Answer:
x ≤ 2
Step-by-step explanation:
Isolate the variable, x. Note the ≤ sign, treat it like an equal sign, what you do to one side, you do to the other.
First, subtract 3 and x from both sides:
2x (-x) + 3 (-3) ≤ x (-x) + 5 (-3)
2x - x ≤ 5 - 3
Simplify:
2x - x ≤ 5 - 3
x ≤ 2
x ≤ 2 is your answer.

Answer: First option.
Step-by-step explanation:
Given the following equation provided in the exercise:
![\sqrt[3]{x+8}=-4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%2B8%7D%3D-4)
You can follow the steps indicated below in order to find the solution of this equation:
1. Cubing both sides of the equation, you get:
![(\sqrt[3]{x+8})^3=(-4)^3\\\\x+8=-64](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7Bx%2B8%7D%29%5E3%3D%28-4%29%5E3%5C%5C%5C%5Cx%2B8%3D-64)
2. Finally you must subtract 8 from both sides of the equation:
You can notice that this solution matches with the first option.
Lets find that out writing equations and solving them, a multiple of 1/6 is something like this (1/6)x, so we have
(1/6)x > 3/6
and
<span>(1/6)y < 4/6
</span>lets solve both equations:
<span>(1/6)x > 3/6
</span>x > 6(3/6)
x > 3
<span>(1/6)y < 4/6
</span>y < 6(4/6)
y < 4
So the number must be between 3 and 4, which is obvious, lets try with 3.5 then, that is 3 5/10 or 35/10 = 7/2 in fractional form, and lets try it out:
(1/6)(7/2) = 7/12
finally we compare with the original fractions:
1/6 < 7/12
2/12 < 7/12
So, it comply with being greater than 1/6, now lets compare with 4/6
7/12 < 4/6
<span>7/12 < 8/12
</span>therefore is also smaller than 4/6 and hence 7/12 is a multiple of 1/6 between 3/6 and 4/6
Solving:
<span>.89 * 1,475,623 = 1,313,304.47
</span>
So, the answer would be:
approximately equal to <u>1,313,305</u> number of scores were below 670
<span><span>l=w+4
A=w*l
A=w*(w+4)
8=w*(w+4)
8=w^2+4w
w^2+4w-8=0
w=1.464=1.5
l=1.5+4=5.5</span><span>
</span></span>
