I will help you because I need points like the answers for 4 huhg
Answer:
540 mins | 9 hours | 540, 9
420 mins | 7 hours | 420, 7
300 mins | 5 hours | 300, 5
180 mins | 3 hours | 180, 3
Step-by-step explanation:
1 hour = 60 mins
To convert hours into minutes, multiply the number of hours by 60 minutes:
9 hours × 60 mins = 540 mins
7 hours × 60 mins = 420 mins
5 hours × 60 mins = 300 mins
3 hours × 60 mins = 180 mins
1=-3x-12
13=-3x
3x=-13
X=-4.33333

Answer:
k = -9.
Step-by-step explanation:
As the triangle is right-angled at Q, by Pythagoras:
PR^2 = PQ^2 + RQ^2
So, substituting the given data and using the distance formula between 2 points:
(7 - 1)^2 + (k - 4)^2 = (-4-4)^2 + (-3-1)^2 + (7 - (-3))^2 + (k - (-4))^2
36 + (k - 4)^2 = 64 + 16 + 100 + ( k + 4)^2
(k - 4)^2 - (k + 4)^2 = 180 - 36
k^2 - 8k + 16 - (k^2 + 8k + 16) = 144
-16k = 144
k = -9.
Answer:
2
Step-by-step explanation:
Write the equation
![\frac{3x-y}{3(x-y)}](https://tex.z-dn.net/?f=%5Cfrac%7B3x-y%7D%7B3%28x-y%29%7D)
Add the variables
![\frac{3(5)-3}{3(5-3)}](https://tex.z-dn.net/?f=%5Cfrac%7B3%285%29-3%7D%7B3%285-3%29%7D)
Multiply 3 x 5
![\frac{15-3}{3(5-3)}](https://tex.z-dn.net/?f=%5Cfrac%7B15-3%7D%7B3%285-3%29%7D)
Subtract the parentheses
![\frac{15-3}{3(2)}](https://tex.z-dn.net/?f=%5Cfrac%7B15-3%7D%7B3%282%29%7D)
Subtract the numerator
![\frac{12}{3(2)}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B3%282%29%7D)
Reduce the fraction with 3
![\frac{12}{3(2)} = \frac{4}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B3%282%29%7D%20%3D%20%5Cfrac%7B4%7D%7B2%7D)
Reduce the fraction again with 2
![\frac{4}{2} = 2](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B2%7D%20%3D%202)
And there's your answer of 2!
