Math is not exactly my strongest link, but I would say the answer to this would be C
Answer: M = ⁹/₅S
Step-by-step explanation:
M ∞ S -------------------------------- 1
M = KS ------------------------------ 2
K is a constant and need to be calculated
substitute for M and S in 2 to find K
900 = K500
K = ⁹⁰⁰/₅₀₀
= ⁹/₅
Therefore , the equation that connect / relates M to S will be
M = KS
M = ⁹/₅S
4(x - 3) = -12
4(x) - 4(3) = -12
4x - 12 = 12
+ 12 + 12
4x = 24
4 4
x = 6
Assume that the number is n.
sum of twice the number and 15 means that you will first multiply the number by 2 then add 15.
the equation us:
2n + 15 = -42
2n = -42-15
2n = -57
n = -28.5
