Answer:
1.625
Step-by-step explanation:
Add 13 to both sides
8n = 26 - 8n
Add 8n to both sides
16n = 26
Divide both sides by 16
Your answer is 1.625

Answer: B. Parallel</h3>
============================================================
Explanation:
Solve each equation for y. In other words, get y by itself
Let's start with the first equation
-3x = 3 - y
-3x - 3 = -y
-y = -3x-3
y = 3x+3
Do the same for the second equation
-1+y = 3x-2
y = 3x-2+1
y = 3x-1
The two equations we got were
y = 3x+3
y = 3x-1
Both have the same slope (m = 3) but different y intercepts, so we have parallel lines here.
Answer:
$60
Step-by-step explanation:
John's Money = $2000
Annual Interest Rate = 6%
Total amount John should
receive after a year = 2000x(1+0.06)
= 2120
Total interest amount in a year = 2120 - 2000
= $120
Total interest amount in a per month = 120/12 = $10
Total interest amount in 6 months = 10 x 6 = $60
-7x + 4y = -6
2x - 5y= 21
<u>Make it so x's are equal</u>
-14x + 8y = -12
-14x - 40y = 147
<u>Subtract</u>
-32y = -169
<u>Divide</u>
y = 5.28125
<u>Plug in the y value</u>
2x - 5(5.28125) = 21
<u>Simplify</u>
2x -26.40625 = 21
<u>Add</u>
2x = 47.40625
<u>Divide</u>
x = 23.703125
