There are 27 boys on the playground.
Step-by-step explanation:
No. of Pre-K children = 34
No. of kindergarten children = 29
Total no of children = 29+34 = 63
Ratio of boys to girls = 3:4
Total ratio = 3+4 = 7
Therefore,
boys proportion =
Total number of boys =

Answer:
Step-by-step explanation:
The equation of the line WX is, 2x + y = - 5
⇒ y = - 2x - 5 .......... (1)
This equation is in slope-intercept form and the slope is - 2 and the y-intercept is - 5.
Now, if a line perpendicular to equation (1) having slope m then, m × (- 2) = - 1
⇒
{Since the product of slopes of two mutually perpendicular straight line is - 1}
Therefore, the equation of the perpendicular line is
, where c is a constant and we have to find it.
This above line passes through the point (-1,-2) and hence
⇒
Therefore, the equation of the line will be (Answer)
