Answer:
23
Step-by-step explanation:
First, do 28 times two, since he's getting twice as many colored pencils. You should get 56. Then you take 11, and since he has 3 sisters you multiply it by three. Then you have 33. When you get this, you need to subtract 33 from 56. You should get 23 and that's your answer.
Answer:
A
Step-by-step explanation:
To solve this problem, you set up the equation 45+(2x-5)=180
Next, subtract 45 from 180 to get the equation 2x-5=135
After that, add 5 to 135 to get 2x=140
Diviode 140 by 2 to get X=70
