David will finish first, because if you divide Brad's miles by 2 to his miles in a 1/4 of an hour are 5.95 miles. This means David went 6.2 miles in the same time that Brad went 5.95. Therefore, David will finish first.

Virty [35]

Answer:

Here,

length = 8m

height = 4m

4s = 15 per m^2

The sum of 5 consecutive integers is 100. What is the first number in this sequence?
yanalaym [24]
So we can call first number "n"

Then all five integers would be n, n+1, n+2, n+3, n+4

So sum of them would be 5n + 10 = 100

Now you can solve for n:

5n + 10 = 100

5n = 90

n = 18

Verify: 18 + 19 + 20 + 21 + 22 = 100. All good.

So answer is 18

Katen [24]

Answer:

A.  v= $3,995.72 - $1,838.03

Step-by-step explanation:

Given:

fixed expenses: $1,838.03

total expenses: $3,995.72

We need to find the amount of Variable expense (v).

Now We know that;

Variable expense (v) can be calculated by Subtracting Fixed expense form Total expense.

framing in equation form we get;

Variable expense (v) = total expenses - fixed expenses.

Variable expense (v) = $3,995.72 - $1,838.03 = $2,157.69

Hence The equation represents Jessie's variable expense (v) = $3,995.72 - $1,838.03
