Let's set up a proportion. (<em>We will call our answer x.</em>)
15 cookies / 9 dollars = 1 cookie / x dollars
15x = 9
x = 9/15 dollars
x = 60 cents
Answer:
D. y = 4x + 9
Step-by-step explanation:
a line that passes through the point (-2, 1) and has a slope of 4
y = 4x + b
b = y - 4x
b = 1 - 4(-2)
b = 1 + 8
b = 9
So equation
y = 4x + 9
Answer: 9
Step-by-step explanation:
Since p is the number of homework problems April has. Since Nancy has 2 more than twice the number of homework problems April has and has 20 homework problems, this can be expressed into an equation as:
(2 × p) + 2 = 20
2p + 2 = 20
2p = 20 - 2
2p = 18
p = 18/2
p = 9
April has 9 homeworks, therefore p is 9.
