Answer:
p = (2h-W)/-3
Step-by-step explanation:
2h - W = -3p
divide both sides by -3
(2h-W)/-3 = p
Answer:
$18500 at 6% and $28500 at 8%
Step-by-step explanation:
Let x represent the amount invested at 6%. Then x+10000 is the amount invested at 8%. The total income from the two investments is the sum of the products of the amount invested and the interest rate:
x·6% +(x+10000)·8% = 3390
0.14x + 800 = 3390 . . . . . . . . collect terms
0.14x = 2590 . . . . . . . . . . . . . .subtract 800
2590/0.14 = x = 18500 . . . . . divide by the coefficient of x
Sue has invested $18500 at 6% and $28500 at 8%.
The question lacks the total number of socks and belts altogether. Thsi value is necessary so that we can create another equation to solve the unknowns.
if assumed that a = b, the answer, a = b = 2.43 will not make sense since you cannot buy 43% of a pair of socks. Completely define the conditions so that the answer can be obtained.
by trial and error, 3 pair of socks and 2 belts would be a sensible answer
(3/5)^2 + 4 × 3 - 2
9/25 + 12 - 2
9/25 + 10
It would be 10 and 9 over 25
I think the answer is C-No solutions
