I think 121
406 + 94 = 500 and 180 + 199 = 379.
Subtract that and 121 is what’s left.
Answer:
5< 10x -3
add like terms first
make sure X's are on one side and numbers on the other
Answer:
12 months
Step-by-step explanation:
Based on the question
4 books equals to 5 months
x books equals to 15months
To determine the value of X we will have to cross multiply,it means
5x=15×4
5x=60
Divide both sides by 5
x=12
Therefore,x=12
Which means 12 books equals to 12 months
Circumference = 2 pi r = 20 pi
corresponding to 360 degrees
so an arc of 4pi feet will have a degree measure of 5pi / 20pi * 360 = 1/4 * 360 = 90 degrees
