Answer:
a. 80 students
b. 92 students
Step-by-step explanation:
Represent arts students with A and Dance students with D.
So, we have,
n(A) = 35
n(D) = 57
Required
Determine n(A or D)
Solving (a):
Here, we have:
n(A and D) = 12
n(A or D) is calculated as thus:
n(A or D) = n(A) + n(D) - n(A and D)
n(A or D) = 35 + 57 - 12
n(A or D) = 80
b. From the given details
n(A and D) = 0 because both students are not mixed up as in (a) above
Using the same formula as (a).
n(A or D) = n(A) + n(D) - n(A and D)
n(A or D) = 35 + 57 - 0
n(A or D) = 92

Answer: See explanation
Step-by-step explanation:
a. 19 > x + 4
Collect like terms
= 19 - 4 > x
= 15 > x
= x < 15
b. 5x > 4x - 9
Collect like terms
5x - 4x> -9
x > -9
Answer:
68, assuming that there are four bears packed into each case.
Step-by-step explanation:
Assuming that "compatible" means "reasonable" here, and that we assume that each case holds four teddy bears, then the total number of bears in the shipment is (17 cases)(4 bears per case) = 68 bears
