Answer:
Step-by-step explanation:
This is actually a very important question and it is very subtle. Let's just take an ordinary segment.
Suppose we have a segment that is this long
=========o=========
The segment up to the o is nine equal signs long.
The segment after the o is also nine equal signs long.
Here's the crunch. Since they are equal, the ratio is 1 to 1. The segment is divided in half.
Now take the second half of the question.
======o============
The left side of the o is 6 equal signs long.
The right side of the o is 12 equal signs long.
The ratio is 1:2. There are still 18 equal signs but now they are divided as 6/12 which is not the same thing as 9/9
Very interesting question.
3x+15+11x-5/2=47
14x+10/2=47
7x+5=47
7x=42
x=6
Answer:
of oil are needed for each cup of vinegar.
Step-by-step explanation:
Given:
A recipe of salad dressing calls for ¼ cup vinegar to ⅔ cup oil.
Now, to find the cups of oil are needed for each cup of vinegar.
So, we solve by using unitary method:
If 
cup of vinegar is needed for oil of 
cup.
So, 1 cup of vinegar is needed for oil of = 
= 
(the fractions turns reciprocals as the division changes into multiplication)
= 
= 
cups.
Therefore, of oil are needed for each cup of vinegar.
Answer:
I don't see any answer choices, but read my explanation
Step-by-step explanation:
Any line with a slope of 3 would be parallel to y=3x+2.
For example,
y=3x+4
y=3x-1
y=3x
All of these lines are parallel to the original equation
Answer:
Step-by-step explanation:
Given
Rate = 130.16 miles for 5 gallons
Required
Number of gallons used for a journey of 60 miles
The rate in miles per gallon is calculated as:
When distance = 130.16 and gallons = 5, we have:
When distance = 60 miles.
Substitute 60 for distance and 26.032 for rate in
Cross Multiply
