Answer:
boys = 250
girls = 150
Step-by-step explanation:
5g = 3b eq. 1
g + b = 400 eq. 2
g = girls
b = boys
From the eq. 2
g = 400 - b
Replacing this last eq. on eq. 1:
5(400-b) = 3b
5*400 + 5*-b = 3b
2000 - 5b = 3b
2000 = 3b + 5b
2000 = 8b
2000/8 = b
250 = b
From eq. 2
g + 250 = 400
g = 400 - 250
g = 150
Check:
from eq. 1
5*150 = 3*250 = 750
The answer is 4733%

Ok so lets say D= Dog And C=Cat
D+C = 54
D = 8C
<span>
Now, substitute 8C for D in the first equation to get: </span>
<span>8C + C = 54 </span>
<span>Solving for the cat gives us C = 6 </span>
<span>D = 8 x 6 = 48
</span>Dog Weighs 48 Pounds
Answer:
2 × h
Step-by-step explanation:
h = b ÷ 2 (multiply both sides by 2)
2 × h = b ÷ 2 × 2
2 × h = b
b = 2 × h
