Mikaela travels 15 blocks on her skateboard in 5 minutes. at this speed, how many blocks can she travel on her skateboard in 12 minutes?

36 blocks

Step-by-step explanation:

It takes 5 minutes for 15 blocks.

It takes 12minutes for ? blocks.

Set it up with the minutes on top and blocks on bottom:

Cross multiply.

She skates 36 blocks in 12 minutes.

step-by-step explanation:

first, eliminate the parenthesis:

second, group like terms:

third, combine like terms:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
