Answer:

x =20

Step-by-step explanation:

We can use proportions to solve

$240         320

----------- = ------------

15                x

Using cross products

240x = 320 * 15

240x =4800

Divide by 240 on each side

240x/240 = 4800/240

x =20

X+5(x-1)=(x-3)4-1 anyone?
Troyanec [42]
Hi there!

First of all simplify x+5(x-1)=(x-3)4-1.
This would make 6x-5=4x-13.

Next, subtract 4x from both sides.
6x-5-4x=4x-13-4x
2x-5=-13

Then add 5 to both sides.
2x-5+5=-13+5
2x=-8

Finally divide by 2 on both sides.
2x/2=-8/2
x=-4

Your answer is -4.

Hope this helped!

A team of explorers going to South Pole expect to travel 1014.15km in total the team expect their average sped for expidition n
Paul [167]

It will take them about 26 days to complete the expedition

<h2>Proportion and distance</h2>

According to the information, the team of explorers is to travel 19.12km in 12 hours

  • 19.12 km  = 12 hours

If they are expected to travel 1014.15km in total, the total time taken is given as:

1014.15km = x

Take their proportions:

\frac{19.12}{1014.15} = \frac{12}{x} \\&#10;19.12x = 12,169.8\\&#10;x = 636.495hours

Convert the time taken to days;

x =\frac{636.495}{24}\\&#10; x \approx 26.5 days

This shows that it will take them about 26 days to complete the expidition.
