There are 110 calories per 28.4 grams of cereal x. find how many calories are in 42.6 grams of this cereal

If there is 110 calories per 28.4 grams of cereal -- grams will be  

It would be 110/28.4=x

3.87 calories a gram.  

3.87*42.6=164.86  

164.86 calories in 42.6 grams of cereal

the answer will be

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
