Answer:
(21+9)+8
Step-by-step explanation:
The associative property allows you to group numbers in different ways.
21 + (9 + 8) = (21+9)+8
Answer:
9+(21+8) or 8+(21+9)
Step-by-step explanation:
Associative property is the property that explains how it does not matter the order of which an equation is multiplied or added by. Switching 9 and 21 will get your answer the same as switching any other number to the outside of the parenthesis.
The amount of water an electric dishwasher uses to wash dishes varies directly with the number of loads of dishes. The dishwasher uses 32 gallons of water to wash 4 loads of dishes.
How many gallons of water will the dishwasher use to wash 10 loads of dishes?
Answer:
It would be 80 gallons of water that the dishwasher will use to wash 10 loads of dishes. To figure this out you would need to divide 32 by 4 which would equal 8. You would do this to figure out how many gallons of water a dishwasher needs to wash 1 load of dishes. Then you would multiply 8 times 10 which would equal 80. Hope this helps you!
Step-by-step explanation:
Answer:
10 loads = 80 gallons of water
Step-by-step explanation:
First, we will be multiplying 4 by 2 so we can get 8loads=64 gallons now we have to find the 2 so divide 32 by 2 which is 16 then finally add them together which will bring 80

Step-by-step explanation:
Write the number 4 2/3 as an improper fraction.
The improper fraction 14/3.
To convert the mixed number 4 2/3 to an improper fraction, we need to find the equivalent fraction where the whole number and fraction parts are combined.
Step 1: Multiply the whole number (4) by the denominator of the fraction (3):
4 * 3 = 12
Step 2: Add the product from Step 1 to the numerator of the fraction (2):
12 + 2 = 14
Step 3: Write the result from Step 2 as the numerator, keeping the same denominator (3):
The improper fraction is 14/3.
Therefore, the mixed number 4 2/3 can be expressed as the improper fraction 14/3.
To understand the result, imagine dividing a whole into 3 equal parts. With 4 wholes, you have 12 parts (4 * 3 = 12). Adding the 2 extra parts (2/3) gives a total of 14 parts out of 3 wholes, which is represented by the improper fraction 14/3.

Dario was scuba diving at an elevation of −20 feet and then descended 20 feet more.
Dario and another person scuba diving. The other person is diving at negative thirty feet.
A number line from negative fifty to fifty by tens is shown.
After the descent, what was his elevation in relation to another diver at an elevation of −30 feet?
Do the equation
Answer:
keep reading
Step-by-step explanation:
Well... Dario is at -40 feet. So the difference would be 10 feet. I don't really know how you would write that equation. But I hope this helped.
The elevation of a diver in relation to another diver at an elevation of −30 feet will be ( -30 + 40 ). The difference between the elevation is 10 feet.
What is a number line?A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R." It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.
Given that Dario was scuba diving at an elevation of −20 feet and then descended 20 feet more. Another diver is diving at -30 feet.
The elevation will be calculated as below:-
Elevation = -30 - ( -40 )
Elevation = -30 + 40
Elevation = 10 feet
Therefore, the elevation of a diver in relation to another diver at an elevation of −30 feet will be ( -30 + 40 ). The difference between the elevation is 10 feet.

How do you algebraically solve for equilibrium using supply and demand equations?
Answer:
How do you find the equilibrium price with a supply and demand function?
To determine the equilibrium price, do the following.
Set quantity demanded equal to quantity supplied:
Add 50P to both sides of the equation. You get.
Add 100 to both sides of the equation. You get.
Divide both sides of the equation by 200. You get P equals $2.00 per box. This is the equilibrium price.

Answer:
It is 80.
Step-by-step explanation:
50% is half and there are 40 blue gumballs in the bag. If you wanted to know the total, you would double 40 because 40 is 50% of the bag, so you are just adding half of it in to get the whole. When you double it, you get 80.
