Step-by-step explanation:
100% = 32
73% = 73×1% = 73×100%/100 = 73×32/100 = 23.36 pounds.
for an estimate I would round up to 75% = 3/4, and then calculate quickly 32 × 3/4 = 8×3 = 24 pounds.
Answer:
x = 0, y = -2
Step-by-step explanation:
-3x - 4y = 8 (1)
-4x - 3y=6 (2)
Multiply (1) by -4 and (2) by -3, we have:
12x + 16y = - 32 (3)
12x + 9y= -18 (4)
Subtract (4) from (3), we have:
(12x + 16y) - (12x + 9y) = - 32 - (-18)
<=> 7y = - 14
=> y = - 2
Replace y with - 2 in (3), we have x = 0
