Answer:

(1 gallon)/(100 ft^2)

Step-by-step explanation:

(1 gallon)/(100 ft^2) is a good conversion factor.  We could also use (100 ft^2)/(1 gallon), but I like the first, since the calculation is simpler:

(300ft^2)*/(1 gallon)/(100 ft^2) = 3 gallons  [I like multiplication better than division, and especially here, since 300/100 is 3, if my memory is correct.

Help me please I need an an answer asap

5A + 7 = 3A + 7 + 2A
We need to solve for A.

3A + 7 + 2A = 3A + 2A + 7 = 5A + 7 (We can add 3A and 2A because it's the same variable, so we add the coefficients)

5A + 7 = 3A + 7 + 2A
5A + 7 = 5A + 7

5A + 7 is always equal to 5A + 7 because it's the same equation. So the equation got infinitely many solutions.

Drew jumped farther than all 4 students above but jumped shorter than 7 feet , 7 inches. How far could drew have jumped? Write s
S_A_V [24]
<h3>The distance covered by Drew in long jump is either 7 ft 5 inches OR 7 ft  6 inches.</h3>

Step-by-step explanation:

Here, the needed table is attached for the reference.

Now, as we can see from the table:

The distance covered by  Cindy  = 2 yards, 1 foot 3 inches

The distance covered by  Tyrette   =  7 feet, 2 inches

The distance covered by Nina   =   2 yards, 1 foot, 1 inch

The distance covered by  Monique   = 7 feet, 4 inches

As we know : 1 yard  =  3 feet

So, the distance covered  by :

Cindy  =  2 yards, 1 foot 3 inches = 3 ft x (2)  + 1 ft +  3 in  = 7 ft 3 in

Tyrette   =  7 feet, 2 inches

Nina   =   2 yards, 1 foot, 1 inch  = = 3 ft x (2)  + 1 ft +  1 in  = 7 ft 1 in

Monique   = 7 feet, 4 inches

So by comparing all distances, we can see that:

The maximum distances jumped by all four  is 7 ft 4 inches.

The distance covered by Drew is less than 7 ft 7 in.

So, he must have jumped 7 ft 5 inches OR 7 ft  6 inches.

Hence, the distance covered by Drew in long jump is either 7 ft 5 inches OR 7 ft  6 inches.
