Answer:
k = 16/3
Step-by-step explanation:
Start by calculating the difference on the left side.
1/4k - 4 + 5/4k = 3/8k + 2
Multiply both sides of the equation by 8
2k - 32 + 10k = 3k + 16
Calculate sum on left side
12k - 32 = 3k + 16
Subtract 3k and add 32 to both sides
9k = 48
Divide both sides by 9
k = 48/9 = 16/3

The length and the width of a rectangle are (2x+5) cm and (2x-7) cm respectively. Given that the area of the rectangle is 14cm^2, find its length and width.
Answers
Answer:
Length=13.07 and Breadth=1.07
Step-by-step explanation:
Area=l*b
14=(2x+5)(2x-7)
14=4x^2-4x-35
4x^2-4x-49=0
Using quadratic formula, we have x=(1±5sqrt(2))/2 but as length can't be negative, so x=(1+5*sqrt(2))/2
Length=13.07 and Breadth=1.07

Anyone know the answer?
Answers
Answer:
Step-by-step explanation:
(21 + 3y) + y = 90
21 + 4y = 90
4y = 69
y = 17.25
x = 21 + 3(17.25)
x = 21 + 51.75
x = 72.75
Answer check:
72.75 + 17.25 = 90
90 = 90 Corrrrrrect !
Explanation:
x = 3y + 21
And x + y = 90° (complementary angle)
Substitute x value in the equation:
3y + 21 + y = 90
4y + 21 = 90
4y = 69
y = 69/4
y = 17.25
x = 3(17.25) + 21
x = 51.75 + 21
x = 72.75

It will take 5 men 10 days to dig a hole half as big.
( Remember, the less people, the more time it will take. )
Answer:
10 men can dig 1 hole in 10 days
How long for 5 men to dig ½ hole?
The ratio to be concerned with is
(number of people / number of holes) = 10 days

it costs $20 for 4 play tickets and $35 for 7 play tickets. is costs per ticket constant? why or why not?
Answers
Answer:
Yes.
Step-by-step explanation:
Most people are going to say 4x2=8 so 20x2=40, then do a huge math mess up and think they discounting $1.33 after the first 4. this is incorrect.
Seeing as $20 is 4 tickets we can safely say, each ticket is $5 each.
Basic mathematics, 5x7=35. Paying for 7 tickets at $5 each, that is the correct constant price.

This is very urgent and I need to get it done soon, whoever is willing to help me I'll mark you as brainliest. Thank you!
Answers
Answer:
The united nations flag the translation can be any of the blue triangles and the reflection if the flag itself as it is symmetrical
Step-by-step explanation:
The united nations flag the translation can be any of blue triangles and the reflection if the flag itself as it is symmetrical.
How does reflection across axis work?When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If we study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
If you're reflecting a point (x,y) along x axis, then its abscissa will stay same but ordinates will negate. Thus (x,y) turns to (x, -y)
Similarly, if you're reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)
Therefore, The united nations flag the translation can be any of blue triangles and the reflection if the flag itself as it is symmetrical.
