Mia is ordering 5 identical sandwiches and a bag of chips. The bag of chips costs $1.25, and the entire order costs $38.75. Write an equation you can use to find the price of a sandwich. Start by defining your variable. *

The equation that can be use to determine the price of a sandwich is 5x + $1.25 = $38.75

Step-by-step explanation:

The equation that can be use to determine the price of a sandwich is as follows:

Let us assume the price of a sandwich be x

So,

The equation would be

5x + $1.25 = $38.75

5x = $38.75 - $1.25

x = $37.5 ÷ 5

x = $7.5

hence, the equation that can be use to determine the price of a sandwich is 5x + $1.25 = $38.75

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

the first one, all those points on the line just make a strait line.
