10x - 40 + 15 = -15 (use distributive)
10x - 25 = -15. add integers on left

10x = 10 add 25 to both sides
x = 1 divide by 10

Answer:

x = 1

Step-by-step explanation:

Given

5(2x - 8) + 15 = - 15 ( subtract 15 from both sides )

5(2x - 8) = - 30 ( divide both sides by 5 )

2x - 8 = - 6 ( add 8 to both sides )

2x = 2 ( divide both sides by 2 )

x = 1

(4x^5 + 3x^2 – x^4) +(6x^2 - 2x^5)
Monica [59]

Answer:

The simplified equation is as follows 2x^5 -x^4 + 9x^2

Step-by-step explanation:

Remove the parentheses around each equation and pair like exponents together

4x^5 - 2x^5 - x^4 + 3x^2 + 6x^2

Then combine the like terms

2x^5 - x^4 + 9x^2

It is in that order due to the proper form being to go from the highest to lowest exponents in an answer

Damon can flip 5 pancakes in 20 seconds,
katen-ka-za [31]

Answer:

24 + 30 = 54 pancakes flipped in 2 minutes :)

Step-by-step explanation:

damon = 5 pancakes in 20 seconds

we do 20 x 3 and 5 x 3 to find how many pancakes he can flip in a minute

15 pancakes and a minute, we then multiply them by 2 to get the amount for 2 minutes

30 pancakes flipped in 2 minutes

Hailey = 2 pancakes in 10 seconds. to make it an equal amount of pancakes per second with damon, i will multiply them by 2 to have 4 pancakes in 20 seconds

we will then do 4 x 3 and 20 x 3 to find out how many pancakes per minute

then we multiply by 2 for 2 minutes
