Answer: The boys made up 6b of the original class.
Step-by-step explanation:
He can divide the line into 1.21 sections. To determine this you need to take the length of the line and divide it by the length of the segments you want to make, in this case it equals to 1.21.
For this case we have the following equation:
We apply distributive property on the left side of the equation:
Subtracting from both sides of the equation:
Subtracting from both sides of the equation:
We multiply by 3 on both sides of the equation:
We multiply by -1 on both sides of the equation:
The solution of the equation is
ANswer:
Solve for the Volume of each box by multiplying the dimensions together.
Box 1: 10*10*10 = 1000
Box 2: 20*5*10 = 1000
Box 3: 8*8*10 = 640
Box 4: 10*20*6 = 1200
Since 640 is less than 924, Box 3 is too small
You subtract 5 from both sides and get
X<2-5
Then you just solve how it is and keep the inequality
