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
Answer:
It shows how a dimension in a scale drawing is related to the actual object. A map is a scale drawing. The measurements on a map are in proportion to the actual distances. If 1 inch on a map equals an actual distance of 2 miles, the scale is 1 inch = 2 miles

Answer:
46
Step-by-step explanation:
For the value of y, substitute x = 28 into the equation.
2x + 3y = 194
2(28) + 3(y) = 194
56 + 3y = 194
3y = 194 - 56
3y = 138
dividing bothsides by 3
y = 46
Answer:
3
