Answer:
Choice 2
Step-by-step explanation:
When finding the volume of a 3D shape, your answer will always result in being units to the 3rd power.
4k-7=2k+3
-2k. -2k
2k-7=3
+7. +7
2k=10
2÷2 2÷10
k=5
4(5)-7=13
Answer D
Answer:
347
Step-by-step explanation:
i added them all
Basically what you need to do is find a common denominator between 4 and 5. The answer would be 20. That would be the denominator. If you are multiplying 3/5 to get to twenty multiply 5x4=20. 3x4=12. You need to do the same thing to the numerator . Same for 1/4 multiply by 5. 4x5=20. 1x5=5 so, you would add 2 5/20 and 4 12/20. You would get 7 17/20 if you do it correctly :)
Answer:
5/8
Step-by-step explanation:
So, if we add 7 + 12, then it seems that 19 of the 24 students play one of the two sports. But there are 4 students that play both, so we must account for that.
To get the actual number of students that play sports, we must subtract 4 from 19.
19 - 4 = 15
So now we know that 15 out of the 24 students play sports.
We can divide 15 and 24 by 3 to find the simplified fraction.
15 / 3 = 5 24 / 3 = 8
So 5 out of every 8 students plays one of these sports, which means that the probability of picking one of these students is 5/8!
