Answer:
8 pounds of cheaper candy,
17.5 pounds of expensive candy
Step-by-step explanation:
Let's define some variables. Let's say the amount of pounds of candy that sells for $2.20/lb is x, and the $7.30 is y. Now we can write some equations!
x + y = 25.5
We can start substitution. We can say that x = 25.5 - y. Plugging this into our second equation, we get:
y = 17.5
Plugging this in, we find that:
x = 8.
1. 4x − 2y = 10 and 2x − y = 5
Lines are coincident.
2. y = 2x − 3 and −2x + y = −5
Lines are parallel.
3. 2x − 5y = 14 and 3x + 4y = 10
Lines are intersecting.
<h2>Linear system</h2>It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
<h3>Given</h3>1. 4x − 2y = 10 and 2x − y = 5
