Answer:
-5
Step-by-step explanation:
multiply both sides of the equation by the denominator(12)
thus giving:
14+10x=-3(12)
14+10x=-36
take 14 to the other side;
10x=-36-14
10x=-50
divide both side by 10
x=-5
Answer:
a <= 3
Step-by-step explanation:
add 4 to both sides then divide by 3 to isolate a
Answer:
7
Step-by-step explanation:
The formula would be c=(320/x)+3
C is the total chairs and x is the price per chair and we add 3 since she is getting 3 for free
Following PEMDAS, we should do 320/80 first which is 4
Then the equation becomes 4+3=7
Answer:
D. Nine months
Step-by-step explanation:
Simple interest=principal×rate×time
Principal=$1800
Rate=4.5%
Time=?
Interest=$60.75
Simple interest=principal×rate×time
60.75=1800×4.5×t/100
60.75=8100t/100
60.75=81t
t=60.75/81
t=0.75 year
0.75 years=9 months
