Answer:
Hi, there the answer is 2
Step-by-step explanation:
Answer:
42+t
q×10 or Q(10)
x+4
1/2y
Step-by-step explanation:
there are 42 members and their combined total would be the answer
Q is the number of members now, 10 is what you need to times it by in order to get the original number of members
the sister is 4 years younger than her brother, therfor he must be 4+ older than her
half of Y would be 1/2Y
So to find the average, you need to add all of the numbers and divide that by how many numbers there are.
So in this case:
The average weight is 6 lbs
First find Y
using the Pythagorean theorem
y = sqrt (3^2 -1^2)
y = sqrt(8)
y = 2sqrt(2)
now you can use Y to find Z
Z= sqrt( y^2 + 8^2)
z = 6sqrt(2)
the answer is D
