Answer:
36-5y-y^2
Step-by-step explanation:
multiply 9 and 4 to get 36
expand to get -9y+4y=-5y
-y*y=-y^2
You multiply 76 by 0.93. That is 70.68 which rounds to 71. To check, (71/76) = ~93.
6x - 2 = -4x + 2
Spencer: 6x - 2 = -4x + 2 /+4x6x - 2 + 4x = -4x + 2 + 4x10x - 2 = 2
Jeremiah:6x - 2 = -4x + 2 /-6x6x - 2 - 6x = -4x + 2 - 6x-2 = -10x + 2
They both are correct. But in Jeremiah's version of solving the equation, we would have to multiply equation by -1, which we don't have to do in the Spencer's version.

(-10) + 14 + 25 + (-16) Add 14 and 25
(-10) + 39 + (-16) Change 39 + (-10) to 39 - 10
(-10) + 39 - 16 Subtract 16 from 39
(-10) + 23 Change (-10) + 23 to 23 - 10
23 - 10 Subtract 10 from 23
13
*Remember, you can rearrange expressions like this as long as each number keeps its sign. Notice that (-10) had its negative sign the whole time, even though we moved it around.
The answer is 46 people because you have to multiply 40X.15 to get 6. Then you add 40+6=46
