Step-by-step explanation:
1. Yes he would be able to but the back pack and he would actually have 18 to spare. Explanation- he saves $9 a week so if he saves for 7 weeks then he will have $63 but since he only needed 45 he will have 18 to spare
2. Since they have 65.50 but need to have 180 then u could just subtract 180 from 65.50 so they would 114.5 more dollars

Step-by-step explanation:
2x + y = 1
2x - 2x + y = 1 - 2x
y = 1 - 2x
y = -2x + 1
4x + 2y = -1
4x + 2(-2x + 1) = -1
4x + 2(-2x) + 2(1) = -1
4x - 4x + 2 = -1
2 ≠ -1
The solution of the problem can't be a solution because they are both parallel lines, which means they have no solution.
Here for 120, the expression for the start root and end root is given
<h3>What will be the expression for start root and enroot of 120?</h3>
Here we need to find 
By simplifying the given expression, we get:
by taking square roots on both sides we get
Thus for 120, the expression for the start root and end root is given
