There are several important information's already given in the question. Based on those given information's the answer to the question can be easily deduced.
Total number of students in the school = 209
Ration of the boys to girls in the school = 6:5
Let us assume the common ratio to be = x
Then
6x + 5x = 209
11x = 209
x = 209/11
= 19
Then
The number of girls in the school = 19 * 5
= 95
So there are a total of 95 girls in the school that has a total of 209 students.

Slope-intercept form: y = mx + b [m is the slope, b is the y-intercept or the y value when x = 0 ---> (0, y) or the point where the line crosses through the y-axis]
To find the slope, use the slope formula (m):
and plug in the two points
(6, 8) = (x₁, y₁)
(9, 6) = (x₂, y₂)
Now that you found the slope, plug it into the equation
y = mx + b
To find b, plug in one of the points, I will use (6, 8)
8 = -4 + b Add 4 on both sides
12 = b Now plug in b into the equation

Step-by-step explanation:
Answer:
A) 5 and B) 5
Step-by-step explanation:
A) 5x-12=13
+12 +12 (add 12 to the 13)
5x=25
(then divide 25 by 5 which is 5 so the answer is 5)
B) 8(x+3)=64 (first use distributive property)
8x+24=64
-24 -24 (then subtract 24 to 64 which is 40)
8x=40
(then divide 40 by 8 which is 5 so that is it!)
I believe this is correct, I hope this helps :D
