Step-by-step explanation:
angle ABC= angle ACB= 37° --------- because AB=AC
angle ACB+ angle ACD=180°
37+angle ACD=180
angle ACD=143°
Answer:
Step-by-step explanation:
to solve this you would subtract 100 from each side :
Y = 100+50x
-100 -100
-100= 50x
then you would divide each side by 50 to get 'x'
-100/50=50x/50
-2 = x
Answer:
-167.2 ft/mile
Step-by-step explanation:
The "rise" is 1298 -1776 = -478 ft. The run is given as 15,098 ft, so the slope is ...
slope = rise/run = -478/15098 ≈ -0.0316598
For 5280 feet in 1 mile, that rate of change amounts to ...
-0.0316598×5280 ft ≈ -167.2 ft . . . per mile
X² + 11x + 24 = 0
24*1 = 24
We think of 2 numbers that multiply to give 24 and add up to give 11
The 2 numbers are 8 and 3.
8*3 = 24 and 8 + 3 = 11
So the 11x in x² + 11x + 24 = 0
Replace 11x with (3x + 8x)
x² + 11x + 24 = 0
x² + 3x + 8x + 24 = 0 Factorize.
x(x + 3) + 8(x + 3) = 0
(x + 3)(x + 8) = 0
That means:
x + 3 = 0 or x + 8 = 0
x = 0 - 3 x = 0 - 8
x = -3 or x = -8
Therefore: x² + 11x + 24 = 0 is (x + 3)(x + 8) = 0 and x = -3 or x = -8
Hope this helps.
2,50 + 4 + 4,25 + 3,25 = 14$
6/14 = 3/7 = 42,8% increase
