The length= x
The width= y
Perimeter is 28 cm, so...
Equation 1
x+x+y+y=28
2x+2y=28
x+y=14
x=14-y
Length is 10 com longer than width, so...
Equation 2
x-y=10
Substitute Equation 1 into Equation 2
x-y=10
14-y-y=10
-2y=-4
y=2
Substitute y=2 into Equation 1
x=14-y
=14-2
=12
Answer: Length=12 cm, Width=2 cm
Final answer:
The length of the rectangle is 12 cm and the width is 2 cm.
Explanation:
To solve this problem, you have to understand that the perimeter of a rectangle is given by the formula 2(length + width). You are given that the perimeter is 28 cm, and the length is 10 cm longer than the width. Let's denote the width as 'w'. So, the length would be 'w + 10 cm'. Substituting into the formula, we have:
2((w + 10) + w) = 28
which simplifies to:
2(2w + 10) = 28
4w + 20 = 28
Subtract 20 from each side:
4w = 8
Finally, divide each side by 4 to solve for 'w':
w = 2 cm. The width is 2 cm and the length, which is 10 cm more than the width is 12 cm.

Answer: To find the best estimate for the amount of money Megan has left, we need to subtract the amount she spent from the initial amount she had. Megan started with $45.12, and she spent $7.89 for lunch and $21.25 for sunglasses.
First, let's subtract $7.89 from $45.12:
$45.12 - $7.89 = $37.23
Next, let's subtract $21.25 from $37.23:
$37.23 - $21.25 = $15.98
So, the best estimate for the amount of money Megan has left is $15.98.
Out of the given options, the closest estimate to $15.98 is $16. Therefore, the correct answer is $16.

$16

Keep in mind the distributive property:
a(b + c) = ab + ac
a(b - c) = ab - ac
So, apply the distributive property to get:
4(2x) + 4(3) = 2(3x) - 2(4)
Simplifying that more, we get:
8x + 12 = 6x - 8
Subtract 6x on both sides
8x + 12 - 6x = 6x - 8 - 6x
8x - 6x + 12 = -8
2x + 12 = -8
Subtract 12 on both sides
2x + 12 - 12 = -8 - 12
2x = -8 - 12
2x = -20
Divide by 2 on both sides
2x/2 = -20/2
x = -20/2
x = -10
There is only one solution, so your answer is A. one solution.

Pool A.
Step-by-step explanation:
This can be solved through ratios. You would write it as So,
for the first one, and
for the second. You might want to use a calculator for that part, but you could also change the gallons to cups, which gives you a much better number of 10.515. So,
, and
So, pool A is at a faster rate. If you want it in gallons per minute, it's by 0.01 (with the 1 repeating) gallons per minute. By cups, it's 0.17525 cups per minute.
(The reason I did not do this by cross multiplying and dividing ratios is because it gives you the exact same answer if you are finding it per one, as I am here with per one minute. You can do it this way, it just wastes a bit of time.)

Answer:
C
Step-by-step explanation:
We know that 35 employees are currently at the company and this is constant. If the employees, e, increases by a factor of 5 each month for 4 months. Therefore the equation should be :
The equation only accounts for the employee total increase after 4 months
