What we are going to do with this problem is combine all the like terms.
so to begin, we notice that there are two numbers with a^2 involved, and two numbers with an a.
thus:
8
+(-3
is going to equal
5
because adding a negative is just like subtracting.
then we move on to (6a)-(2a) giving us 4a
5 is the only term that stays the same because there are no other similar terms.
last but not least, put the equation together!
answer: 5+4a+5
Answer:
125 cups can hold 49.5 liters of water.
Step-by-step explanation:
The volume of the cup will tell how much water is needed to fill each cup.
The volume of the cup can be determined by the formula
V= base area* height
V= πr²* h
V= 22/7 (3)² (14)
V= 396cm³
125 cups can hold 125 * 396 cm³= 49500cm³
But 1 cm³= 0.001 Liters
Therefore = 49500*0.001= 49.5 liters
125 cups can hold 49.5 liters of water.
Answer:
The purpose of the the bar diagram is to show the difference between the heights of female and male giraffes, in other words, the bar diagram needs to be able to show how much one value is more or less than the other value.
The height of the males can reach 5.5 meters, and the females' height will only reach 4.3 meters, therefore, we can see that the height of the males are larger than the height of the females, so the equation to find the difference in the heights should be: 5.5 - d = 4.3 (or any other way around).
From that, we know that the height of the males is d meters more than the height of females or the height of the females is d meters less than the height of the males.

For number 1 you want to divide the top number by the bottom number. For example, your fraction is 6/18 so you would do 6 divided by 18. Do this on a calculator for best results!
