Two numbers have a sum of 49. If one number is x, express the other number in terms of x

y = 49 - x

Step-by-step explanation:

Let the other number be y.

Given x + y = 49

x+y-x = 49 - x

y = 49 - x

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
