The mass of two sacks of potatoes is 168 grams. one-eight of the mass of sack a and three-quarter of the mass of sack b is 76 grams. write an equation to find the mass of sack a.

1/8(A)+(3/4)(168-A)=76 is an equation to find the mass of A, the mass of A is 80 grams.

Step-by-step 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=168-A

Now that we have isolated B, we can substitute '160-A' for B in the other equation.

1/8(A)+(3/4)(168-A)=76

1/8(A)-3/4(A)+126=76

1/8(A)-3/4(A)+126=-50

-5/8(A)=-50

A=80

step-by-step explanation:

you have to multiply 1.53 by 12 so the equation is 12x1.53 and then that is your answer.

where did you get them? if you picked from the grass, is is probably poisonous.
