<u>Answer:</u>
<em>First Equation → </em><u><em>y = 21/4</em></u>
<em>Second Equation → </em><u><em>x = -1/57</em></u>
<u />
<u>Explanation:</u>
<em>solving equation #1</em>
<em></em>
step 1 - simplify
<em></em>

step 3 - multiply each side of the equation by six

step 4 - add three to both sides of the equation.

step 5 - add three y to both sides of the equation.

step 6 - simplify

step 7 - divide both sides of the equation by four

Therefore, the solution to the first given equation is <u><em>y = 21/4 </em></u><em>or y = 5.25.</em>

<em>solving equation #2</em>
<em />
step 1 - simplify.

step 2 - multiply each side of the equation by five.

step 3 - subtract twenty x from each side of the equation.

step 4 - divide each side of the equation by negative nineteen.

step 5 - switch

Therefore, the solution to the second equation is <em><u>x = -1/57.</u></em>

If you have a graphing calculator set it to radian mode and put these in there.
Here, we need to set up a proportion.
4.5 miles in 15 minutes.
In 75 minutes, how much miles can he ride?
4.5/15 = x/75
Cross multiply
4.5 * 75 = 337.5
15*x = 15x
15x = 337.5
15x/15 = 337.5/15
x= 22.5
Final answer:- Tommy can ride 22.5 miles in 75 minutes.
392 boots. If you divide everything into "sets" of an unknown amount, there are 5 more "sets" of boots than sandals, also known as the 245 boots. So if you divide 245 by 5, you'll get the number of items in a "set". Then just multiply by 8 from the 8:3 ratio. If you check it, it will come out to 392 boots to 147 sandals, which I think is ridiculous since sandals are supposed to come in pairs so you should never have a odd number. But anyway, 392 - 147 = 245
