Answer:
Longest side is 18 m
Step-by-step explanation:
1st side : x -9
3rd : 3(x-9)
If perimeter is 39, then, x + (x-9) + 3(x-9) = 39
5x -36 = 39
5x = 75
x = 15
Therefore,
1st side = 6
2nd side = 15
3rd side = 18
Answer:
35 inches long
Step-by-step explanation:
the answer is 35 inches long because if you do 38x2 because of the two sides you will get 76 then subtract 76 from 146 then you will get 70. Then do 70÷2 to find out the other side and i got 35
We are given that
Max's grade on the first math exam was a 94
so, first exam grade =94
His grade on his seond math exam was an 89
so, second exam grade =89
change in grade=(first exam grade)-(second exam grade)
change in grade=94-89
change in grade=5
Percentage = ( change in grade)/( first exam grade) *100
so, percentage is
so,
the percent of change in Max's grade to the nearest whole percentage was 5%..........Answer
