Answer:
x=-5
Step-by-step explanation:
10x + 15 = 5x-10
-5x -5x
5x+15 = -10
-15 -15
5x = -25
/5 /5
x = -5
The answer to this should be a-8b+13c
a - {4b - [a - (5b - c) + 3c - (a - b - 9c)]}
=a - {4b - [a - 5b + c + 3c - a + b + 9c]}
=a - {4b - [- 4b+ 13c]}
=a - {4b + 4b -13c}
=a - 8b + 13c
Hope this helped :)
Have a great day
The general equation is: f(t)= 
The given equation is: f(5)=288.9 when r = 0.05
Following the general equation, we know the following:
t=5, r = 0.05 and
= 288.9
Substituting all unknowns, we can solve for p
= 288.9
Solving for p,
p = 225
Answer:the distance from the headquarters from a point on the ground directly below the balloon is
175 feet
Step-by-step explanation:
The right angle triangle ABC formed is shown in the attached photo. C represents the position of the balloon.
A represents the position of the ranger headquarters.
x represents the distance from the headquarters from a point on the ground directly below the balloon.
1 minute = 0.0167 degrees
Converting 43' to degrees, it becomes 43 × 0.0167 = 0.7181
Angle A = 66 + 0.7181 = 66.7181 degrees.
We would apply trigonometric ratio
Tan # = opposite side/ adjacent side
# = 66.7181 degrees.
opposite side = 1106
Tan 66.7181 = 1106/x
6.324 = 1106/x
x = 1106/6.324
x = 175 feet
