Answer:
Step-by-step explanation:
3/3y=y/2y
3y=6
y=2
22.5/90*100%=0.25*100%=25%
16a³b = 8ab(2a²)
24ab² = 8ab(3b)
Lowest Common Multiple = (8ab)(2a²)(3b) = 48a³b²
6a³b x 3b = 48a³b²
24ab² x 2a² = 48a³b²

Answer:
y=x/2+5/2
Step-by-step explanation:
4=1/2(3)+5/2
y=×/2+5/2
Given :
An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 g of an alloy containing 12% copper with 78 g of an alloy containing 92% copper.
To Find :
How many grams of copper are in the resulting mixture what percentage of the resulting mixture is copper.
Solution :
Mass of copper in 50 gm alloy =
.
Mass of copper in 78 gm alloy =
.
Total mass of copper, ( 6 + 76.44 ) gm = 82.44 gram.
Percentage of copper in resulting mixture :

Hence, this is the required solution.
