Answer:
B: 1 to 5
Step-by-step explanation:
3 hours is to 15 miles as 1 hour is to 5 miles (division by 3)
Answer:
![y=30x+45](https://tex.z-dn.net/?f=y%3D30x%2B45)
Step-by-step explanation:
Let
x ----> the number of hours
y ----> the cost in dollars
we know that
The linear equation in slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where'
m is the slope or unit rate
b is the y-intercept of initial value
In this problem
we have
The slope is equal to
![m=\$30\ per\ hour](https://tex.z-dn.net/?f=m%3D%5C%2430%5C%20per%5C%20hour)
The y-intercept or initial value is equal to
![b=\$45](https://tex.z-dn.net/?f=b%3D%5C%2445)
therefore
The linear equation in slope intercept form is equal to
![y=30x+45](https://tex.z-dn.net/?f=y%3D30x%2B45)
Simple...
you have:
RS=15
RT=18
If you're trying to find ST....
RT-RS=ST
In math..( xD)...
18-15=3
ST=3
Thus, your answer.
Answer choices:
A. a car
B. a set of rectangular stairs
C. a rolling pin
D. a stapler
The answer is C. a rolling pin
