hello
step 1,
convert the hour time to minute
![\frac{1}{10}h=\frac{60\min s}{10}=6\min s](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%7Dh%3D%5Cfrac%7B60%5Cmin%20s%7D%7B10%7D%3D6%5Cmin%20s)
step 2
find the rate
- 1 3/5= -8/5 ( Multiply the denominator and whole number ) -1*5= -5 -3= -8
-8/5 ÷ -5/6
-8/5*-6/5 ( whenever dividing flip over the second fraction )
=48/25 ( whenever multiplying - negative and - negative = + positive number
48/25= 1 23/25
Answer :48/25 or 1 23/25
Answer:
90
Step-by-step explanation:
x-35=55
add 35 on each side
x=90

Answer:</h2>
For ∠1: Because all angles inside a triangle equal 180°, set ∠2, 68, and ∠1 equal to 180, then solve for ∠1.
![x + 68 + 49 = 180\\\\x + 68 = 131\\\\x = 63](https://tex.z-dn.net/?f=x%20%2B%2068%20%2B%2049%20%3D%20180%5C%5C%5C%5Cx%20%2B%2068%20%3D%20131%5C%5C%5C%5Cx%20%3D%2063)
∠1 = 63°
For ∠3: Subtract 93 from 180 to get ∠3
![x + 93 = 180\\\\x = 87](https://tex.z-dn.net/?f=x%20%2B%2093%20%3D%20180%5C%5C%5C%5Cx%20%3D%2087)
∠3 = 87°
For ∠4: Because all angles inside a triangle equal 180°, set ∠3, 49, and ∠4 equal to 180, then solve for ∠4.

![x + 49 + 87 = 180\\\\x + 49 = 93\\\\x = 44](https://tex.z-dn.net/?f=x%20%2B%2049%20%2B%2087%20%3D%20180%5C%5C%5C%5Cx%20%2B%2049%20%3D%2093%5C%5C%5C%5Cx%20%3D%2044)

∠4 = 44°
∠2 = 49°
