The first thing we are going to do for this case is define variables.
We have then:
x = Number of boys
y = Number of girls
We now write the system of equations:
x / y = 11/9
x = y + 124
Solving the system we have:
x = 682
y = 558
The number of students is:
x + y = 682 + 558 = 1240
Answer:
the total students in the school is:
1240 students
18 ÷ 2 = 9.
7 x 9 = 63
2/7 = 18/63
Answer:
x = 4y - 4/3
Step-by-step explanation:
Step 1: Write expression
3x + 4 = 12y
Step 2: Subtract 4 on both sides
3x = 12y - 4
Step 3: Divide both sides by 3
x = 4y - 4/3
Answer:
y=2
x=2
y=x2+2
y= lx+2l
Step-by-step explanation:
This is because these are the simplest forms of the equation. seeing as a function is f(x) (which is the same as y) when an equation is equal to a single variable, it is "solved" for hat variable and therefore best represents the equation of the function :)
