Julia is saving money for the down payment on a car. She plans to save for one year. Her parents have offered to contribute $50
denis23 [38]

Answer:

12x+600=2700

$175

Step-by-step explanation:

Let x represent money saved by her in one month.

So money saved by her in one year (12 months) would be 12x.

We can represent our given information as:

12x+600=2700\\12x=2700-600\\12x=2100\\x=\frac{2100}{12}\\x=175

Therefore, she needs to save $175 per month.

Evaluate 5k + 1 when: *
wlad13 [49]

1

k^2 = 4k

k = 0, k = 4

#2

k^2 - 5k = k + 7

k^2 - 6k = 7

k^2 - 6k + 9 = 16

k - 3 = 4 ⇒ k = 7

k - 3 = -4 ⇒ k = -1

#3

k^3 - 5k^2 + 3k = -k

k^3 - 5k^2 + 4k = 0

k(k^2 - 5k + 4) = 0

k = 0, k = 1, k = 4

#4

|k + 1| + 2 = 8

|k + 1| = 6

k = 5, k = -7

DedPeter [7]

Answer:

No

Step-by-step explanation:

You cannot work negative 3 hours, it's impossible. One possible solution would be to work 50 hours a week at dog walking for 7 dollars an hour, and 10 hours a week at Computers & More, Inc. for 12 dollars a week. This would give you 350 dollars from dog walking, and 120 dollars from Computers & More, Inc. This would be a total of 470 dollars.
