Answer:
<h3> D){?}
x = 7</h3>
Step-by-step explanation:
x + 3•(+1) = 2•x + 4•(-1)
x + 3 = 2x - 4
-3 -3
x = 2x - 7
-2x -2x
- x = -7
÷(-1) ÷(-1)
x = 7
Multiply num and dem by 2 each to get 8/20
The answer is 10
10-1=9
9*8=72
Answer:
I got x1 =0 x2=220
Step-by-step explanation:
y=- 00.1x (x-220)
-0.01x (x-220)=0
- 1/100 x(x-220)=0
x (x-220)=0
x=0
x-220=0
Answer x=0 and x=220
Answer:
70.9 feets
Step-by-step explanation:
From trigonometry:
tan θ = opposite /Adjacent
Opposite = tree height, y
Adjacent = vertical distance between eyelevel and tree
tan 33º = y/100
y = 100 * tan 33º
y = 100 * 0.6494075
y = 64.9 feets
Distance between John's eye level and the ground = 6 feets
Total tree height = 6 + 64.9 = 70.9 feets
