NISA [10]
The least (or lowest) common denominator of 3, 16 and 8 is 16. That already points us to answer A.

Checking for each fraction:

1/2 * 8/8 = 8/16
3/16 * 1/1 = 3/16
7/8 * 2/2 = 14/16

Yep. Answer A.

How many ways can a group of three boys and three girls be seated in a row of six seats if boys and girls must alternate in the​
IgorC [24]

Answer:

24

Step-by-step explanation:

there are 6 seats and 3 boys, 3 girls.

First seat can be given to either boy or a girl.

So there are two ways.

If a boy is selected say, then he has to occupy 3rd and 5th only.

There are 2 ways

Now available positions are 2nd, 4th and 6th, in this girls can be arranged in 3! ways = 6

So total number of ways =

2x2x6 = 24

I dont know how to do graphing pls help
yarga [219]

Answer:

Solution: (-1, -1)

Step-by-step explanation:

y=4x+2

y=-4/3x-2

Solve by graphing.

First, you need to plot the y-intercept.

y=4x+<u>2</u>

2 will be your y-intercept.

Next, you plot your slope.

y=<u>4x</u>+2

From your y-intercept, you will go up 4 and right one space, if you run out of space go down 4 and left 1.

Now repeat the same steps for the next one.

y=-4/3x<u>-2</u>

Plot your y-intercept.

y=<u>-4/3x</u>-2

because your slope is negative you will go down 4 and right 3, if you run out of room go up 4 and left 3.

Then draw connecting lines and wherever the lines intersect, that's going to be your solution. In this case, the solution is (-1, -1).

Hope this helps :)

PLZ HELP ME ITS DUE RIGHT NOW woth 18 points
Anika [276]

Answer:

The answers to the first question are A,C,D

The answer to the second question is YZ=16

Step-by-step explanation:

(1st Question)

Since <K and <M Are equal, and both <L's are equal, KL and ML are congruent (Answer choice) because of the ASA postulate.

You need to create the following equation to find the length of KN and MN 7x-4=5x+12

(Get the "x" variable to one side)

2x-4=12

(Isolate the variable)(Remove the 4)

2x=16

(Divide the 2 by itself to remove it from the x, remember to divide both sides by 2)

x=8 (Answer Choice)

Plug in the x value into each equation

KN= 7(8)-4

KN= 56-4

KN= 52

MN= 5(8)+12

MN= 40+12

MN= 52 (Answer Choice)

MN=KN

(Second Question)

Since XWY(20) is half of XWZ(40), ZWY also equals 20.

This now proves the triangle is congruent by the AAS postulate.

Since the triangles are congruent, if XY = 16, YZ also equals 16.
