Step-by-step explanation:
Answer: it would take 20 weeks before the amount in both accounts would be the same.
Step-by-step explanation:
Let x represent the number of weeks that it will take either Ruben and Shawna to have the same amount of money in their account.
Let y represent the total amount that would be in Shawna's account after x weeks
Let z represent the total amount that would be in Ruben's account after x weeks
Shawna has $750 in the bank. She deposits $37.50 each week. This means that the total amount after x weeks would be
y = 37.5x + 750
Ruben has $850 in the bank. He deposits his paycheck of $102.75 every Monday,and he spends about $70.25 each week.. This means that the total amount after x weeks would be
z = 850 + 102.75x - 70.25x
z = 850 + 32.5x
To determine the number of weeks before the amount in both accounts will becomes the same, we would equate y to z. It becomes
37.5x + 750= 850 + 32.5x
37.5x - 32.5x = 850 - 750
5x = 100
x = 100/5 = 20
Answer:
25
Step-by-step explanation:
divide 14 from 350.
Answer: x=4, y=1
Step-by-step explanation:
Because y=y, you can make an equation that is -x+5=2x-7. Then add the x to the right side, so it would be 5=3x-7. Then add the 7 to the left side to get all of the numbers in one place. So it would be 12=3x. Divide by 3 on both sides and you get x=4. Then plug x into either one of the original equations. Both equations should get you the same answer for y. Y=-4+5. Y=1. And the other equation. Y=2x-7, y=8-7. Y=1
