Essentially, what we're looking at here are two alternate interior angles.

Wait. What? Alternate interior angles?

It sounds like some super fancy math jargon, but it's a fairly simple concept that I'll try my best to explain. First, let's look at lines L and M as two parallel lines, meaning that these two are lines with equal slopes, and will never intersect. See that line that goes in between the parallel lines L and M? That's called a transversal. It's basically a line that goes through two parallel lines.

Now we know that there's a transversal going through the parallel lines. So what? Well, there's a couple of special attributes to transversals. See the two angles, 7x-7 and 4x+14? As you can tell, these two angles alternate in the interior space between the transversal and the parallel lines.

Alternate interior angles are equal. There's a way to prove that they're equal, but I won't bore you with the specifics since that's not what the question's asking.

If the angles need to be equal for lines L and M to be parallel, we can make an equation that'll solve for x:

7x - 7 = 4x + 14

<u>Subtract 4x from both sides:</u>

7x - 4 x - 7 = 4x - 4x + 14

3x - 7 = 14

<u>Add 7 to both sides:</u>

3x - 7 + 7 = 14 + 7

3x = 21

<u>Divide both sides by 3 to completely isolate x:</u>

\frac{3x}{3} = \frac{21}{3}

x = 7

And that's our answer! If you need me to explain anything any further, just ask!

A jar containing only dimes and quarters contains a total of 54 coins. The value of all the coins in the jar is $9.15. Solve by
Paladinen [302]

Answer: the jar contains 29 dimes and 25 quarters.

Step-by-step explanation:

The worth of a dime is 10 cents. Converting to dollars, it becomes

10/100 = $0.1

The worth of a quarters is 25 cents. Converting to dollars, it becomes

25/100 = $0.25

Let x represent the number of dimes contained in the jar.

Let y represent the number of quarters contained in the jar.

A jar containing only dimes and quarters contains a total of 54 coins.. This means that

x + y = 54

The value of all the coins in the jar is $9.15. This means that

0.1x + 0.25y = 9.15 - - - - - - - - - - - 1

Substituting x = 54 - y into equation 1, it becomes

0.1(54 - y) + 0.25y = 9.15

5.4 - 0.1y + 0.25y = 9.15

- 0.1y + 0.25y = 9.15 - 5.4

0.15y = 3.75

y = 3.75/0.15 = 25

x = 54 - y = 54 - 25

x = 29

4*10^6 is how many times as large as 1*10^4?
maxonik [38]
So you want to know how many times  4*10^6 fits inside 1*10^4, if so, here's the answer:

First we see that 4*10^6 is equal to <span>4,000,000, and</span> 1*10^4 is equal to 10,000.

Then we divide \frac{4,000,000}{10,000}, and we get 400, so.

The answer is 400.

Hope this helped! c:

Jesse bought a car for $25,000. The car depreciates approximately 10% of its value each year. What will the car be worth in 5 ye
givi [52]

Answer:

$12,500

Step-by-step explanation:

I got this answer by first taking the purchase price of the car and multiplying it by .10 to see what ten percent of the price was and I got $2,500. Then I took and multiplied 2,500 by 5 years and go 12,500. Then I subtracted 12,500 from the original purchase price to get $12,500. Meaning that the value of the care has decreased by half of the purchase price.

HOPE THIS HELPS!
