Answer:
1a. E = IR, I = 5, R = 3
E = 5 × 3
E = 15
b. A = πrl, π = 3.14, r = 5, l = 20
A = 3.14 × 5 × 20
A = 314
c. S = 90 ( 2n - 4 ), n = 6
S = 90 ((2 × 6) - 4)
S = 90 ( 12 - 4 )
S = 90 ( 8 )
S = 720

Answer: ( D) 998 is the greatest three digit positive integer
Step-by-step explanation: Your welcome.
Your equation will be
15.99x + 12.54y ≤ 125
Hope this helped
If y varies directly with x, then whatever is done to y is also done to x, and vice versa.
All of the answers relate to when the value of y is positive 1, meaning we have divided the original y by -10.
We must also do this to x, as they are directly proportionate, meaning x = 2 now becomes x = -1/5
Therefore the answer is [B]
