Answer: x = 6

Step-by-step explanation: To solve for x in this equation, we want to get x by itself on the left side of the equation.

Since x is being multiplied by 3, to get x by itself, we need to divide by 3 on the left side of the equation. Since we divide by 3 on the left side, we must also divide by 3 on the right side. On the left side, notice that the 3's cancel out so we are simply left with x. On the right side, we have 18 divided by 3 which is 6 so we have x = 6.

Finally, remember to check your answer by substituting a 6 back into the original equation. So we have 3(6) = 18 which is a true statement so our answer, x = 6, is correct. Image if provided below.

Which expressions are equivalent to 12 - 14/3m + 2/3m ?

yawa3891 [41]

ANSWER

The correct answers are option B and D.

$12 - 4m$

EXPLANATION

The given expression is

$12 - \frac{14}{3} m + \frac{2}{3}m$

We need to simplify the above expression in order to determine the option that is equivalent to it.

The least common denominator for the last two fractions is 3.

This implies that,

$= 12 + \frac{ - 14m + 2m}{3}$
We simplify to obtain,

$= 12 + \frac{ - 12m}{3}$

This further simplifies to give us,

$12 - 4m$

This is option B.

When we further factor -4, we get,

$-4(m-3)$

This is option D.

Answer:

$A=384\ cm^2$

Step-by-step explanation:

Let the sides of a triangle be 6x,8x and 10x.

Perimeter of the triangle, P = 96 cm

We need to find the area of the triangle.

P = sum of all sides

6x+8x+10x = 96

24x = 96

x = 4

Sides are :

6x = 6(4) = 24 cm

8x = 8(4) = 32 cm

10x = 10(4) = 40 cm

Area,

$A=\dfrac{1}{2}\times b\times h\\\\A=\dfrac{1}{2}\times 24\times 32\\A=384\ cm^2$

So, the area of the triangle be $384\ cm^2$ .
