Step-by-step explanation:
Assuming that de + ef = df, we can create the expression:
(4x + 10) + (2x - 1) = 9x - 15
Combine like terms to get:
6x + 9 = 9x - 15
The rest is basic algebra after this point.
6x + 9 = 9x - 15
-6x +15 -6x +15
______________
24 = 3x ----> x = 8
Next, plug the x value into the df equation to find df.
df = 9(8) - 15
df = 72 - 15
df = 57

if it takes 10 men 10 days to dig a hole how long will it take 5 men to dig a hole that's half as big
Answer:
10 days
Step-by-step explanation:
It will take 10 men 5 days to dig a hole half as big.
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
5 people digging ½ hole will take 10 days.

it costs $20 for 4 play tickets and $35 for 7 play tickets. is costs per ticket constant? why or why not?
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.

When p= 12, t= 2, and s= 5, r= 18. If rvaries directly with p and inversely with the product of sand t, what is the
constant of variation?
Answer:
15
Brainliest, please!
Step-by-step explanation:
r = kp/(st)
p = 12, t = 2, s = 5, r = 18
18 = k(12)/(2)(5)
18 = 12k/10
12k = 180
k = 15

Seven less than four times a number is nine. FIND the number
Answer:
4
Step-by-step explanation:
4 times 4 is 16. 7 less than 16 is 9.
Answer:
4
Step-by-step explanation:
You can use a simple formula for finding the answer to problems like these. You read it out and put your information in order and use a variable (such as x) in place of the number.
4 * x - 7 = 9
Then solve by getting your variable alone on one side.
Add 7 to both sides: 4 * x = 16
Divide both sides by 4: x = 4
11. The rectangle has a width of 8 in, a length of x-5 in, and an area of 16 in. Solve for X.

16 = 8X – 40
8X = 16 + 40
8X = 56
X= 56 / 8
X= 7 in
I hope I helped you^_^
Answer: x =
Step-by-step explanation:
Area = width times length
8*(x-5)=16
8x - 40 = 16
8x = 16 + 40
x = 56/8
x = 7

The slot size limit for Fish A is from 28 to 32 inches. The minimum size limit for Fish B is 11 inches. Write the ranges of Fish A and Fish B in interval notation and in set-builder notation. Does the range for the Fish B seem reasonable? Explain.
Notations are used to specify the range of a function. The range of fish A is [28,32] while the range of fish B is [11,infinity).
Also, the range of fish B is not reasonable.
For fish A, we have:
[tex]Minimum = 28[/tex]
[tex]Maximum = 32[/tex]
For Fish B, we have:
[tex]Minimum = 11[/tex]
For fish A, the minimum and the maximum are inclusive. So, the range is:
[tex]Range= [Minimum, Maximum][/tex]
This gives:
[tex]A = [28,32][/tex]
For fish B, the minimum is known (and inclusive). The maximum is not known, so we represent the maximum with infinity.
So, the range is:
[tex]Range= [Minimum, Maximum)[/tex]
[tex]B = [11,\infty)[/tex]
The range of fish B is not reasonable because there is a limit to the size of fish a slot can take.

Answer:
Yes they are. Explanation provided below.
Step-by-step explanation:
Two shapes are congruent when they are the same shape and size. Its obvious that both are rectangles and if we look at the grid, we can see that both rectangles are 2 by 4. Since they both have the same shape and size, they are in fact congruent.

A new Community Sports complex is being built in safe harbor the perimeter of the rectangular playing field is 452 yards. The length of the field is 2 yards less than the width. What are the dimensions of the playing field?
Find the Width and the Length
Answer:
Let w = the width
Let 4w - 9 = the length
P = 2l + 2w
582 = 2(4w - 9) + 2w
582 = 8w - 18 + 2w
582 = 10w - 18
600 = 10w
60 yards = w
4w - 9 = 4(60) - 9 = 231 yards
