Answer:
In 4 months, they will both have 132 stamps.
Step-by-step explanation:
Let x = # of months
52 + 20x = 68 + 16x
4x = 16
x = 4
Plug x value into both expressions and see if it checks out
52 + 20(4) = 68 + 16(4)
52 + 80 = 68 + 64
132 = 132

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.
Hint: label the figure.
K-5in
8in
Area = width × length
16= 8 × (X –5 )
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
Solve the equation.

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

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.

circumference of 2 pie x 110
Answer:
The circumference of the circle A = 110 cm and the circumference of the circle B = 132 cm
Step-by-step explanation:
Circumference of circle A = 2πr = 110
[2×(22/7)×r ]= 110
r = (7×5)/2 = 17.5 cm.
Circumference of circle B = 2πR = 132

s =
Answer:
s=5
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
s=5
Answer:
s = 5
Step-by-step explanation:
1.52(s + 3) − 2.61 = 9.55
solve the brackets first
1.52s + 4.56 − 2.61 = 9.55
1.52s + 1.95 = 9.55
1.52s = 9.55 - 1.95
1.52s = 7.6
s = 7.6 / 1.52
s = 5
Let's Cross-Check
1.52 (5 + 3) − 2.61
7.6 + 4.56 − 2.61
7.6 + 1.95

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $77. A season ski pass costs $450. The skier would have to rent skis with either pass for $20 per day. How many days would the skier have to go skiing in order to make the season pass less expensive than the daily passes?
Answer:
5
Step-by-step explanation:
Given:
Daily pass = $77Season ski pass = $450Skis = 2077 + 20 = 97
450 + 20 = 470
Keep multiplying 97 with random numbers until it passes 470.
97 × 4 = 388
97 × 5 = 485
So, the skier will have to pay daily passes 5 times to be more expensive than the season pass.
Hope this helped.

Evaluate the equation 2L+6=6L-10
Answer:
2
Step-by-step explanation:
2L + 6 = 6L - 10 Add 10 to both sides
2L + 6 + 10 = 6L Combine the left.
2L + 16 = 6L Subtract 2L from both sides
16 = 6L + 2L Combine the right
16 = 8L Divide by 8
8L = 16
8L/8 = 16/8
L = 2
