Answer:
a triangle because a friangel always adds up to 180° so. 180 -160 = 20 and both of the other 2angles can be 10°
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.
Your equation is just to multiply 480 by 3/4.
Easy way to do these quick.
480 (3/4) is the same as (480 * 3) / 4
480 / 4 = 120
By simplifying, you are left with just 120 * 3 in the numerator
120 * 3 = 360
There are 360 people on the plane.
If you need to check your answer:
360 / 480
Take away the zeros at the end by dividing both by 10
36 / 48
Divide both by 6
6 / 8
Now divide by 2
3 / 4
