Answer:
10% of 250 = 25.
When getting an increase, (using ^ for this example) add 25 to 250, getting 275. That's one increase of 10%. For an increase of 5 years (x = 5) divide 250/10=25, then multiply 25x5=125. That is the increase number. Add 125+250=375. Y=375
X = 5, Y = 375
Answer:
10 miles
Step-by-step explanation:
3+1x=13
Minus 3 from both sides.
3-3+1x=13-3
1x=10
Then divide both sides by 1.
1x/1=10/1
x=10
That equation means that John started with $107 in his bank account and is making $2 dollars a day. The correct equation is y=107x+2.
Answer:

Step-by-step explanation:
The starting number must always be in the ones' place, it cannot be in the tens place. And it must be between 1 and 10.
X - y = 3
6x + 4y = 13
x = y + 3
6(y + 3) + 4y = 13
6y + 18 + 4y = 13
10y = 13 - 18
10y = - 5
y = - 5/10
y = - 1/2
x = - 1/2 + 3
x = - 1/2 + 6/2
x = 5/2
