Answer:
$180
Step-by-step explanation:
To solve, we can set up a proportion and solve.
You earn $45 for 7.5 hours of work, and you earn $ x for 30 hours of work
45/7.5=x/30
Cross multiply
45*30=7.5*x
1350=7.5x
To solve for x, we need to get x by itself. It is being multiplied by 7.5. To undo this, divide both sides by 7.5
1350/7.5=7.5x/7.5
180=x
So, for 30 hours of work, you would earn $180
Answer:
Step-by-step explanation:
Y = - 3x. Equation 1
x + y = - 4 equation 2
Putting value of y
x + (-3x) = - 4
x - 3x = - 4
-2x = - 4
x = - 4/-2 = 2
Putting value of x in the equation 1
Y = - 3(2)
Y = - 6
Answer:
x = z - m
Step-by-step explanation:
<u>Solving for x with steps:</u>
- z=m+x
- x + m = z
- x + m - m = z - m
- x = z - m
(-8)*(-7)=(-15)
the 2 in the beginning stays the same, and you multiply what’s in the parentheses to get (-15)
