If y represents total earnings in dollars and x represents hours worked, then which equation models the wages of someone who makes $9.50 an hour?

a. x = 950x
b. y = 950x
c. x = 9.50x
d. y = 9.50x

Option D is correct

Step-by-step explanation:

Here, y represents total earnings in dollars and  x represents hours worked.

As per the statement:

To find which equation models the wages of someone who makes $9.50 an hour.

translated to 9.50x

then;

the total earning in dollars we get;

Therefore, an equation models the wages of someone who makes $9.50 an hour

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
