Answer:
- 5
Step-by-step explanation:
The equation of a line in slope - intercept form is
y = mx + c ( m is the slope (gradient) and c the t- intercept )
y = 3x - 8 ← is in slope- intercept form
with gradient m = 3 and y- intercept c = - 8 , thus
m + c = 3 + (- 8) = 3 - 8 = - 5
25 kids in all
2xboys:3x girls
so the equation would be
2x+3x=25
solve,
5x=25
/5 /5
x=5
2x=10
3x=15
10 boys and 15 girls
For #1 the answers are
69 degrees
155 degrees
86 degrees
335 degrees
249 degrees
multiply width times the height to get the rectangle area
5 x 7 = 35 units squared
I may be wrong but I think you may be over complicating it its okay I do that a lot too
