Answer:

x=7

Step-by-step explanation:

3(2x - 5) = 9(10 - x)

6x-15=90-9x

6x+9x=90+15

15x=105

x=7

Answer:

x = 7

Step-by-step explanation:

First, we need to expand the brackets:

3(2x-5)=9(10-x) (equation given)

6x-15=90-9x

15x -15 = 90 (add 9x on both sides)

15x = 105 (add 15 on both sides)

x = 7 (divide by 15 on both sides)

Hope this helps :)

Callie got 37 pieces of Halloween candy. Her brother got 42 pieces. She wants to estimate to find about how many pieces of candy
Vikki [24]

Answer:

Callie needs to hide both her and her brother's candy from him so that none is eaten/stolen.  Then count each stash separately.  Put the candies in groups of 10 to quickly establish that over 70 pieces were collected.  Callie should steal a stack from her brother's pile while he's not looking.  Just calmly shift one stack of ten candies to her side.  She should announce she got 47 pieces and her brother only 32.
