7j + 17 = 87
Subtract 17 from both sides.
7j = 70
Divide both sides by 7.
j = 10
<h3>The value of the unknown number, or j, is equal to 10.</h3>

Answer:
The radius of cylinder is 8 inches.
Step-by-step explanation:
We have given,
Volume of cylinder = 320π cubic inches
Height of cylinder = 5 inches
We know, Formula for volume of cylinder as : V =πr²h
where r is radius of cylinder and h is the height of cylinder.
So, We can plug values for V and h to get radius of cylinder.
i.e V = πr²h
320π = πr²* 5
Solving for r.
We get,
320 = r² * 5
320/5 = r²
64 = r²
or r = ±8 , Since radius of cylinder can not a negative number so we neglect -8.
Hence the radius of cylinder is 8 inches.

Answer:
At least 7 more students need to sign up for the field trip to be scheduled
Explanation:
Assume that the least number of students remaining to register for the trip to be scheduled is x.
total number of students = students who already registered + x
We are given that, the least number of students required for this trip is 30. This means that:
total number of students ≥ 30
Now, we know that 23 students already registered.
The inequality now is:
x + 23 ≥ 30
x ≥ 30 - 23
x ≥ 7
This means that at least 7 more students must register for the trip to be scheduled.
Hope this helps :)
Answer:
Step-by-step explanation:
Hello, we can notice that f(-1)=0 so (x+1) is a factor and we can write.

The sum of the zeros is 8=6+2 and the product is 12=6*2
So the zeroes are 2, 6, -1
