The scale is 1 inch = 5 miles.
Multiply total inches by 5 miles:
4 x 5 = 20
Answer: 20 miles
Answer:
The diameter would be 11 feet
Step-by-step explanation:
C = pi * d
we don't know D so we rearrange the equation to solve for D by dividing both sides by pi:
C/pi = d
Now we plug in everything
11pi/pi = d
The pi cancel each other out leaving with 11 feet
Therefore D = 11 feet
Answer:
3x + 21 or 21 + 3x
Step-by-step explanation:
Remark
This is an example of the distributive property. Of all the fundamental rules used in solving equations, this is likely the most important, at least at beginning levels.
Solution
What this is saying is two things.
1. you must multiply both terms on either side of the + sign by the factor outside the brackets.
2. You must not destroy a plus (or minus) sign unless the two terms inside the brackets are exactly the same.
3(7 + x) The terms are not the same, so your answer must have a plus sign
Left side of the plus: 3*7
Right side of the plus: 3 * x
The answer then is 21 + 3x
It is more commonly written as 3x + 21
