Answer:
1/8(A)+(3/4)(168A)=76 is an equation to find the mass of A, the mass of A is 80 grams.
Stepbystep explanation:
What do we know?
Both sacks together are 168 grams. Therefore;
A+B=168
One eighth of sack A and three quarters of sack B is equal to 76 grams. Therefore;
1/8(A)+(3/4)B=76
Let's solve using the substitution method to find A. First, we need to isolate and then substitute B for an expression containing A.
A+B=168
B=168A
Now that we have isolated B, we can substitute '160A' for B in the other equation.
1/8(A)+(3/4)(168A)=76
1/8(A)3/4(A)+126=76
1/8(A)3/4(A)+126=50
5/8(A)=50
A=80
