X=7 that is your answer because you add 3 to both sides and you are left with x=7
Answer:
The third option
Step-by-step explanation:
C
work:
75 is equal to 2x+15
75-15 = 60
60/2 = 30
x=30
First, let's solve the inequality:
Subtracting 4 from all 3 terms, we get -6 < 3x < -2
Solving -6 < 3x results in x>-2, and solving 3x < -2 results in x < -2/3.
Ask: which integers satisfy x>-2? Answers: -1, 0, 1, 2, ....
Also ask: which integers satisfy x < -2/3? Answers: -5, -4, -3, -2, -1
Notice that the only integer that is found in both sets of possibilities is -1. So, only one integer x satisfies the given inequality.
Answer:
90 balls
Step-by-step explanation:
Set up proportion
36/x = 40/100
Cross multiply: 40x=3600
Solve for x
x=90
To check work:
40 percent of 90 would be 36
90(0.4)=36
