8+(x/-9)=9 subtract 8
x/-9= 1 multiply by -9
x= -9
Answer:
72 km
Step-by-step explanation:
We can use basic logic to find how many miles you run in 12 weeks.
If you run for 2 km 3 times a week, then you run 6 km per week because 
.
If you continue this for 12 weeks, that means you will have ran 
km, which can simplify down to 72 km.
Hope this helped!
5. The reason you would need 5 cups is simple. For 48 cookies you need 3 cups of flour meaning that 48/3 is 16 cookies PER CUP. In order to find out how many cups is needed for 80 in simple. You found out that 1 cup of flour makes 16 cookies. Divide 80 by 16 (80/16) and you get 5. You would need 5 cups of flour.
The elevation of the plane is 3600 ft
Let
- h = elevation of plane,
- d = distance from Marsha's house to spot on ground below plane = 3600 feet and
- Ф = angle of elevation of plane = 45°
From the triangle, we have the trigonometric ratio
tanФ = h/D
<h3>Elevation of the plane</h3>
Making h subject of the formula, we have
h = DtanФ
substituting the values of the variables into the equation, we have
h = DtanФ
h = 3600 ft × tan45°
h = 3600 ft × 1
h = 3600 ft
So, the elevation of the plane is 3600 ft
