if it would take billy an hour to race over to his girlfriends house and two hours if he went 20 miles per hour slower how far a

mel-nik [20]

Recall your d = rt, distance = rate * time.

now, let's say she lives "d" miles away, and so if Billy goes say at "r" mph fast to her house, he gets there in 1hr.

now, if he goes 20 mph slower, namely " r - 20 " mph, he gets there in 2 hours, same "d" miles.

$\bf \begin{array}{lccclll}
&\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\
&------&------&------\\
\textit{Billy}&d&r&1\\
\textit{slower Billy}&d&r-20&2
\end{array}
\\\\\\
\begin{cases}
d=r(1)\implies d=\boxed{r}\\
d=2(r-20)\\
----------\\
d=2\left( \boxed{d}-20 \right)
\end{cases}
\\\\\\
d=2d-40\implies 40=d$

Answer: x=

y+20

Step-by-step explanation

240=12x+8y

Step 1: Flip the equation.

12x+8y=240

Step 2: Add -8y to both sides.

12x+8y+−8y=240+−8y

12x=−8y+240

Step 3: Divide both sides by 12.

12x

The volume of dry goods like apple or peaches can be measured using bushels, pecks and quarts. A bushel contains 4 pecks and a p

Lisa [10]

Answer: $q= 32b$

Step-by-step explanation:

Given: A bushel contains 4 pecks and a peck contains 8 quarts.

i.e. A bush = 4 pecks

A peck = 8 quarts

Then, Number of quarts in 1 bush = 4 (8) =32

Let b = number of bushes and q = number of quarts

Number of quarts(q) in b bushes = 32b

hence, required equation: $q= 32b$ which describes the relationship between the number of b bushels and the number of q quarts.
