H=-5 and w=2, work out the value of 4h-3w
olganol [36]
You would simply have to plug in, or substitute, the given values in the equations.

So, H=-5, W=2 and the problem is 4h-3w

To plug them in, your new equation would be 4(-5)-3(2) and simplify. So it becomes -20-6 which = -26. 

And -26 would be your answer.

MA_775_DIABLO [31]

Answer: 31.2 pies

Step-by-step explanation:

Kim sold pies for $5.00 each and earned $156 from doing so.

The number of pies she sold to get to this was x pies.

The formula for doing so is therefore:

5 * x pies = 156

5x = 156

x = 156 / 5

= 31.2 pies

Solve the equation below for x.<br> сх — 4 = 7
RoseWind [281]

Answer:

x = 11/c

Step-by-step explanation:

To solve this equation for x, we simply need to apply equation operations and isolate the x variable.

cx - 4 = 7

cx - 4 + 4 = 7 + 4

cx = 7 + 4

cx = 11

cx * (1/c) = 11 * (1/c)

x = 11 * (1/c)

x = 11/c

Cheers.
