So we have 2 variables here: tacos and orders of nachos.

When we translate the paragraphs into equation: 28t + 27n = 114.80 \\ \\ 12t + 3n = 37.20

Now, in this situation we can make use the elimination method by converting 3n to -27n.

- 108t - 27n = - 334.8

Add both equations: 28t + 27n - 108t - 27n = 114.8 - 334.8 \\ \\ - 80t = - 220 \\ \\ t = 2.75

So we find that one taco costs $2.75.

We can plug this into any of the first two equations to find n: 12 \times 2.75 + 3n = 37.2 \\ \\ 33 + 3n = 37.2 \\ \\ 3n = 4.2 \\ \\ n = 1.4

So one order of nachos cost $1.40.

What is 7 plus the sum of m and -17​
olasank [31]

Answer:

m - 10

Step-by-step explanation:

7 plus = 7 +

The sum of m and -17 = m + (-17)

7 + (m + -17)

We can get rid of the parentheses

7 + m + -17

Combine like terms

7 + -17 = -10

m + -10

Get rid of the addition sign

m - 10
