2x+2+x=20
3x+2=20
3x+2-2=20-2
3x=18
18/3=6
So x=6
So the shorter one is 6ft and the longer piece is 14ft. (Additional work to help support answer more) 14+6=20 and 6*2+2=14.

Answer:
23.142857143 calories or 23 1/7 calories
The unit rate is calories per cup
Step-by-step explanation:
7- cup serving = 81 calories
2 cups = x calories
Cross Multiply
2 cups × 81 calories = 7 cups × x
x = 2 cups × 81 calories/7 cups
x = 23.142857143 calories or 23 1/7 calories
You can solve all of these by using the distance formula. I have shared it below.
