Using a system of equations, it is found that a small box of tangerines costs $10 and a large box costs $14.
<h3>What is a system of equations?</h3>
- A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the <em>variables </em>are:
- Variable x: Cost of a small box.
- Variable y: Cost of a large box.
Krystal sold 7 small boxes of tangerines and 14 large boxes of tangerines for a total of $266, hence:
Simplifying by 7:
Mary sold 14 small boxes of tangerines and 3 large boxes of tangerines for a total of $182, hence:
Since :
Then
A small box of tangerines costs $10 and a large box costs $14.

Answer:
Step-by-step explanation:
4x-5+3x+5+40=180 degree(sum of interior angles of a triangle)
7x+40=180
7x=180-40
x=140/7
x=20
Answer: 0p + 40
Step-by-step explanation:
5p + 30 - 5p + 10
0p + 40
