R=16
J=32
20+40(which is 20×2)=60
20-4=16
16×2=32
Answer:
numbers are 3x,2x,5x
so 3x+2x+5x=10x=840
so x=84
so numbers are 252,168,420
treat the tree trunk as a cylinder
v= pi x r^2 x h
using 3.14 for pi
3.14 x 3^2 x 10 = 282.6 cubic feet
282.6 * 45 = 12, 717 pounds
Answer:
85° and 95°
Step-by-step explanation:
So, one angle is x, the other angle is x + 10. Using this, you can form an equation.
x + x + 10 = 180
Now, solve the equation.
2x + 10 = 180
2x = 170
x = 85
So, one angle is 85 while the other angle is 95.
85 + 95 = 180,
so we know that our answer is correct.
