So eight (8) less than (3) times a number ( 8 - 3x) is (=) twice the sum of x (2x) and (4) so the answer would be 8 - 3x = 2x + 4

What is the volume of a rectangular prism with the dimensions: base 3 1 2 cm, height 1 1 2 cm, and length 5 1 2 cm?

Elanso [62]

Answer:

The volume of a rectangular prism is $28\frac{7}{8}\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the rectangular prism is equal to

$V=BHL$

Convert the given dimensions to an improper fractions

$B=3\frac{1}{2}\ cm=\frac{3*2+1}{2}=\frac{7}{2}\ cm$

$H=1\frac{1}{2}\ cm=\frac{1*2+1}{2}=\frac{3}{2}\ cm$

$L=5\frac{1}{2}\ cm=\frac{5*2+1}{2}=\frac{11}{2}\ cm$

substitute in the formula

$V=(\frac{7}{2})(\frac{3}{2})(\frac{11}{2})=\frac{231}{8}\ cm^{3}$

Convert to mixed number

$\frac{231}{8}=\frac{224}{8}+\frac{7}{8}=28\frac{7}{8}\ cm^{3}$

How do you find a linear equation

Tasya [4]

Flip equation
$- 12x + 96 = y - 11$
add -96 to both sides
$- 12x + 96 + - 96 = \\ y - 11 + - 96 - 12x = y - 107$
divide both sides by -12
$\frac{ - 12x}{12} = \frac{y - 107}{12}$
ANSWER
$\frac{ - 1}{12} y + \frac{107}{12}$

The linear equation y=3x−5y=3x−5 y equals 3 x , minus 5 is in what form.

Roman55 [17]

I must make some assumptions here about what you may have meant by your "<span>linear equation y=3x−5y=3x−5 y equals 3 x , minus 5."

You've written "y=3x-5" three times on the same line of type. Why is that?

Let's change what you've typed to the following:

</span><span>linear equation y=3x−5

separate linear equation y equals 3x minus 5, or y=3x-5

Please go back and ensure that you have copied down this problem precisely as it was originally presented. Be careful not to duplicate info (as you did in typing "y=3x-5," followed by "</span><span>y equals 3 x , minus 5."
</span><span>
y = 3x - 5 is, as you say, "a linear equation." The slope of this line is 3 and the y-intercept is (0, -5).

As to form: This is a "slope-intercept equation of a straight line."

Other forms include "General form of the equation of a straight line," "Point-slope form."</span>
