For
ax+by=c
the slope is -a/b
the slope of paralell lines are the same
fidn slope
5x+3y=15
-a/b=-5/3
paralell as same slope
answer is A
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.
Step-by-step explanation:
The absolute value of 10-(-6.5) is 16.5, therefore the distance between the points is 16.5 units
It’s D
I did the work on a calculator and eliminated all the other answer choices.
