<h3>Given</h3>
z = 3
2y +z = 1
2x +3y +2z = 13
<h3>Find</h3>
x, y, z
<h3>Solution</h3>
... z = 3 is given
Substitute that into the second equation.
... 2y + 3 = 1
... 2y = -2 . . . . . subtract 3
... y = -1 . . . . . . . divide by the coefficient of y
Substitute these two solutions into the third equation.
... 2x +3(-1) +2(3) = 13
... 2x = 10 . . . . . . . . . . . . collect terms, subtract 3
... x = 5 . . . . . . . . . . . . . . divide by the coefficient of x
The variable values are: x = 5, y = -1, z = 3
-4.878-(-8.96) can be changed to -4.878 + 8.96 because when you subtract a negative it becomes a positive so the answer would be 4.082 or B
Answer:
16 girls
Step-by-step explanation:
If the ratio Is b:g, then we can assume the majoraty are boys.
If we look at the factors for these numbers, it goes like this: 5, 10, 15, 20, 25 for 4, we get 4, 8, 12, 16, 20, 24. If you look at the fourth factor, 20, and 16, then you can see that they add up to 36.
