Answer:
-4
Step-by-step explanation:
We have the coordinates (6, 3) and (8, 4), allowing us to calculate the slope (or gradient). To do this, you divide the change in y by the change in x, which is 1/2 which is a half.
The form of a linear equation is y = mx + c, where m is the gradient and c is the y-intercept.
We have the gradient, so we can put it in the equation:
y = x/2 + c
We can now substitute in a pair of our coordinates and rearrange to find the y-intercept.
3 = 6/2 + c
3 = 3 + c
c = 0
Therefore the equation for our line is y = x/2.
We can now put in the y coordinate we were given to work out the corresponding x coordinate:
-2 = x/2
x = -4
Therefore n is -4.

Answer:
213
Step-by-step explanation:
convert percent to decimal 48%=0.48
144x0.48= 69.12
estimate 69.12 we got 69
144+69=213
Answer:
applying trigonometry
base= 30inches
height= 50inches
angle between ladder and ground = 59.04°
for the length of the ladder...
sin59.04 = opposite side ÷ hypotenuse
sin59. 04 = 50inches ÷ hypotenuse
0.8575 = 50 inches ÷ hypotenuse
cross multiply;
hypotenuse = 50inches ÷ 0.8575
the length of the ladder = 58.309inches
