Solve to find X. 3 ≥ -3x

Answers

Answer:

-1 ≤ x

Step-by-step explanation:

You just need to divide -3 on both sides.

-1 ≤ x

Note that since you are dividing by a negative number, the sign flips.

-1 ≤ x

Step-by-step explanation:

First start with the equation:

3 ≥ -3x

divide by -3 to get x positive and singular:

-1 ≥ x

and since we divided by a negative we need to flip the sign:

-1 ≤ x  would be your answer

Three randomly chosen California students were asked how many times they drove to Mexico last year. Their replies were 4, 5, 6. The geometric mean is:

Answers

Answer:

4.93

Step-by-step explanation:

Given 3 numbers a, b and c, the formula for calculating their geometric mean is expressed as:

GM = ∛a*b*c

Given the numbers 4, 5 and 6

geometric mean = ∛4 * 5 * 6

geometric mean = ∛20*6

geometric mean = ∛120

geometric mean = 4.93

Hence the geometric mean is 4.93

Expand and simplify: 3(m + 2) + 4( 6 + m)

Answers

Answer:

Step-by-step explanation:

Multiply through the 3 of the first bracket to get 3m +12. Then multiply out the second bracket by -2 to get -8m -2.

Write it out in a line: 3m + 12 - 8m -2

Simplify: -5m +10

Divide by -5 again to simplify further: m - 2

Answer:

=7m+30

Step-by-step explanation:

Distribute:

=(3)(m)+(3)(2)+(4)(6)+(4)(m)

=3m+6+24+4m

Combine Like Terms:

=3m+6+24+4m

=(3m+4m)+(6+24)
