Answer:
x = 7
3x + 11 = 32
8x + 2 = 58
Step-by-step explanation:
3x + 11 + 8x + 2 = 90
11x + 13 = 90
11x = 77
x = 7
3x + 11 = 3(7) + 11 = 32
8x + 2 = 8(7) + 2 = 58
Draw a vertical line at the number 4 on your x axis positive side which is x=4
Then anything on the left of this line you just created at x=4 will be less than 4. But since your inequality is x less than/equal to 4 it includes 4 as well.
34% = 0.34
120 * 0.34 = 40.8
Solution: it is 40.8
S.I = PxRxT / 100
Therefore
S.I.= $10000x3x6/100
=$900
S=49p+7*9p=(49+63)p=112P
answer is B
