Answer:

<h2>steps A & B</h2><h2 />

Step-by-step explanation:

5x + 9 = 2x - 3

subtract 2x from both sides

5x - 2x + 9 = 2x - 2x - 3

simplify:

3x + 9 = -3

subtract 9 from both sides:

3x + 9 - 9 = -3 - 12

simplify:

3x = -12

divide 3 on both sides:

3 3

simplify:

x = -4

6) 2(n + 5) = -2<br> help i wasn’t paying attention in my google meet

bonufazy [111]

Answer: the answer is -6

2(n+5) = -2

2n + 10 = -2

2n = -2 - 10

2n = -12

2n *1/2 = -12 * 1/2 = -6

n = -6

a rectangular prism measures 3 in by 8 in by 9 in. what is the side length of a cube with the same volume?

Novay_Z [31]

Answer:

6 in.

Step-by-step explanation:

Rectangular prism

V = lwh l = 8 W = 3 h = 9

= 8(3)(9)

= 216

Cube

$V = s^{3}$ where s = length of side

216 = $s^{3}$

$s = \sqrt[3]{216}$ = 6

What is the value of x?<br><br> Enter your answer, as a decimal, in the box.

Katarina [22]

Answer:

$x=50.6cm$

Step-by-step explanation:

Triangle MAB is similar to triangle MNP

Since the triangles are similar, the corresponding ratios are in the same proportion.

Therefore we can write the relation;

$\frac{|MB|}{|MP|}=\frac{|MA|}{|MN|}$

$\frac{x}{72.6}=\frac{46.2-14}{46.2}$

This implies that;

$\frac{x}{72.6}=\frac{32.2}{46.2}$

We multiply both sides by 72.6 to get

$\frac{x}{72.6}\times 72.6=\frac{32.2}{46.2}\times72.6$

$\Rightarrow x=50.6$

Hence the value of $x$ is 50.6 cm
