Answer: Team one = 1/5
Team 2 = 4/21
Team A is the fastest
Step-by-step explanation: Answer: Team one = 1/5
Team 2 = 4/21
Team A is the fastest
Step-by-step explanation: TEAM A
Tammy working alone in 1hr can clean 1/2
Melissa working alone in 1 hr can clean 1/3
working together in 1hr ,let x represent the area they will clean we have
+ = 1/x
⇒ 3 + 2 = 1/x
5 = 1/x
x = 1/5
TEAM B
Santay working alone can clean 1/4
Leticia working alone in 1 hr can clean 4/5
working together in 1 hr ,let y represent the amount they clean, we have
+ = 1/y
4 + 5/4 = 1/y
21/4 = 1/y
y = 4 /21
comparing x and y , 1/5 is greater than 4/21 , therefore Team A is faster
Answer:
The height of the tank is 20 inches.
Step-by-step explanation:
The fish tank is a parallelepiped wich volume equals to the product of it's three dimensions, the width, length and height. So the formula to the volume is:
V = width*length*height
In this problem we know the volume, the width and the length and we want to know the height, so we can isolate the variable we want to know, such as:
height = V/(width*length) = 3360/(14*12) = 3360/168 = 20 inches
The height of the tank is 20 inches.

The ratio is ...
carrots : cucumbers = 3 : 9 = 1 : 3
The fewest number of vegetables that can be used is 1 carrot and 3 cucumbers, a total of 4 vegetables.
280 names the same amount to 1 hundred 4 tens and 14 tens because
100 + 40 + 140 = 280
Hope this helps!!
Add 6 on both sides, canceling out that -6
3x = 21
Divide both sides by 3 to isolate that variable and get your answer
x = 7.
