Step-by-step explanation:

3x - 2x + 8 = 12; x=4

Now, Evaluate the value of x

3(4) - 2(4) + 8 = 12

12 - 8 + 8 = 12

12 + 0 = 12

12 = 12

Find the volume length 10 2/5 cm, width 3 cm, height 8 1/3 cm

AURORKA [14]

Answer:

260 cm

Step-by-step explanation:

formula for finding volume:

l x w x h = v

l=length w=width h=height v=volume

$10\frac{2}{5}$ × 3 × $8\frac{1}{3}$

$10\frac{2}{5}$ = $\frac{52}{5}$

how did i do that?

cross multiply the whole number and the denominator together and add the product by the numerator.

$8\frac{1}{3}$ = $\frac{25}{3}$

so, $\frac{52}{5}$ × $\frac{25}{3}$ × $\frac{3}{1}$

cross simplify(dont have to do it just makes everything easier)

and you get:

$\frac{52}{1}$ × $\frac{5}{1}$ × $\frac{1}{1}$

and you get $\frac{260}{1}$

$\frac{260}{1}$ = 260 cm

Answer:

To get the area of a parallelogram

Step-by-step explanation:

A=bh is the formula for an area so option D is definitely wrong.

The formula for the area of a triangle is $\frac{1}{2} *b*h$ .

The formula for the area of a circle is πr²

The formula for the area of a parallelogram is A=bh

A=bh is the formula for the area of a parallelogram.

Use the scenario to answer the question.

Dmitry [639]

Given the steps used to calculate the interquartile range, Bryan did not make any mistake.

<h3>What is the interquartile range?</h3>

The interquartile range is the difference between the third quartile and the first quartile.

Third quartile = 3/4(n + 1) : 3/4 x 10 = 7.5 term : (14 + 16) / 2 = 15
First quartile = 1/4 x (n + 1) 1/4 x 10 = 2.5th term : (6 + 6) / 2 = 6
Interquartile range = 15 - 6 = 9

Find the equation of the line.

mario62 [17]

Answer:

y = 2/3x - 7

Explanation:

First we must turn 3x + 2y = 6 to slope intercept form. In order to do this first subtract 3x on both sides of the equal sign, so we can get 2y by its self. Now we're left with 2y = -3x + 6 .

Next divide 2 from both sides to get y by its self. Now you got y = -3/2x + 3 (since 6 can be divided by 2 it's a 3 now) Look above to see y= -3/2x +3 graphed. ⤴⤴⤴

To find out the other equation we first need to know what its y-intercept is, and luckily for us we've already been given -3.

Look above to see (6,-3) graphed. ⤴⤴⤴

Look above to see both y = -3/2x + 3 and

y = 2/3x -7 graphed. ⤴⤴⤴

This is a bit lengthy, but I hope you get it :)
