The answers are x=4 and y=323/2

1) 40/2x-3=8

Multiply both sides by 2x-3 to get rid of fraction

40= 8(2x-3)

Distribute 8

40= 16x-24

Add 24 to both sides

64=16x

Divide by 16

4=x


2) 2y-3/40=8

Multiply both sides by 40 to red rod of fraction

2y-3=320

Add 3 to both sides

2y= 323

Divide by 2

Y=323/2

Now just describe the differences in solving them


FYI / means fraction, right after the slash is bottom of fraction

Consider the volume of the region shown below, which shows a right circular cone with top radius 3 cm and height 10 cm. We have
koban [17]
I have the same problem here with a slight change in the given values:

radius is 2 & height of 6 indicates the bounding line is y = 3 x---> x = y / 3.... 

<span>thus the [ π radius ² thickness ] yields π (y² / 9 ) <span>dy ,</span> y in [ 0 , 6 ] for the volume... </span>

a Riemann sum is then : y_i = 0 + i [ 6 / n ] = 6 i / n , i = 1,2,3...n and do a right side sum 

<span>π Σ { i = 1,2,3..n } [ 36 i² / 9 n² ] [ 6 / n ]
</span>
I hope my guide has come to your help. God bless and have a nice day ahead!

△ABC is similar to △XYZ. Also, side AB measures 6 cm, side BC measures 18 cm, and side XY measures 12 cm.
Serggg [28]

Answer:

value of sides YZ is 36 cm

Step-by-step explanation:

Similar triangles states that the length of the corresponding sides are in proportion.

Given that: ΔABC is similar to ΔXYZ

then;

Corresponding sides are in proportion i.e

\frac{AB}{XY}=\frac{BC}{YZ}=\frac{AC}{XZ}    .....[1]

As per the statement:

side AB = 6 cm, side BC =18 cm and side XY = 12 cm.

Substitute these in [1] to solve for side YZ;

\frac{6}{12}= \frac{18}{YZ}

or

\frac{1}{2} = \frac{18}{YZ}

By cross multiply we have;

YZ = 36 cm

Therefore, the value of sides YZ is 36 cm
