Jacob walked for x miles and then cycled for y miles between his home and the library. the number of miles jacob cycled was 3 miles more than twice the number of miles he walked. the total number of miles jacob walked and cycled was 6 miles. which graph best shows the number of miles jacob walked and cycled?

Graph of lines y equals 2 x plus 3 and y equals minus x plus 6. Lines intersect at ordered pair (1, 5)

Step-by-step explanation:

Here x represents the miles walked by Jacob and y represents the miles for which Jacob cycled.

Thus, the total distance covered by Jacob = x + y

But according to the question,

The total number of miles Jacob walked and cycled was 6 miles.

Therefore,  x + y = 6  -------(1)

Also, The number of miles Jacob cycled was 3 miles more than twice the number of miles he walked.

That is, y = 2x + 3 ----------(2)

subtracting equation (2) from equation (1),

We get,

x = 6 - 2x - 3

⇒ x+2x = 6-3   ( by adding 2x both sides)

⇒ 3 x = 3

⇒ x = 1

Put the value of x in equation (1)

We get y = 5

Thus, Jacob walked 1 miles

And, he cycled 5 miles.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
