Supplementary angles with measures (2x+3) and (3x+2)

1 answer:

8 0

2x + 3 + 3x + 2 = 180
5x + 5 = 180
subtract 5 from both sides
5x = 175
divide both sides by 5
x = 35

2(35) + 3 3(35) + 2
70 + 3 = 73 degrees 105 + 2 = 107 degrees

On Sunday, a local hamburger shop sold a combined total of 378 hamburgers and cheeseburgers. The number of cheeseburgers was sol

ipn [44]

Answer:

The number of hamburgers sold was 126.

Step-by-step explanation:

Let h = number of hamburgers sold

let c = cheeseburgers sold

c+h = 378

c = 2h

Substitute c =2h into c+h =278

c+h =378

2h+h = 378

Combine like terms

3h = 378

Divide by 3

3h/3 =378/3

h =126

The number of hamburgers sold was 126.
