The mean is the average.
Add all the number of pets and divide by how many people there were.
3+5+2+4+1
15/number of people
15/5
=3
Hope this helps :)
Answer:
Because there are fewer than 30 (not no more than 30) one of the answer i x+y < 30
Because he needs both small and large another answer is x>0 and not x 0
Finally because he need at least dozen large cones the last answer is y
Step-by-step explanation:
Step-by-step explanation:
First let solve the inequality
Factor by grouping
So the factor are
So the factor are
and
Solutions to a quadratic can be represented by a absolute value equation because remeber quadratics
creates 2 roots and/or double roots.
The inequality
works as
b is the midpoint between 2 roots. And c is the
We know that the midpoint between both roots is-1/5.
so
Let use roots 3/5
-1 works as well.
So the absolute value equation is
Answer:
137°
Step-by-step explanation:
So, both are equal to each other due to them being the same degree angle.
5x+7=8x-71
subtract 5x on both sides
7=3x-71
add 71 to both sides
77=3x
divide both sides by 3
77/3=x
x equals about 26
insert x into the problems
[5(26)+7]°
this equals 137°
[8(26)-71]°
this equals 137°
