Answer:
7
Step-by-step explanation:
I like to work liter volume problems in terms of decimeters. 1 dm = 10 cm, and 1 dm³ = 1 L, so the tank is 3 dm by 4 dm by 3 dm = 3×4×3 dm³ = 36 L.
36 liters will support 36/5 = 7.2 platies.
7 platies can be kept in the aquarium.
The greatest commen factor is 4 for both numbers.
To use distributive property you would have to multiply 4 to (3+14) to get the answer.
4(3+14)=68
So,
Let Consuelo's spendings be c and Brenda's spendings be b.
We have our first equation: c = 2b - 3
And our second equation: c = 81
Substitute 81 for c
81 = 2b - 3
Add 3 to both sides
84 = 2b
Divide both sides by 2
42 = b
Brenda spent $42.
Answer:
20 square units
Step-by-step explanation:
The area of a parallelogram is the product of its base length and the height measured perpendicular to the base.
Here, the base is 5 units and the height is 4 units. These can be seen by counting the grid squares.
A = bh
A = (5 units)(4 units) = 20 units²
The area is 20 square units.
Yes, there are many possible answers. An equation that can model your situation is:
4a+4b=75, with a being the amount of adult tickets sold, and b being the amount of children’s tickets sold.
Because both tickets cost 4 dollars, you would multiply the amount of tickets sold, by the price (in dollars) of the ticket.
So, you can find possible answers by substituting the amount of adult tickets sold. Say, 4 adults bought tickets. You could then substitute a for 4. So the equation would look like this.
4(4)+4b=75
16 + 4b = 75
4b = 75 - 16
4b = 59
Divide each side by four
B = 14.75
The reason you got a decimal number is because 75 cannot be divided by 4 evenly. So, in this context, you could say that 15 children bought tickets. One child had an issue, and Lisa gave them a 25% discount. This would explain why there are only 75 dollars worth in tickets. I hope I helped, this is my first question I have ever answered so I’m not entirely sure if this was helpful or not. Hope you figure this out!
