Answer:
78
Step-by-step explanation:
Let x be the score on the next test
We are averaging 6 tests and want an average of 75
( 82+91+38+78+83+x) /6 = 75
Multiply each side by 6
( 82+91+38+78+83+x) = 75*6
( 82+91+38+78+83+x) =450
Combine like terms
x+372 = 450
Subtract 372 from each side
x+372-372 = 450-372
x =78
Step-by-step explanation:
Consider the provided information.
We have given that H and k are the subgroups of orders 5 and 8, respectively.
We need to prove that H∩K = {e}.
As we know "Order of element divides order of group"
Here, the order of each element of H must divide 5 and every group has 1 identity element of order 1.
1 and 5 are the possible order of 5 order subgroup.
For subgroup order 8: The possible orders are 1, 2, 4 and 8.
Now we want to find the intersection of these two subgroups.
Clearly both subgroup H and k has only identity element in common.
Thus, H∩K = {e}.
I thinks it’s B but not 100%
Answer:
The sum of 68 and 14 = 82
The product of 56 and 65 = 3640
The difference between 78 and 24 = 54
The quotient of 648 and 13 = 49.84
65 multiplied by 45 = 2925
Find the quotient of 230 and 5, then add 47 = 93
Subtract 43 and 12, then divide by 3 = 10.33
Find the product of 681 and 23, then subtract by 4 = 15659
Add 9 to the difference of 19 and 8 = 20
Multiply the sum of 87 and 16 by 13 = 1339
Subtract 56 from the product of 58 and 42 = 2380
Add 99 to the quotient of 850 and 10 = 184
Answer:
Step-by-step explanation:
hello :
the ratios 2:1 and 18:9 are equivalent because :
2/1 = (2×9)/(1×9)= 18/9
