Proportions are very simple once you get the hang of them! What you do is cross multiple. :)
1. x/8=5/16
You first start by multiplying x and 16
Then multiply 5 and 8
So now you have 16x=40
Finally divide 16 from each side
You get: x+0.4!
2. 5/12=15/x
Remember to cross-multiply!
Now we have 5x=180
Next divide 5 from each side
You get: x=36!
Answer: 3
Step-by-step explanation: To solve for A we need to get it by itself by doing the inverse of mulitplication, which is, division. 27/9=3, so a=3.
12L=720
L=720/12
L=60 ANS. FOR THE LENGTH.
W=60/5=12 ANS. FOR THE WIDTH.
Evidence:
144=2*60+2*12
144=120+24
144=144
<h2>20°</h2>
In this problem, we need to use some <u>division</u>.
To find the value of x, divide 4 from 80, and we get:
80 ÷ 4 = 20
The final answer is:
<h3>20°</h3>
To verify the answer, we need to multiply:
20 × 4 = 80
