Answer:
x=19
Step-by-step explanation:
8x-7 + x+16 = 180
solve for equation for x
9x = 171
x=19
Hello from MrBillDoesMath!
Answer:
7.7 % (approximately)
Discussion:
65 * x% = 65 * (x/100) = 5 => (multiply both sides by 100)
65 *( x/100)* 100 = 5 * 100 =>
65x = 500 =>
x = 500/65 = 7.7 (approx)

P.S. I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!
we know that
The simple interest formula is equal to
where
P is the Principal amount of money to be invested
I is the amount of money in interest
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above and solve for P
![P=14.65/[(0.025)(2)]](https://tex.z-dn.net/?f=P%3D14.65%2F%5B%280.025%29%282%29%5D)
therefore
<u>the answer is</u>
Okay, so first, lets determine whether or not these are equivalent, which will lead us to our answer.
8/12 < lets simplify this
8/4 = 2
12/4 = 3
8/12 = 2/3
10/25
10/5 = 2
25/5 = 5
10/25 = 2/5
2/5 ≠ 2/3
These ratios are not proportional.
