Answer:
58 girls, 87 boys
Step-by-step explanation:
145/5 = 29
29*2 = 58 girls
145-58 = 87 boys
Determine a relationship between the x- and y- values. write an equation.
x =1 2 3 4
y = 4 5 6 7Step One: Determine two coordinates written as (x,y)
(1,4) (2,5)
Step Two: Use the formula
Step Three: Simplify to identify the slope
Step Four: Plug your slope (m) into the equation y=mx+b
y = 1x + b
Step Five: Using a coordinate of your choice, plug x and y in to their respective places. (I'm using (1,4))
4 = 1*1 + b
Step Six: Simplify
Step Seven: Isolate b
Step Eight: Rewrite your equation
y = 1x + 3
OR
y = x + 3
(It's more likely you'll see it written the second way)

Answer:
B = 1.875
Step-by-step explanation:
given that A varies directly as B and inversely as C then the equation relating them is
A = ← k is the constant of variation
to find k use the condition A = 12 when B = 3 and C = 2 , then
12 = ( multiply both sides by 2 to clear the fraction )
24 = 3k ( divide both sides by 3 )
8 = k
A = ← equation of variation
when A = 10 and C = 1.5 , then
10 = ( multiply both sides by 1.5 )
15 = 8B ( divide both sides by 8 )
1.875 = B
