Answer:
6.08
Step-by-step explanation:
For four brushes its 16 and for two rollers and trays its 16. Add that with the tax and you’ll get 33.92. Subtract 40 with the overall cost to get 6.08
We know that the area of a rectangle is equal to the width multiplied by the length. So in this case the algebraic expression is (x+5)*(3x+10). You get 3x^2 +10x +15x +50= 3x^2 +25x +50.
Answer: Choice B
x+6y = 29 and x+3y = 24.5
==============================================
Explanation:
x is the cost of a throw blanket
On top of this cost is the cost to embroider letters on it
Your name has 6 letters so it costs you an extra 6y dollars. Overall, you pay x+6y dollars. It says that your cost is $29
So that's where x+6y = 29 comes from.
-------------
Similarly, your friend also pays x dollars for the blanket itself plus an extra 3y dollars for the 3 letters in their name. Overall, they pay x+3y dollars. We're told they spent $24.50 which is where the equation x+3y = 24.5 comes from.

Answer:
(5/2,-5)
Step-by-step explanation:
plug in zero for each of the variables to get the other one

2(0)-y=5
-y=5
y=-5
