Answer:
ab=bc because b devide ac in two equal sizes
ac=ab+bc
ac=2×ab
ac =2×bc
lets substitute ac and bc there we are given
x+3=2(3x-1)
x+3=6x-2
-5x/-5=-5/-5
x=1
ab=3(1)-1
ab=2
I am assuming you mean 3.0 *10^8 and 1.5 * 10^11.
time = distance/speed right. So,
t = 500 s
The more digits you have the bigger the number, unless you have a long decimal, and in that case only is the number smaller in value.
I suppose you mean 5y^8.
When y = 4, we have,
5(4)^8 = 5 x 65,536 = 327,680
Answer:

Step-by-step explanation:
<u><em>The question is</em></u>
Which equation should she use?
we have the formula

Solve for k
That means ----> isolate the variable k
Multiply by 2 both sides

Divide by x^2 both sides

Rewrite
