Joey expects to win 6 games

Answer:

6 games

Step-by-step explanation:

2 x 8 = 16 so, if he won 3 out of 8 he will expect to win another 3 games.
