| -24x + 120| > 48
-24x + 120 > 48
-24x > 48 - 120
-24x > - 72
x < -72/-24
x < 3
-24x + 120 < -48
-24x < -48 - 120
-24x < - 168
x > -168/-24
x > 7
solution is : x < 3 or x > 7...answer B
Answer:
15%=15/100=0.15
15% off means = regular price - (15% of regular price)
= 300 - (0.15*300)=255
So sale price is $255

Answer: B
Step-by-step explanation:
To solve the system of equations, use substitution.
x+y =24
Subtract x on both sides
y=-x+24
We can now substitute -x+24 in for y in the second equation.
3x+5y=100
3x+5(-x+24)=100
Distribute the 5
3x-5x+120=100
Subtract the 120 on both sides
-2x=-20
Divide by 2 on both sides
x=10
Substitute 10 in for x in the first equation.
x+y=24
10+y=24
Subtract 10 inches on both sides
y=14
So there are 10 3point questions and 14 5 point questions, so choice B
