Answer:

8/7 =x

Step-by-step explanation:

3 - 2(x - 4) = 5x + 3

Distribute

3 -2x +8 = 5x+3

Combine like terms

11 -2x = 5x+3

Add 2x to each side

11-2x+2x = 5x+2x+3

11 = 7x +3

Subtract 3 from each side

11-3 = 7x +3-3

8 = 7x

Divide each side by 7

8/7 =7x/7

8/7 =x

Find the midpoint of points A(8,-7) and B(3,-1) graphically

sukhopar [10]

Answer: (5.5, -4)

Step-by-step explanation:

You can use the midpoint formula to find the midpoint of point A and point B.

$M(\frac{x_{1}+x_{2} }{2}, \frac{y_{1} + y_{2} }{2})$

x₁ = 8

x₂ = 3

y₁ = -7

y₂ = -1

$M(\frac{x_{1}+x_{2} }{2}, \frac{y_{1} + y_{2} }{2})$

$M(\frac{8+3 }{2}, \frac{-7 +-1}{2} )$

$M(\frac{8+3 }{2}, \frac{-7 -1}{2} )$

$M(\frac{11 }{2}, \frac{-8}{2} )$

$M(5.5, -4 )$

Midpoint = (5.5, -4)

Hope this helps!

A cone has a volume of 5 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?

Pie

Answer:

15 $in^{3}$

Step-by-step explanation:

Given:

Volume of Cone= 5 $inch ^{3}$

Solution:

Formula:

Volume of Cone = $\frac{1}{3} \pi r^{2} h$

Volume of Cylinder= $\pi r^{2} h$

$\therefore$ We can say that

Volume of Cone = $\frac{1}{3} \times$ Volume of Cylinder

$\therefore$ Volume of cylinder = 3 $\times$ Volume of Cone

Now Substituting given data we get

Volume of Cylinder= 3 $\times$ 5

Volume of Cylinder= 15 $in^3$
