It’s 25. All u need to do if your confused is skip count by 5 until you get to 25. 5,10,15,20,25 that’s 5 counts.
Answer: Actual distance = 37.5 miles
Step-by-step explanation:
<u>Let x be the actual distance</u>
<u>Given information</u>
Length on map = 7.5 inches
Scale = 1 inch : 5 miles
<u>Set up proportion</u>
![\frac{7.5}{x} =\frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B7.5%7D%7Bx%7D%20%3D%5Cfrac%7B1%7D%7B5%7D)
<u>Cross multiply to convert out of fraction form</u>
![7.5*5=1*x](https://tex.z-dn.net/?f=7.5%2A5%3D1%2Ax)
![\boxed{x=37.5}](https://tex.z-dn.net/?f=%5Cboxed%7Bx%3D37.5%7D)
Hope this helps!! :)

Answer:
x = π/6, π/2, 5π/6, 3π/2
Step-by-step explanation:
cos x = sin(2x)
Use double angle formula.
cos x = 2 sin x cos x
Move everything to one side and factor.
cos x − 2 sin x cos x = 0
cos x (1 − 2 sin x) = 0
Set each factor to 0 and solve.
cos x = 0
x = π/2, 3π/2
1 − 2 sin x = 0
sin x = 1/2
x = π/6, 5π/6
The total solution is:
x = π/6, π/2, 5π/6, 3π/2
The answers are:
x= -5
y= -1
This is how I solve my equations.......
