What is the value of x in the equation 3x-4y=65 when y=4?

Simple...plug n chug..

3x-4(4)=65

3x-16=65

Now, isolate the variable, x....

3x-16=65
    +16 +16

3x=81

Now, divide,

\frac{3x}{3} = \frac{81}{3}

x=27.

Answer:

<em>XY = 92 units</em>

Step-by-step explanation:

<u>Similar Shapes</u>

Two shapes are similar if all their corresponding side measures are in the same proportion.

The triangles UVW and YVX are similar because their side lengths are in the proportion 1:2, given the tick marks provided in the drawing.

This means that the measure of VX is twice the measure of VW,

The measure of YV is twice the measure of UV

The measure of XY is twice the measure of UW

This last proportion gives the equation:

z + 46 = 2z

Solving for z:

z = 46

Thus, XY = z+46 = 92

XY = 92 units

Winton was givin $14 to spend at a school fair he spent 3/7 playing games how much money is lift
Ksivusya [100]
<h3><u>Question:</u></h3>

Winton was given $14 to spend at a school fair he spent 3/7 playing games how much money is left

<h3><u>Answer:</u></h3>

Amount left with winton is $ 8

<h3><u>Solution:</u></h3>

Given that Winton was given $14 to spend at a school fair

He spent \frac{3}{7} playing games

To find: money left with Winton

From given information,

Money given to Winton = $ 14

Amount spent on games = \frac{3}{7}

Thus we can say,

Amount spend on games = \frac{3}{7} of total money he has

\rightarrow \frac{3}{7} \times 14 = 3 \times 2 = 6

Thus he spend $ 6 on playing games

<em><u>Money left with Winton:</u></em>

Money left = total money he had - money spent on playing games

Money left = 14 - 6 = 8

Thus amount left with winton is $ 8
