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.

3 is B
4 is D
I can figure out 5, Im kinda bad at plotting.
Volume formula length x width x height .
Answer:
(x,y)=(2,12).
Step-by-step explanation:
Let's find the answer using the given equations:
y1=5x+2
y2=-3x+18
Using the intersection method:
y1=y2 so:
5x+2=-3x+18
5x+3x=18-2
x=16/8=2
Using x=2 in the first equation we have:
y1=5*(2)+2=12
So, the answer is (x,y)=(2,12).
Let's check our answer:
y1=5x+2
12=5*(2)+2
12=12
y2=-3x+18
12=-3*(2)+18
12=12
Answer:
3/8 = 9/24 ; 1/3 = 8/24 ; 3/8 > 1/3
Step-by-step explanation:
You have to multiply 8 and 3 to obtein the same number as denominatoe (24).
Once you have the same number you can use < = >
