For dinner, jerry had a double cheeseburger and one order of medium fries totalalling 1200 calories. Joe has two double cheeseburgers and one medium fry totalling 1260 calories. How many callories are in one cheeseburger and medium frys

See explanation

Step-by-step explanation:

Let the number of callories that are in one cheeseburger be = x

Let the number of calories that are in one medium frys be = y

Therefore, the question can be formed into an expression as:

Jerry = 1x + 1y = 1200

Joe = 2x + 1y = 1260

x + y = 1200 i

2x + y = 1260 ok

Subtract equation i from ii

x = 60

Therefore, number of callories that are in one cheeseburger is 60 calories

Since x + y = 1200

60 + y = 1200

y = 1200 - 60

y = 1140 calories

The number of calories that are in one medium frys is 1140 calories

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
