72 times/ 1 minute= x times/ 15 minutes
2. Do 72 times 15 which equals 1,080
3. 1,080 divided by 1 equals 1,080
4. Your answer is 1,080 times

Answer: To do it just change 60 seconds to 1 minute then times 72 by 15 which would equal 1080 then your done

To check it just reverse the calculation so do 1080 divide by 15 which should equal 72

Solve for x.6 – 3(2x – 4) = 2(1 + x)

A. -2
B. 0
C. -1
D. 2

Answers

6 - 3(2x - 4) = 2(1 + x) Use the Distributive Property (Multiply the number on the outside of the parentheses by all of the numbers in parentheses to get rid of the parentheses.)
6 - 6x + 12 = 2 + 2x Isolate the variable. Start by subtracting 2 from both sides.
6 - 6x + 12 - 2 = 2x Combine like terms. (6, 12, and -2)
16 - 6x = 2x Add 6x to both sides to get all the x's on one side of the equation.
16 = 8x Divide both sides by 8.
2 = x

X equals D. 2 .

Hi Brainiac

6 - 3(2x - 4) = 2(1 + x)
Use the distributive property
6+(-3)(2x)+(-3)(-4) = (2)(1)+(2)(x)
6 - 6x + 12 = 2 + 2x
Now we need to combine like terms
-6x +(6+12) = 2x +2
-6x + 18 = 2x + 2
-6x -2x = 2 - 18
-8x = -16
x = -16/-8
x= 2

I hope that's help... If you have any further questions please let me know. Good night :)
