Answer:

$ 9

Step-by-step explanation:

Simple Interest = P.R.T / 100

P = Principal (Amount invested) =$30

R = Rate= 10%

T = Time = 3 years

Therefore, Simple Interest (I):

I = PRT/100

I = ($30 * 10 * 3 ) / 100

I = $900 / 100

I = $9

She will have a total of $9 in three years

-1/2x = -7 please answer I need help
Sloan [31]

Answer:

x = 14

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Multiply -2 to both sides of the equation:

-2 * (-1/2x) = -2 * -7

x = -2 * -7

x = 14

Note that when you multiply two negative numbers, the answer will be positive.

14 is your answer for x.
