erry. The number of chocolate cupcakes is eighteen more than twice the number of strawberry cupcakes. Which system of equations can be used to find the number of chocolate cupcakes, c, and the number of strawberry cupcakes, s? A. c + s = 180 s = 2c - 18 B. c + s = 180 c = 2s + 18 C. c - s = 180 s = 2c + 18 D. c = 2s c - 180 = s

Let s be the number of strawberry cupcakes, and c the number of chocolate cupcakes.
From our problem we know that the total number of cupcakes is  180, so c+s=180. We also know that the number of chocolate cupcakes is eighteen more than twice the number of strawberry cupcakes, so c-18=2s, or solving for c: c=2s+18.
Know we have our system of equations:
\left \{ {{c+s=180} \atop {c=2s+18}} \right.
We can conclude that the correct answer is <span>B. c + s = 180 c = 2s + 18.

Lets solve our equations to find how many cupcakes of each they have:
from our second equation we know that </span>c=2s+18; lets replace that value in our first equation to find the number of strawberry cupcakes:
2s+18+2=180
3s=162
s= \frac{162}{3}
s=54
<span>Now that we know the number of strawberry cupcakes, lets replace that value in our second equation to find the number of chocolate cupcakes:
</span>c=2(54)+18
c=108+18
c=126
As a bonus, we can conclude that the <span>math club have 126 chocolate cupcakes and 54 strawberry cupcakes. </span>

The correct answer is B) c+s=180, c=2s+18

The number of chocolate and strawberry together make 180.  c+s=180.

The number of chocolate is 18 more than twice the number of strawberry; c=2s+18.

Which of the following equations represents a line that passes through the points ( − 3 , − 3 ) and (−2,0)?
jek_recluse [69]

y=3x+6

Use

y=mx+b

to calculate the equation of the line, where

m

represents the slope and

b

represents the y-intercept.

Slope is equal to the change in

y

over the change in

x

, or rise over run.
