You can jog around the block twice and the park once in 10 min. You can jog around the block twice and the park 3 times in 22 mi

stich3 [128]

B = block p = park

2b + p = 10 min 2 runs around the block takes 10 minutes
2b + 3p = 22 min 2 runs around the block plus 3 runs around the park takes 22 minutes

To solve, I will use substitution. First, I will divide the first equation by 2 to get b by itself and subtract p from both sides to get b by itself. Then, substitute 5 - 1/2p in for b in the second equation because they have equal values. Then, subtract 10 from both sides to eliminate it. Divide by 2 to both sides to get 'p' by itself.

2b + p = 10 min ---------→b + 1/2p = 5 ----------→ b = 5 - 1/2p

2(5 - 1/2p) + 3p = 22 ---------→ 10 -p + 3p = 22 --------→ 10 + 2p = 22

10 + 3p = 22 ----------→ 2p = 12

2p = 12 -------------→ p = 6

It takes 6 minutes to jog around the park

Hope this helps!

Kareem rented a truck for one day. There was a base fee of $14.95 , and there was an additional charge of 93 cents for each mile

allochka39001 [22]

Answer:

He drive the truck <u>292</u> miles.

Step-by-step explanation:

Given:

Kareem rented a truck for one day.

There was a base fee of $14.95, and there was an additional charge of 93 cents for each mile driven.

Kareem had to pay $286.51 when he returned the truck.

Now, to find the miles he drive the truck.

So, we deduct the base fee first:

$286.51 - $14.95 = $271.56.

So, the remaining amount = $271.56

Now, we divide the remaining amount by by charge of 93 cents for each mile driven:

Converting cents into $ = 93 cents = 93 ÷ 100 = $0.93.

$\$271.56\div \$0.93$

$=292\ miles.$

Therefore, he drive the truck 292 miles.

About Slope Intercept Form:

y = mx + b
m is the slope
b represents the y-intercept

For the graphing one, since the slope is positive, you have to go up 5 and right 2 because the slope equals <u>rise</u>

run.

5 represents rise & 2 represents run. Then -4 is the starting point, the y-intercept.

Hope this info helps!! :)
