Answer:
3(3+7)
Step-by-step explanation: you factor out the greatest common multiple. 3 times 3 is 9 and 3 times 7 is 21
Since 25 feet = 1/2 an inch, we know that an inch = 50 feet. 600/50 = 12 and 1000/50 = 20 so the whole park is 12x20 inches on the scale drawing.
So the first thing we need to do is set up an equation (using x to represent the number). Then, we'll solve it to get the answer.
Step 1: Translate the word problem into an equation
Word problem: The sum of nine and six-tenths and a number is thirteen and two-tenths.
Equation:
+ x = ![13 \frac{2}{10}](https://tex.z-dn.net/?f=13%20%5Cfrac%7B2%7D%7B10%7D)
Step 2: Isolate x by subtracting
from each side
+ x -
=
- ![9 \frac{6}{10}](https://tex.z-dn.net/?f=9%20%5Cfrac%7B6%7D%7B10%7D)
Step 3: The numbers on the left cancel out, leaving x alone
x = ![3 \frac{6}{10}](https://tex.z-dn.net/?f=3%20%5Cfrac%7B6%7D%7B10%7D)
Step 4: Convert the answer to decimals
x = 3.6
