Answer:

Option (a) is correct.

x=\frac{1}{4k}

Step-by-step explanation:

Given: Equation 11kx + 13kx = 6

We have to solve for x and choose the correct option from the given options.

Consider the given equation  11kx + 13kx = 6

Taking kx common, we have,

kx (11+13) = 6

Simplify, we have,

24kx = 6

Divide both side by 24, we have,

kx=\frac{6}{24}

Simplify, we have,

kx=\frac{1}{4}

Divide both side by k, we have,

x=\frac{1}{4k}

Thus, Option (a) is correct.

24kx = 6
kx = 6/24
kx = 1/4
x = 1/4/k
x = 1/4k

Answer: A) X = 1/4k or the first option.

A bag contains yellow marbles and red marbles,65 in total. The number of yellow marbles is 5 more than 4 times the number of red
Lostsunrise [7]
Let x equal the number of red marbles.
65 = x + (4x + 5)
65 = 5x + 5
60 = 5x
12 = x
65 - 12 = 53
53 yellow marbles.

Anyone know how to find the missing length ?
Svet_ta [14]

Answer:

so i'm assuming you'd use Pythagoras:

so 15^2-12^2=81

square root it=9 which is I

to find T we do 41^2-9^2=1600

square root that is 40 so T=40

a piece of rope 33ft long, cut into two pieces so that one piece is half the length of the other, how long is each piece of rope
s344n2d4d5 [400]
Shorter piece = x
Longer piece = 2x

x + 2x = 33

3x = 33

x = 11 feet

2x = 11 × 2

2x = 22 feet

So one piece will be 11 feet and the other will be 22 feet.

Hope this helps!

What is 4x-2y=8 and y=2x+1 using substitution
Setler [38]

Answer:

No Solution

Step-by-step explanation:

4x-2y=8

y=2x+1

Make the first equation into where it says y=.

-2y=-4x+8

y=2x-4

Substitute either equation into the other as y=.

2x+1=2x-4   or    2x-4=2x+1

Switch terms around so they're with their like terms. Make sure it becomes the opposite when switching.

2x-2x=-1-4    or    2x-2x=4+1

0=-5                     0=5

Since x did not come back to equal an answer, this problem is not workable. There is no solution to it. If you were to do it a different way, there still would not be a solution to it.
