Answer:
1:3.2km
Step-by-step explanation:
-Given the scale 1:320000 all in centimeters.
-We need to convert the represented cm dimension into kilometers.
#We know that 1cm equals 0.00001 km.
We therefore multiplied the represented dimension by 0.00001 km:

Hence the scale i s 1cm represents 3.2km thus 1:3.2km

I'll be online so let me know if you still need help.
Step-by-step explanation.
A system of equations is basically two or more equations that rely on each other. If a solution for a variable is 2, it has to work for the other equation.
The substitution is basically plugging in the y value to y = 8x + 10
If y = 2
and also y = 8x + 10
What do you think the substitution is?
Answer:
There are 406 students in the school
Step-by-step explanation:
Let the number of students in the school be x
The total ratio is 11 + 3 = 14
The ratio that buys lunch is represented by 3
So, we have it that;
3/14 * x = 87
3x = (14 * 87)
x = (14 * 87)/3
x = 406
