Answer:
slope = 3
Step-by-step explanation:
Choose any two points: For example, (2, 4) and (4, 10)
Find the difference in y. This is called the "rise."
rise = 10 - 4 = 6
In the same order, find the difference in x. this is called the "run."
run = 4 - 2 = 2
slope = rise/run
slope = 6/2
slope = 3
Answer:
3 3/4 teaspoons
Step-by-step explanation:
Pedro mixes 3/4 teaspoon of plant food into each gallon of water. How many teaspoons of plant food should Pedro mix into 5 gallons of water? To answer this, multiply "3/4 teaspoon per gallon" by 5 gallons:
3 teaspoons
------------------- * 5 gallons = 15/4 teaspoons, or 3 3/4 teaspoons.
4 gallons
A+30 = 60
a = 30
a + 2b = 60
30+2b = 60
2b = 30
b = 15
5b - 5c = 60
5(15) - 5c = 60
5c = 15
c = 3
10c + d = 60
10(3) + d = 60
30 + d = 60
d = 30
2d + 6e = 180 - 60
2(30) + 6e = 120
6e = 60
e = 10
4f + 4e = 120
4f + 4(10) = 120
4f = 80
f = 20
