Answer:
Step-50*t + 30*m = 1500, (1) (pounds)
4*t + 3*m = 138. (2) (cubic feet)
From (2), express 3m = 138 - 4t, and substitute it into (1). You will get
50t + 10*(138-4t) = 1500, or
10t = 1500 - 1380 ---> 10t = 1120 ---> t = 112 TVs.
From this point, find the number of microwaves on your own.
step by-step explanation:
The answer is 64 because you add 4 to both sides then you get 3/4w-1/2w=16 then you find like terms between 3/4w and 1/2w and it's 4 so you change 1/2 to 2/4 and then subtract 2/4w from 3/4w and you get 1/4w and that would make your equation 1/4w=16 then you divided by 1/4 which is multiplying by 4 and you get W=64
Answer:
L=25
W=10
Step-by-step explanation:
The statements expresses as
w <span>∝ b
where w = body's weight, b = amount of blood
Changing it into a direct variation becomes
w = kb or k = w/b
where k = proportionality constant
We know that k is obviously constant, we equation it into two states as
w</span>₁/b₁ = w₂/b₂
Given that w₁ = 160 lb, b₁ = 4.6 qt, b₂ = 175, w₂ = 175 lb. Then b₂ will be
160/4.6 = 175/b₂
b₂ = 160/(4.6*175) = 160/805 = 0.20 quarts
