Answer:
25
Step-by-step explanation:
165-140=25
140-115=25
115-90=25
90-65=25
65-40=25
This has infinitely many solutions if that is all that the question asked...
2x+3y=12
3y=-2x+12
y=(-2x+12)/3
So for any value of x you choose it will give you the corresponding y value that makes your original equation true.
Answer:
14 miles if that's how far he went up
17miles if you're calculating his distance covered
Answer:
A graph shows zeros to be ±3. Factoring those out leaves the quadratic
(x-2)² +1
which has complex roots 2±i.
The function has roots -3, 3, 2-i, 2+i.

Answer:
160 tiles.
Step-by-step explanation:
First let's make an equation.
Each tile costs $4, let's make <em>t=number of tiles.</em>
+$15.82, and the total cost being $655.82
So ideally our equation would look like
<em>4t+15.82=655.82</em>
<em />
Now solve.
First, subtract <em>15.82 </em>on both sides.
<em>4t=640</em>
Second, divide <em>4 </em>on both sides to make the variable <em>t </em>by itself.
<em>t=160</em>
<em />
So, the contractor purchased 160 tiles.
