Step-by-step explanation:
In this problem, all we have to do is replace x and y with the values we've been given.
It can be helpful to think of 3x as 3 * x (which is the same exact thing), so I'll write it out that way.
3*x - 4*y
(replace)
3*4 - 4*3
(multiply (doing this step first because of PEMDAS))
12 - 12
(subtract)
0
Answer:
0

Answer:
Pretty sure its 7.5 units²
Step-by-step explanation:
5·3=15÷2=7.5
Doing area with triangles is kind of the same as rectangle, just do base × height. But then divide it by two.
For example: base=3, height=7. With rectangles it would be 21 units².
But with triangles it would be 3·7=21 divided by 2, it would be 10.5 units²
This would be C. the Mode.
In averaging, the mean median and mode each have separate meanings, and the mode is the number which appears most often.
If your string is 8 inches long, and each bead is 2 inches long, you can work out the amount of beads able to fit on the string by doing the following:
Because you have the string length (8 inches) and you know your beads are 2 inches big, you can work it out by doing
8 ÷ 2 = 4
Another way to check this simply doing:
2 + 2 = 4
4 is less than 8 so we know we can keep going
2 + 2 + 2 = 6
6 is still less than 8 so we can do one more
2 + 2 + 2 + 2 = 8
8 is the maximum amount because the length of the string is 8 inches long. Therefore we can see we put 2 in the equation four times, so the answer is 4.
Hope this helped! :)
