Answer:
100(a divided by b)
this is because for example, 1/2
100(1 divided by 2)
100(0.5)
50
50%
Answer : 46°
These two angles have the same measure because they are alternate interior angles.
1.31 + 1.23 = 2.54
2.54 + 1.23 = 3.77
So, keeping that up,
3.77 + 1.23 = 5
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.
When you are looking for this, the best way to do this is to divide 28 by 7. This will give you 4.
The other way to do this is to list the factors of 28, which are 1,2,4,7,14,28, and you will then be able to see which two are paired.
In this case, x is 4.
