Multiply both sides of the first equation by 3.
Multiply both sides of the second equation by 2.
6x + 9y = 3
-6x - 4y = -2
Now add them.
5x = 1
x = 1/5
Now plug in 1/5 for x in the first original equation.
2x + 3y = 1
2 * 1/5 + 3y = 1
2/5 + 3y = 1
2 + 15y = 5
15y = 3
y = 1/5
The solution is x = 1/5; y = 1/5.
There is one solution.
Answer:
that's hard bro what grade are you in
To find total number of girls multiply total students by the fraction of girls:
360 x 4/9 = 360 x 4 = 1440/9 = 160 total girls.
If 3/5 are below the age of ten, that means 2/5 are above the age of ten.
Multiply the total number of girls by 2/5:
160 x 2/5 = 320/5 = 64
There are 64 girls above the age of ten.
(4,-1)
If you graph 0,-1 as a coordinate then x=2 you can just count how many are before the line, then count that many after and that’s your coordinate
