Answer:

Step-by-step explanation:

<u><em>Blue Car:</em></u>  (31 1/2 miles)/(1 1/4 gallons)

(63/2) miles / (5/4) gallons

(63/2)*(4/5) = <u>25.2 miles/gallon.</u>

<u><em>Red Car:</em></u>  (27 1/5 miles)/(4/5 gallon)

= <u>34 miles/gallon.</u>

The Red Car will travel the furthest.

Art [367]

Answer:

17 \le t \le 28

Step-by-step explanation:

Given

t = 22\frac{1}{2} --- average time

\triangle t = 5\frac{1}{2} --- the variation

Required

The inequality to represent the scenario

To do this, we simply add and subtract the variation from the average time.

i.e.

t \± \triangle t

So, the inequality is:

22\frac{1}{2} - 5\frac{1}{2} \le t \le 22\frac{1}{2} + 5\frac{1}{2}

Solve:

17 \le t \le 28

a_sh-v [17]

Answer:

1 4/5 miles :)

Step-by-step explanation:

We first need to get them at a common denominator :)

4 1/2 = 4 5/10

2 3/5 = 2 6/10

Now we subtract :)

4 5/10 = 3 14/10

3 14/10 - 2 6/10 = 1 8/10 = 1 4/5

Have an amazing day!!

Drag and drop numbers into the boxes so that the paired values are in a proportional relationship.
Nezavi [6.7K]
It looks like every x value divided by 5 will result in the y value. For the "x" section, the third one would be 10 because 10/5=2. For the last box in the "y" section, the answer would be 5 because 25/5=5.
