What’s this answer?
ANTONII [103]

Answer:

x=2, y=1

Step-by-step explanation:

The left and right sides are equal

7x-2 = 5x+2

Subtract 5x from each side

7x -5x-2 = 5x-5x+2

2x-2 = 2

Add 2 to each side

2x -2+2 = 2+2

2x = 4

Divide by 2

2x/2 = 4/2

x =2

The top and the bottom are the same length

6x+y = 7x-1

6(2) +y = 7(2)-1

12 +y = 14-1

Subtract 12 from each side

12 +y-12 = 13-12

y = 1

Suppose the cost of college tuition is expected to increase 5% every year. How much will the tuition at a comunity college cost
evablogger [386]

Answer:

$7,596.43

Step-by-step explanation:

The cost of the college tuition is increasing 5% compounded annually for 5 years.

∴ A = P(1 + r%)ⁿ

where A = tuition fee after 5 years.

           P = current tuition

           r = rate of increase

            n = period

A =  $5,952(1 + 5%)⁵

     = $5,952(1 + 0.05)⁵

     =  $5,952 × 1.05⁵

     = $7,596.43

    =
