It these triangles are similar, then the sides of the triangles are in proportion:
<em>cross multiply</em>
<em>use distributive property</em>
<em>subtract 10y from both sides</em>
<em>divide both sides by 5</em>
<em>cross multiply</em>
<em>divide both sides by 8</em>
No values of X would answer this problem.
10x+1=10x+2
-10x -10x
3 = 0
Answer:
<u>Each cheeseburger cost $5.25</u>
Step-by-step explanation:
First, we must subtract the price of the taco, $2.75, from the total amount spent at dinner. This leaves us with 21 dollars.
Now, we must divide 21 by 4, this will show us the price of each cheese burger.
21 ÷ 4 = 5.25
So, each cheeseburger cost $5.25.
