Hello from MrBillDoesMath!
Answer:
The first choice ( -12, 20)
Discussion:
Using matrix multiplication we find the equations:
1x + 1y = 8 (A)
2x + 3y = 36 (B)
Next, compute
2(A) - B =>
(2x + 2y) - (2x + 3y) = 2*8 - 36 =>
(2x - 2x) + ( 2y-3y) = 16 - 36 =>
-y = -20 =>
y = 20
Substituting this y value in (A) gives
x + 20 = 8 =>
x = 8 - 20 =>
x = -12
The answer is the first choice ( -12, 20)
Thank you,
MrB
Answer:
x=1/4
Step-by-step explanation:
Answer:
you muliply first 9×7 and then carry the remainder to the other side and then 9×2 and add the remainder
Scenario B - 143 (Year 1), 109 (Year 2), 141 (Year 3)
In this scenario, the total income is 35,370. This is calculated by getting the sum of the number of garments in the span of three years and multiplying it by the rate of $90 per garment. Your income of 35,370 is lesser than your fixed cost for three years of 40,000.
It’s would be 4/25
