The correct answer is:
[C]: "
" .
____________________________________________________Explanation:____________________________________________________Given:
____________________________________________________ 2 / (9x) = 4 / 7 ; solve for "x" ;
____________________________________________________Cross-multiply:
→ (9x)*4 = 2 * 7 ;
→ 36x = 14 ;
Divide each side of the equation by "36" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
→ 36x / 36 = 14 / 36 ;
x = 14/ 36 ;
→ x = 14/36 = (14÷2) / (36÷2) = 7/18 ;

The answer is: "
" ;
→ which is:
Answer choice: [C]: "

Thank you for posting your question here at brianly. I hope the answer will help you. Below is the solution:
or segment from (4,0) to (-4,0), y is always zero because straight segment.
<span>in that case x*y=x*0=0 </span>
<span>and x+y=x+0=x </span>
<span>if you choose x=4-t where t goes from 0 to 8 you should get </span>
<span>r(t)=0i+(4-t)j </span>
Answer:
Step-by-step explanation:
Here are the steps to follow when solving absolute value inequalities:
Isolate the absolute value expression on the left side of the inequality.
If the number on the other side of the inequality sign is negative, your equation either has no solution or all real numbers as solutions.
If your problem has a greater than sign (your problem now says that an absolute value is greater than a number), then set up an "or" compound inequality that looks like this:
(quantity inside absolute value) < -(number on other side)
OR
(quantity inside absolute value) > (number on other side)
The same setup is used for a ³ sign.
If your absolute value is less than a number, then set up a three-part compound inequality that looks like this:
-(number on other side) < (quantity inside absolute value) < (number on other side)
The same setup is used for a £ sign
Question:
Suppose that the populations of the United States and China both increase by 12 million people in one year. What would be the relative change for each country? Answer to the nearest tenth of a percent (1 decimal place). Make sure that you fill in each answer area before checking "How Did I Do?".
If you assume that the U.S. population is about 300 million, an increase of 12 million would result in a relative change of Number %.
If you assume that China has about 1 billion people, an increase of 12 million would result in a relative change of Number %.
Answer:
The relative change of the United States and China is 4% and 1.2%, respectively.
Step-by-step explanation:
Given
Represent population with p. So, we have:
United States
China
Required
Determine the relative change for each country
Relative change, C is calculated as:
For United States
For China
The relative change of the United States and China is 4% and 1.2%, respectively.
180/10=18 is one but the easitest way is with tens or hundreds
