19) Jason received an Amazon gift card for his birthday. After he buys a song, the card's value is $17.21. After he purchases a second song, the card is worth $14.42. Jason downloads one more song and has $11.63 left on the card. i) Write an equation to define a as the amount of money left on the gift card after n purchases. ii) Jason plans to download a song every Tuesday moming. How many weeks in a row can he buy a song before the gift card runs out?​

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

answer:

c 60% on edg

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
