It’s the 3rd option. It would be that bc you are checking by rounding your number up.
Given the equation 9x = -63, the numerical value of x is -7.
<h3>What is the solution to the given equation?</h3>
Given the equation in the question;
9x = -63
To determine the value of x, we divide both sides by the coefficient of x.
9x = -63
9x/9 = -63/9
x = -7
Given the equation 9x = -63, the numerical value of x is -7.

Answer:
212.5/h
Step-by-step explanation:
subtract the new value from the old value, then divide by the time.
(1530 - 680)/4
850/4
212.5/1h

100+25*12=
100+300=
400
400-320=80
I=PRT
I=80
P=principal=320
T=1 year
R=?
80=320*1*?
80=320?
divide both sides by 320
0.25=?
that is 25%
answer is 25%
