<h2>4</h2>
Step-by-step explanation:

 
        
             
        
        
        
 52.5 Yards (yd). 
7 + 7 = 14
14 + 14 = 28 ( 10 + 10 + 4 + 4)
14 + 28 = 42 (4 - 2 + 8 = 10 + 20 + 10)
42 + 10.5 = 52.5
⚠⚠ if you need to multiply this by itself (squaring is the proper name) then the answer is 2756.25 Yards.

Answer:
Step-by-step explanation:
The total amount of punch that Jennifer made for her party is 5 Liters. Her brother made another 750 milliliters.
1000 milliliters = 1 liter
750 milliliters = 750/1000 = 0.75Liter
if they combine the two batches, the total amount made would be 
5 + 0.75 = 5.75Liter 
= 5.75 × 1000 = 5750 milliliters
The number of 180 milliliters servings would be 
5750/180 = 31 servings
There would be leftovers of 170 milliliters
 
        
             
        
        
        
Answer:
3/5   or
0.6
Step-by-step explanation:
You could change these fractions to decimals, but you may not be convinced that the answer you get is the same as just using fractions. I'll start by using fractions.
x - 2/5 = 1/5                        Add 2/5 to both sides
x - 2/5 + 2/5 = 1/5 + 2/5     The left side cancels to 0.
x = 1/5 + 2/5                       The denominators (bottom the fraction) are the same. Just add the tops.
x = (1 + 2)/5
x = 3/5
=======================
If you use your calculator to find 2/5 and 1/5, you can get the same answer as 3/5
2
÷
5
= 
0.4
By the same method, 1/5 = 0.2
Substitute into the original equation
x - 0.4 = 0.2                       Add 0.4 to both sides
x - 0.4 +0.4 = 0.2 + 0.4    The left side reduces just to x
x = 0.2 +0.4
x = 0.6
If you let your calculator do the work, like this
3
÷ 
5               
=
0.6
The answers are the same.
