The third equation: V = (7 x 6) / 2) x 8.
(7 x 6) / 2 would be the area of the triangle.
The volume of any prism is (area of base) x height.
So (7 x 6) / 2 (the area of the base), multiplied by 8 (the height), would give you the volume of this shape.

The value of which makes 2/3(1/4x-2)=1/5(4/3x-1)

sertanlavr [38]

Answer:

-34/3

Step-by-step explanation:

2/3(1/4x-2)=1/5(4/3x-1)

2/12x-4/3=4/15x-1/5

1/6x-4/3=4/15x-1/5

1/6x-4/15x=-1/5+4/3

-1/10x=-3/15+20/15

-1/10x=17/15

x=(17/15)/(-1/10)

x=(17/15)(-10/1)

x=-170/15

x=-34/3

Li graphed the equation y=2x+3. Which table of values did Li use to create her graph?

Natali5045456 [20]

Answer:

See attached picture.

Step-by-step explanation:

To graph the line, start at (0,-3) since b=

-3 in the equation. This is the y-intercept.

Mark this point. From this point, move

down 2 units and to the right 1 unit. Mark

this new point at (1,-1). Connect the points

with a line. See attached picture.

When 2(3/5x+2 3/4y-1/4x-1 1/2y+3) is simplified, what is the resulting expression?

erik [133]

Answer:

Option B is correct.

Step-by-step explanation:

$2(\frac{3}{5}x+ 2\frac{3}{4}y-\frac{1}{4}x-1\frac{1}{2}y+3)$

We need to solve the above expression.

First Convert Mix fraction into improper fraction

$2(\frac{3}{5}x+ 2\frac{3}{4}y-\frac{1}{4}x-1\frac{1}{2}y+3)\\=2(\frac{3}{5}x+ \frac{11}{4}y-\frac{1}{4}x-\frac{3}{2}y+3)$

Combining the like terms

$=2(\frac{3}{5}x-\frac{1}{4}x+ \frac{11}{4}y-\frac{3}{2}y+3)$

Solving like terms

$=2(\frac{3x*4-5x}{20}+ \frac{11y-3y*2}{4}+3)\\=2(\frac{12x-5x}{20}+ \frac{11y-6y}{4}+3)\\=2(\frac{7x}{20}+ \frac{5y}{4}+3)$

Multiply each term with 2

$=2*\frac{7x}{20}+ 2*\frac{5y}{4}+2*3\\=\frac{7x}{10}+ \frac{5y}{2}+6$

$=\frac{7x}{10}+ 2\frac{1}{2}y+6$

So, Option B is correct.
