-18a+17b is the answer because you multiply by -1 to each
Answer:
5/7
Step-by-step explanation:
You find a slope by using the equation y2-y1/x2-x1.
In this case: 15-5/21-7
10/14
5/7
Answer:
125
Step-by-step explanation:
5/4=x/100
x=500/4
x=125
Since we’ve been given a ratio, 3:8, we can convert that into a fraction and form an equation from it:
= 
The reason the numerator on the second fraction is 27/3 is because the team scored 27 points, not 27 baskets.
Simplify (Also replace the ? with an unknown variable):
= 
Cross multiply:
3*n = 9*8
Simplify:
3n = 72
Divide both sides by 3:
n = 24
The team had 33 three point tries, 9 successes, and 24 fails.
