Keli bought 19 apples of 2 varieties to make a pie the total cost of apples cost 0.25 each and gala apples cost 0.30 each how much of each did keli buy?

y=7 and x=12

Step-by-step explanation:

X= number of Granny Smith apples

Y= number of Gala apples

With the given data we build and solve the following system

x+y=19

0.25x+0.3y=5.10

So we conclude that  

y=7 and x=12

Brainliest please Your welcome

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
