Jessica has saved $50. She will add $25 to her savings each week. Ron has saved $40 and will add $25 to his savings each week. How much will each person have saved after 5 weeks?

Jessica will have saved $175, and Ron will have saved $165.

Step-by-step explanation:

Jessica starts out with $50. She adds $25 each week, and it's asking how much money she would have in 5 weeks. So, you multiply $25 by 5 to get $125. Then, you add $50 to that to get $175. Same thing for Ron. Multiply $25 by 5 to get $125, but this time add $40 to it to get $165.

Jessica- $175

Ron- $165

Step-by-step explanation:

Jessica starts with $50 so put that aside and then it says that she adds $25 EVERY WEEK so how much is she going to have in 5 weeks? 5 x $25 is $125 and now add the $50 which will equal $175

In Ron is the same thing but rather than adding $50 add $40 and it will equal $165

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
