Answer:

18,060

Step-by-step explanation:

0.86 kilometers is the same as 860 meters. If he swam 860 meters a day for twenty-one days, (860 times 21) he'd end up with 18,060 meters in total.

(That's about 722 1/2 lengths of a pool, but you didn't need to know that :P )

Which line has an y-intercept of -2
DiKsa [7]
The y-intercept is found when x is set to 0.

Set x to equal 0 for both equations:

3(0) - 2y = -6
-2y = -6

Divide both sides by -2:

y = 3

The y-intercept of this equation is 3, so the first line does not have the y-intercept of -2.

-
0 + 2y = -2
2y = -2

Divide both sides by 2:

y = -1

The y-intercept of this equation is -1, so the second line does not have the y-intercept of -2.

Neither line has a y-intercept of -2.

You buy two T-shirts and I say oh you pay the full price of $12 for the first T-shirt and you get the second T-shirt for have th
Komok [63]
Answer: You paid 3/4 of the full price.

Explanation: Total cost of the two shirts = shirt one ($12) + shirt two (half price, so $6) or $18 all together. If you had paid full price for both shirts, it would have cost you $24, or $12 times 2. 24 - 18 = 6, so you saved six dollars. 24 (full price) divided by 6 = 4, so we know that $6 is 1/4 of the full price. Because of this, we know that the amount you spent ($18) was 3/4 of the full price, since 4/4 (total) - 1/4 (amount saved) = 3/4 (amount spent). Another way to solve this is to simply divide 18 by 24.
