What do you mean? I think you need to add a graph with the angles for people to be able to answer that question (you can take a screenshot and then use the paperclip button when you are re-writing the question). Hope this helped.
If you are solving for x than the answer would be x=4.
Mean or Average is all of the sums divided by how many of the choices are there, so all of 10,126+9,99+12,398+12,007+4567=49097 and divided by all the choices you have which is 5 is 9819.4
The Shape in this question is a cylinder
And the formula for finding the L.S.A of a cylinder is 2*pie*r*h
From the question, we are given the diameter so to get the radius we will divide the value for diameter by 2
D = 10/2
=5
Now, 2*3.14*5*4
L.S.A =125.6
Luis spent $9.50, in which:
Candy (y) = $1.25
Chips (x) = $0.50
$9.50 = 1.25y + 0.50x
Luis bought 10 snacks in all
10 = x + y
-----------------------------------------------------------------------------------------------------------------
You're answer:
x + y = 10
1.25y + 0.50x = 9.50
