You have $60 and your sister has $120. you are saving $7 per week and your sister is saving $5 per week. how long will it take before you and your sister have the same amount of money and how much money will you each have?

x- number of weeks until the game is over.

60 + 7x = 120 + 5x ⇒ 7x - 5x = 120 - 60 ⇒ 2x = 60 ⇒ x = 30.

So, after 30 weeks,you and your sister have the same amount of money .

60 + 7·30 = 60 + 210 = 270 dollars,  will you each have

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !

Ithink it's the first one ( let me know if it right)
