100%
98% or better
96% or better
90% or better

9. The measure of an acute angle is less than 90 degrees. If an acute angle measures 3x - 15, then the inequality to represent its measure is 3x - 15

Question

8. Steve has these scores on the exams for this semester: 89, 92, and 87. How much will he have to make on the fourth exam to have a final average of an A (a 92% or better)?(Points : 1)  
       100%
       98% or better
       96% or better
       90% or better
  
    
9. The measure of an acute angle is less than 90 degrees. If an acute angle measures 3x - 15, then the inequality to represent its measure is 3x - 15 < 90. Solve to find the measure of x.(Points : 1)  
       x < 25
       x < 35
       x < 45

1) 92*4 to know the total score he must get to average 92%.
Then, solve (92*4)-(89+93+87) to get your answer.

2) 3x - 15< 90
    3x < 90 +15
Solve for x
