It is a linear equation with only one unknown, although it looks strange because of the fractions, so lets get rid of the fractions:
<span>2/x = 1/4
</span>(2/x) = (<span>1/4)
</span>4*(2/x) = <span>1
8/x = 1
8 = 1*x
x = 8
that is the solution</span>
Answer:
see explanation
Step-by-step explanation:
4a + 8 4
2a² + 8a 2a
12a² - 8a 4a
4 - 6a 2

Answer: Choice A) 1/7, 3/7, 4/7, 6/7</h3>
========================================================
Explanation:
All of the fractions, for each of the answer choices, has a denominator of 7. This means we can ignore them when it comes to sorting out the fractions. Focus only on the numerators.
- Choice A has numerators 1,3,4,6 in that order from left to right. This is in increasing order (ie smallest to largest), so this is why choice A is the answer.
- Choice B has the numerators 6,4,3,1 in that order. This is from largest to smallest, which is the complete opposite of what we want. Choice B is incorrect.
- Choice C has numerators 1,6,4,3 which is in neither order. Rule this out as well.
- Choice D has numerators 3,4,1,6 and we can rule it out for similar reasoning as choice C.
If you want, you can convert each fraction to decimal form to sort out the decimals that way, then convert back to fraction form.
First part: 1 is less than the sum of x and 3: 1 < x+3.
Second part: the sum of x and 3 is less than 9.
Obviously 1 < 9.
Taking another look at 1<x+3, we can solve for x: -2<x. Draw a dashed vertical line thru x = -2.
Taking another look at x+3<9, subtract 3 from both sides. Then x<6.
Draw a dashed vertical line thru x=6.
Shade the area between these two vertical lines to obtain the desired graph.
Answer:
The answer is c. Sorry my last answer was wrong i think. If its abc its probably the other way around i didnt see which way it was going. Though if i was right the first time its either a or c
