Step-by-step explanation:
To solve this system of equations, let's first add the equations together:
There are no values of 
that will make this equation true, so the lines never intersect, and therefore there are no solutions to this system of equations.
Answer:
I think the answer is C if I'm wrong sorry its been two years since i last learnt this
Step-by-step explanation:
The answer is 0.11 as a decimal.
The have been saving for 10 weeks.
Given:
Duane = $5 every other week. meaning every 2 weeks
Mick = $2 every week
Amount Saved = $45
First, divide Duane's $5 by 2 to get his weekly contribution.
$5/2 = $2.50
let x be the number of weeks.
Duane + Mick = $45
2.50x + 2x = 45
4.50x = 45
4.50x/4.50 = 45/4.50
x = 10 weeks
to check:
2.50x + 2x = 45
2.50(10) + 2(10) = 45
25 + 20 = 45
45 = 45
