Step-by-step explanation:
-12x+8+5x=39
-12x+5x+8=39
-7x+8=39
-7x=39-8
-7x=31
-7x/-7=31/-7
x=31/-7
is the equation in the question written like the one in the bottom? Because for me to help you I must confirm what the equation looks like.
× ![\frac{4a-14}{a+3}](https://tex.z-dn.net/?f=%5Cfrac%7B4a-14%7D%7Ba%2B3%7D)
Cosec θ = 1.6981
1/sin θ = 1.6981
sin θ = 1 / 1.6981 = 0.5889
θ = arc sin 0.5889 = 36.1 degrees
Answer:
The least common multiple is 2y^2 - 50.
Step-by-step explanation:
Least common multiple means the lowest thing you can multiply them both to. For example, the LCM of 2 and 4 is 2, because 2*2 = 4 and 4*1 = 4.
First, factor 2y^2 - 50.
2 (y^2 - 25)
2 (y - 5)(y + 5)
Looks like if we wanted to get 2y^2 - 50 starting with y - 5, we'd have to multiply it by 2(y + 5).
2y^2 - 50 * 1 = 2y^2 - 50
y - 5 * 2(y + 5) = 2y^2 - 50
<u>So their least common multiple is 2y^2 - 50.</u>
Answer:
Step-by-step explanation:
Let the number of minutes in 6.1 hours be x. Remember that there are 60 minutes in one hour. Therefore,
If 60 minutes = 1 hour,
Then
x minutes = 6.1 hours
Cross multiplying, it becomes
x × 1 = 6.1 × 60 minutes
x = 6.1 × 60 minutes/1
Therefore, the correct ratio with which 6.1 hours would be multiplied is
60 minutes/1 hour
