So we have 2 variables here: tacos and orders of nachos.
When we translate the paragraphs into equation:
Now, in this situation we can make use the elimination method by converting 3n to -27n.
Add both equations:
So we find that one taco costs $2.75.
We can plug this into any of the first two equations to find n:
So one order of nachos cost $1.40.

We get x is 10°. So angle A is 50°, angle B is 46°, and angle C is 84°.
Step-by-step explanation:
Step 1:
The sum of all the angles for a straight line is 180°. So the sum of the three given angles is 180°.
The angles are ,
and
So
So x = 10°.
Step 2:
Angle A Angle A is an acute angle.
Angle B Angle B is an acute angle.
Angle C Angle C is also an acute angle.
