<span>1. The problem says that the is ratio 1:3:5 by weight and Talil wants to make 180 kg of concrete mix.

 2. Therefore, you have:

 1+3+5=9

 180 kg/9=20 kg

 3. Each of the 9 parts of the ratio weights 20 kg. So, to make 180 kg of concrete mix, he needs:

 1x20 kg=20 kg of cement
 3x20 kg=60 kg of sand
 5x20 kg=100 kg of gravel

 4. Talil has:

 15kg of cement (Not enough)
 85kg of sand (More than enough)
 100kg of gravel (Enough)
</span><span>

Consider the following equation, bh+hr=25 when solving for r
Komok [63]
Solve for r.

You want to get r by itself on one side on the equal sign.

bh + hr = 25

Subtract bh from both sides.

hr = 25 - bh

Divide h on both sides.

r = 25 - bh / h

The two h's cancel each other out.

r = 25 - b

Hope this helps!
