The sum of 'k' and '7' is ' k + 7 '.
Five-sixths of that sum is ' (5/6)(k + 7) '.
The product of '6' and 'c' is '6c' .
"Five sixths of the sum of 'k' and '7' " minus the of '6'and 'c' is
<em> (5/6)(k + 7) - 6c</em>.
Hi, thank you for posting your question here at Brainly. I hope I would be able to help you with my simple explanation:)
To calculate for the volume of a cone, the formula would be
V = 1/3*pi*r²*h
where r = 12 cm, h = 8 cm
So,
V = 1/3*pi*12²*8
V = 384*pi
Answer:
Step-by-step explanation:
3*2x=6x, 3*5=10
So, 6x+10+4x = 5x+15
Add 6 and 4 which leaves you with 10x+10 = 5x+15
subtract 10 from 15 and that leaves you with 5 divided by 10x
x=2
Same for second equation
2*8x=16x and 2*3= 6
So 16x-6=16x+28
Add 6 to both sides so you get 34.
Now that 6 is gone you want x on one side so subtract 16x an it leaves you with 0. so X=34
Answer:
81 girls are in the class
Step-by-step explanation:
in these kinds of questions to find the amount of girls in the class we need to first divide the given number; which in this case is 27, with the starting number; which is 3, and we get 9. Using the 9 we got from the earlier equation we will multiply the 9 by the number of girls in the class, which is also 9 and we get 81 as our answer.
