C.
z = 20

D.
z = 44
i think its either 20 or 44

Hey that’s the problem I put in my classes test

QUICKEST GETS BRAINLIEST AND 10 POINTS!!! PLEASE HURRY!! SPAM WILL BE REPORTED!!David and Amanda are trying to figure out how long they can live off their $12,350 savings if they spend $240 each month. They have each created an equation.

David’s Equation Amanda’s Equation
y = 12,350 – (240x) y = 12,350 + (240x)
Which person has the correct equation to model this linear relationship?

Amanda’s equation is correct, because their spending will be multiplied by the number of months and then added to their savings.

Amanda’s equation is incorrect, because their spending will increase the amount of their savings.

David’s equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings.

David’s equation is incorrect, because their spending should be a fixed amount and should not be multiplied

Answers

C "David’s equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings" is the correct answer
C.) David’s equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings. 

The equation would be: y = 12,350 - 240x
where, x = number of months

Hope this helps!

3x-4y=-31 x=6-y please help

Answers

Solve x

Substitute -y+6 for x in 3x-4y=-31

3x-4y=-31

3(-y+6)-4y=-31

Simplify both sides of the equation

-7y + 18 = -31

Add -18 to both sides

-7y+18-18=-31-18

7y= -49

Divide both sides by -7

7y/-7= -49/-7

y= 7

Substitute 7 for y in x = -y+6

x= -y+6

x= -7+6

Simplify both sides of the equation

x= -1

Answer : x= -1 and y = 7


I hope that's help and have a great night !

Turn 8/200
into a decimal using an equivalent fraction show your steps

Answers

First I'd reduce it to 4/100 because every fraction is easier to make a decimal over 100. Now write the four and for every extra 0 add a 0 between the decimal and the number. the answer is 0.04 but also remember when using this trick. If the number over 100 has a decimal you have to keep those ones too
8/200
= (8/2) / (200/2)
= 4/100 (equivalent fraction)
= 0.04

The final answer is 0.04~
