Please use " ^ " to indicate exponentiaton: <span>Use the equation
350 = (270)(1.05)^x.
Take the log of both sides:
log 350 = log 270 + x*log 1.05.
Subtr. log 270 from both sides:
log 350 - log 270 = x*log 1.05
log 350 - log 270
Sove for x: x = -------------------------
log 1.05
2.544- 2.431
Evaluate this using a calculator. x = ------------------
0.0212
x is then approx. 5.33, or 5 1/3 years.

We have to solve x in terms of a, b and c:
a x - 3 b = c
a x - 3 b + 3 b = c + 3 b
a x = c + 3 b
x = ( c + 3 b ) : a
Answer:
4 ) ( c + 3 b ) / a
P(7) = 1/8 = 0.125 out of 1
Answer:
8.5
Step-by-step explanation:
It would be 28.5. First, you would find the area of the smaller triangle by using the formula a=.5bh (area=.5xbasexheight) and then when you get that, you should get 6. Then, you do the same for the larger triangle and you should get 22.5. Then, 22.5 + 6 = 28.5, giving you that answer.
