X songs
Y games

A) 8X + 3Y = 20.50
B) 4X + 5Y = 22.50

Multiplying equation B) by -2
B) -8X -10Y = -45.00  then adding this to
A) 8X + 3Y = 20.50  we get

x = 1st consecutive even number

x + 2 = 2nd consecutive even number  

x + x + 2 = 22

2x + 2 = 22

2x = 20

x = 10

x + 2 = 12

10 and 12 are the two consecutive even numbers

Marissa bought a skirt on sale for $8.45 less that 60% off the original price. She paid $9.55 for the skirt. What was the origin
nadya68 [22]

Answer:

$23.88

Step-by-step explanation:

Represent the original price by p.  

The sale price is (100% - 60%), or 40%, of p:  

$9.55 = 0.40p

Dividing both sides by 0.40 results in:

p = $23.88 (rounded up from $23.875).
