Find the value of y when x equals 0 , -3x-9y=36
Alchen [17]

Answer:

-3x - 9y = 36

If x = 0

Step-by-step explanation:

1. Plug 0 to x:

-3(0) - 9y = 36

2. Simplify

0 - 9y = 36

3. Cross out the 0 to make the question faster to solve, which now you are left with:

-9y = 36

4. Divide both sides by -9:

-9y/-9 = 36/-9

5. Simplify:

y = -4 <--------Answer

Hope this Helped!!!!!

Ida needs to hire a singer for her wedding. Singer A is offering his services for an initial $95 in addition to $12.95 per hour.
Ludmilka [50]

Answer:

The answer is 3.6

Step-by-step explanation:

Step one:

Singer A is offering his services for an initial $95 in addition to $12.95 per hour

let the number of hours be x and the total charge be y

the expression for the total for singer A is

y=12.95x+95----------2

Singer B is offering her services for an initial $99 in addition to $11.85 per hour

let the number of hours be x and the total charge be y

the expression for the total for singer A is

y=11.85x+99----------2

Step two:

Equating 1 and 2 we have

12.95x+95=11.85x+99

collect liker terms

12.95x-11.85x=99-95

1.1x=4

divide both sides by 1.1

x= 4/1.1

x=3.63

to the nearest tenth it is 3.6

A parking attendant charges a different rate for cars than for trucks. It costs $10.75 to park 3 cars and 2 trucks. It costs $12
timurjin [86]

Answer:

$1.25 to park a car and $3.50 to park a truck

Step-by-step explanation:

Set up a system where c is the number of cars parked and t is the number of trucks:

3c + 2t = 10.75

7c + t = 12.25

Solve by elimination by multiplying the bottom equation by -2 to eliminate t:

3c + 2t = 10.75

-14c - 2t = -24.5

Add them together and solve for c:

-11c = -13.75

c = 1.25

Then, plug in 1.25 as c in the equation to solve for t:

3c + 2t = 10.75

3(1.25) + 2t = 10.75

3.75 + 2t = 10.75

2t = 7

t = 3.5

So, it costs $1.25 to park a car and it costs $3.50 to park a truck

If QR=x+29 and PS=x–16, what is the value of x?
Juli2301 [7.4K]

Answer:

  61

Step-by-step explanation:

PS is a midsegment of the triangle, so is half the length of the parallel base segment.

  2PS = QR

  2(x -16) = x +29 . . . . . substitute given expressions

  2x -32 = x +29 . . . . . eliminate parentheses

  x = 61 . . . . . . . . . . . . add 32-x
