A new house costs $260,000.00. Sara wants to buy the house and needs $35,560.00 for a down payment. Sara currently has $28,000.00 in a savings account that earns 9% simple interest. How long must she keep the money in the savings account in order to have enough for the down payment on the house?

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,

mrb

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

2nd one in the first row is correct

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
