Jim drove 168 miles in 4hr. If he can keep the same pace, how long will it take him to drive 504 miles

Since he went 168 miles in 4 hours, then his speed is 42 mph. Then, 504 divided by 42 is 12. It will take 12 hours at a steady pace of 42 mph to reach 504 miles.

Hi there.

First, we want to find out how many miles Jim can travel in one hour.

168 ÷ 4 = 42 mph

Now, we take 504 and divide it by the amount he can drive in one hour.

504 ÷ 42 = 12

It will take Jim 12 hours to drive 504 miles.

Set up a system of linear equations, and then solve for the indicated quantities.

hichkok12 [17]

9514 1404 393

Answer:

smaller: -4
larger: -1

Step-by-step explanation:

Substituting the given variables into the word problem, we have two equations:

3x +3y = -15

6x -3y = -21

Adding these equations eliminates y:

9x = -36

x = -4 . . . . divide by 9

Using this in the first equation, we have ...

3(-4) +3y = -15

-4 +y = -5 . . . . . divide by 3

y = -1 . . . . . . . . . add 4

The smaller number is -4; the larger is -1.

The rectangle below has a area x^2-x-72 square meters and a length of x+8 meters what expression represents the width of the rec

mixer [17]

ANSWER

$w = (x - 8)$

EXPLANATION

The given rectangle has area,

$A = {x}^{2} - x - 72 \: {m}^{2}$

It was given to us that, the length of the rectangle is l=(x+8)

To find the width, we need to factor, the expression for the area.

We split the middle term to get,

$A = {x}^{2} - 9x + 8x- 72$

We now factor by grouping;

$A = x(x - 9) + 8(x- 9)$

$A = (x + 8)(x - 9)$

We know that area of a rectangle is

$A = l \times w$

Hence the width of the rectangle is,

$w = (x - 8)$

-2(2u-3)+3u=3(u+8)<br> u=?

If you expand this equation first
You get -4u+6+3u=3u+24

And if you simplify that you get:
-u+6=3u+24
Now you need to solve this equation to find u

First bring 3u to the other side to -u-3u (the positive changes to negative)
Now the equation is
-4u+6= 24
Take 6 of both sides
-4u=24-6= 18
-4u= 18
So u= -18/4
Which simplifies to -9/2

Answer: -9/2

Murrr4er [49]

Answer:

$43,512

Step-by-step explanation:

3.6% = 0.036

0.036 * 42,000 = 1,512

42,000 + 1,512 = 43,512
