Answer: 46.05
Step-by-step explanation:
1/3 * 3.14 * 4 * 11 = 46.05 (rounded to the tenth)
1) x+17=20
x-10=30
2) x/4=20
x/30=2
3) 4(x+5)=40
4) x+3.2=6
5) A pizza place sells pizza for $5 per box. If I had $20 how many pizzas can I buy in all? (5x=20)
Hope this helps! Have a wonderful day.
Answer:
2a +2b +4
Step-by-step explanation:
The perimeter is the sum of the lengths of the three sides. If x represents the length of the third side, then ...
(3a +8) +(5a +b) +x = (10a +3b +12)
Subtracting from the equation everything on the left side that is not x, we get ...
x = (10a +3b +12) -(3a +8) -(5a +b)
= a(10 -3 -5) +b(3 -1) +(12 -8)
= 2a +2b +4
The length of the third side is 2a +2b +4.
