Answer:
Is that it's not about the answers and the questions
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.
Answer:
20r+15n
Step-by-step explanation:
just flip the equation
The right answer is k :).
Hope you have a nice day
Let's use the variable, x, to represent the unknown number.
We can represent the words, "the sum of a number and six, as : x + 6
The words, " 2 less than the sum", can be represented as: x + 6 - 2
The words, "the product of the number and three", can be written as: 3x
Now create an equation using "is equal to" to join the expressions:
x + 6 -2 = 3x
Now combine like terms and use inverse operations to solve for x:
x + 6 -2 = 3x
x + 4 = 3x
x + 4 - x = 3x - x
4 = 2x
4/2 = 2x/2
2 = x
The unknown number is 2
