0.4(2x+0.5)=3[0.2x+(-2)]-4<span>

</span>0.8x+0.2=0.6x-10

0.2x=-10.2

x= \frac{-10.2}{0.2}

x=-51

Find the volume and show work (round to the tenths)
Pani-rosa [81]

Answer:

120 km^3

Step-by-step explanation:

the base is a right triangle

A = (leg1 x leg2)/2 = (6 x 8)/2 = 24 km^2

the volume of a prism is base area x height

V = 24 x 5 = 120 km^3

Tell whether the linear equation is in slope-intercept form, point-slope form, or standard form.
Dmitry_Shevchenko [17]

Answer:

Standard form

Step-by-step explanation:

In this question, we have to figure out what form the equation is.

Our options are: point-slope form, slope-intercept form, and standard form.

Our forms are structed as followed below:

Point-slope form: y - y1 = m(x - x1)

Slope-intercept form: y= mx + b

Standard form: Ax + By = C

Now, we just need to find out which form the equation resembles.

You would notice that the linear equation "2x + 4y = 12" follows the structure of the standard form.

Side-by-side comparison:

2x + 4y = 12

Ax + By = C

Therefore, your answer would be standard form.
