Answer:
r = -4/5
Step-by-step explanation:
Divide both sides by 15 so you have r
-12/15 simplify (both by 3)
-4/5
Answer:
B
Step-by-step explanation:
This is a simple interest problem. The formula for simple interest is:

Where
i is the interest amount
P is the principal amount
r is the rate of interest
t is the time in years
Given P, r, and t, we need to find convert r (as a percentage) to a decimal. We simply divide by 100. Shown below:
r = 7% = 7/100 = 0.07
Now, we substitute into formula and find i (interest):

Correct answer is B, $42
Answer:
A, C, F.
Step-by-step explanation:
A polynomial consists of an expression that involves only non-negative integer exponents for the variable; in all of your cases, the variable is x.
So, expression A has a square root of x, that is a rational exponent.
Expression C has variables in the denominators, that is negative exponent.
Expression F has variable at the exponent.
Answer:
no
Step-by-step explanation
m=18
the reason why is because 5+4 =9 so 9*2=18
18/2=9
9-4=5
