It's the first one because
3/5/3/8 = 3*8/5*3 = 24/15 =1 3/5
Answer: 5^2
Step-by-step explanation:
Since the base are all the same, you will add the exponents and let the exponents stay the same.
5^3 * 5^4= 5^7 * 5^-5= 5^2
Answer:
The percent change is 50%
Step-by-step explanation:
The savings account lost $750. When the amount lost is the same amount you have left, it signifies that the amount lost is half as much as you had.
Half of the total is represented as 50%.
<u>Check Work:</u>
1500 x 0.5(50%*) = 750
1,500 - 750 = 750
Ok so to solve for percent off
percent off means discount
so therefor we need to find how much was discounted
30-20.10=9.90
so we see that 9.90 was discounted
to find the percent we do
discount/total=percent discount
9.90/30=0.33
percent means parts out of 100
0.33/1 times 100/100=33/100=33%
answer is 33% discout
0 = x^2 + x - 72
x^2 + x - 72 = 0
x^2 + 9x - 8x - 72 = 0
X (x + 9) - 8 (x + 9) = 0
(X + 9) (x - 8) = 0
X + 9 = 0
X = -9
X - 8 = 0
X = 8
X (-9,8)
Answer is Option D
x = -9 or x = 8
