Answer:
9
Step-by-step explanation:
The first operation is what inside the braces
1-first comes the multiple and the division
2- then the + and the -
1- (25-36)+5(8-4)
2- (25-36) + 5×4
3- (-11) + 20 =9
<span>14n- 7= 49
Add 7 to both sides
14n=56
Divide 14 on both sides
Final Answer: n=4</span>
Answer:
2X+4X=Y just switch it. Technically its still the same problem
Step-by-step explanation:
Answer:
Step-by-step explanation:
moments about the fulcrum should be equal
IF x is the distance of the fulcrum from the 90 lb child
90[x] = 60[12 - x]
90x = 720 - 60x
150x = 720
x = 4.8 ft
90(4.8) = 432 ft•lb
60(12 - 4.8) = 432 ft•lb
I'm guessing the power series given is

which you can condense somewhat into

You should recognize this as a geometric series, which converges for
