<u>1. </u>Subtract 24 from both sides
-3x = -27 - 24
Simplify -27 - 24 to -51
-3x = -51
Divide both sides by -3
x = -51/-3
Two negatives make a positive
x = 51/3
Simplify 51/3 to 17
<u>x = 17</u>
<u>2.</u> Regroup terms
n/5 - 17 = 33
Add 17 to both sides
n/5 = 33 + 17
Simplify 33 + 17 to 50
n/5 = 50
Multiply both sides by 5
n = 50 * 5
Simplify 50 * 5 to 250
<u>n = 250</u>
The slope of the line is 1/4
Let w be the number of weeks. He withdraws $25 per week, so in w weeks, he withdraws 25w. He starts with $500, so after w weeks he has 500 - 25w. He wants this amount to be at least $200. "At least" means "greater than or equal to."
500 - 25w >= 200
-25w >= -300
w <= 12
Answer: Keith can withdraw $25 per week for at most 12 weeks.
You plug in 2x + 4 into the y for the other equation (3x +y ) and solve for it
+7 would be the answer i believe
