21 feet = 3 inches (in a model)
84 feet = 12 inches (in a model)
84 ÷ 21 = 4
3 × 4 = 12
Answer:
c = 3 / a − b + 2
Explanation:
[ Step 1: Multiply both sides by c ]
ac = bc − 2c + 3
[ Step 2: Add -bc to both sides ]
ac + −bc = bc − 2c + 3 + −bc
ac − bc = −2c + 3
[ Step 3: Add 2c to both sides ]
ac − bc + 2c = −2c + 3 + 2c
ac − bc + 2c = 3
[ Step 4: Factor out variable c ]
c(a − b + 2) = 3
[ Step 5: Divide both sides by a - b + 2 ]
c(a − b + 2) / a − b + 2 = 3 / a − b + 2
c = 3 / a − b + 2

Answer:
18 kg
Step-by-step explanation:
We can use a proportion.
First, 13 kg 500 g = 13 kg + 500 g = 13 kg + 0.5 kg = 13.5 kg
Proportion:
9 cows is to 13.5 kg as 12 cows is to x
9/13.5 = 12/x
Cross multiply.
9x = 13.5 * 12
Divide both sides by 3.
3x = 4.5 * 12
Divide both sides by 3.
x = 1.5 * 12
x = 18
Answer: 18 kg
