Four is greater than y, and -1 is less than y

Answer:
A. 6^2/7 and (√6)^7
Step-by-step explanation:
Because we can't get 6 out of root as a whole we need to use the power to show its value when we do so.
The power of (√6)^7 has is seven and degree of the root is 2 so we have to put 2/7 over 6 when we take it out of root.
The sum in sigma notation for the sequence will be as follows:
From
<span>5 + 10 + 15 + 20 + 25 + 30 + 35 + 40 + 45 + 50
first term=5
common difference=5
number of terms=10
n=nth term
thus the sum will be:
(i=2 to 10)</span>∑(5(n-1)+5)
Answer:
s = 180
Step-by-step explanation:
s is the total number of seventh-grade students
1/10s take French which is 18
1/10s = 18
s = 18(10)
s = 180
