3=-5
(not 100% sure, just basic math)
You want the minimum of the solutions to
x + y = 24
7x - y = 16
There are many ways to solve these equations. Adding them together, you get
8x = 40
x = 5
Since this value is less than 12, it is the smaller number. The smaller number is 5.
Answer:

Answer:
P(green) =1/4
P(orange)=1/2
Step-by-step explanation:
I'm assuming this is probability but it\s been a while, so i'm not sure
number one is a square being divided into half and then one half is being divided into quarters. (as shown by the dotted lines and right angle)
so the probablity of landing in green is 1/4, because it is one fourth of the square.
the probability of the orange is 1/2 because it is 1/2 of the square
The same logic would apply to the "circle" i can see in the next problem. 120 degrees is 1/3 of 360, 90 is 1/4, and so on.
Hope that helps.

The formula for the area of a circle is:
π*radius^2
Input the information we already know:
π*5^2
Follow BEDMAS
π*25
=78.5398163
Since half of the circle is shaded, divide the area by 2
78.5398163/2
=39.2699081
The area of the shaded sector is 39.2699081 meters²
