The diameter of this is 5 so you would do 5xπ=15.7 (1 decimal place)
Answer:
5x + 16
Step-by-step explanation:
the first thing you do in this equation is to distribute the 2 into x + 6
you get
2x + 12 + 3x + 4 = ?
then you must put the 2x and the 3x together
5x + 12 + 4
and you can then add the 12 and 4
5x + 16
a+b=350 => a=350 - b
3a + 5b = 1450
3(350-b)+b=1450
1050-3b+5b=1450
2b=400
b=200
a=150
