-1≤ 3x-10≤ 2
Add 10 to each side
-1+10≤ 3x-10+10≤ 2+10
9≤ 3x≤ 12
Divide each side by 3
9/3≤ 3x/3≤ 12/3
3≤ x≤ 4
Answer:
3 ≤ x ≤ 4
Step-by-step explanation:
Step 1: Add 10 to all parts/sections.
Step 2: Divide all parts/sections by 3.

Answer:
588,000,000.
Step-by-step explanation:
Inserting commas every 3 digits from the right, we have:
587,881,188 so that is 587 million and 881,000.
As 8 is the next digit after the 587 we add 1 to 587 to make 588 million.

The answer is never.
Step-by-step explanation:
A scalene triangle is the one, which has all the three sides unequal. A scalene triangle has no equal sides so it has no lines of symmetry as a line of symmetry would divide the triangle evenly.
Therefore, the answer is never.
A scalene triangle NEVER has symmetry with respect to a line containing an altitude of the triangle.
Answer: Never/False
Explanation: A scalene triangle "never" has a symmetry with respect to a line containing an altitude of the triangle.

Answer: A ) 463.01 m³
Answer: since you did not provide the sphere in order to find the volume there is no way to find the volume. In order to find the volume if a sphere we simply have to use the following formula : v = ¾(Pi)r³.

of the fraction by anything you want to. You just have to do exactly the same to both of
them.
The way to simplify a fraction is to divide both the numerator and denominator by their
greatest common factor.
Do you see all of those 'x's on the top and bottom ? The top and bottom can
both be divided by x-cubed.
Numerator:
Divide (-4³) by x³, and you have (-4) left.
Denominator:
Divide (x³ - 2x⁴) by x³, and you have (1 - 2x) left.
So, the simplified fraction is [ -4 / (1 - 2x) ].
That's a perfectly good answer, but you could make it look a little prettier
if you multiply the top and bottom both by -1 . Then it would be
4 / (2x - 1) .
Either one is fine.
