Answer:
87 percent leave room for unexpected variations
So for every two girls, there's four boys. There are twice as many boys than girls, so the number of girls • 2 = your answer.
51 • 2 = 102
Answer:
18x + 13y = 60
6x + 2y = 6 ---> 6x = -2y +6 ---> 18x = -6y+18
Substitution
(-6y +18)+13y =60
-18 -18
--------------------------
7y = 42 so y=6
Then, 6x + 2(6) =6, which you will get x = -1
(-1, 6)
Answer:
The y-intercept is (0, 1/2)
The x-intercept is (0, -8)
Answer:
4x+3y=68
9x+2y=77
