Forget it, i'm confused
Step-by-step explanation:
(3x+2)+(5x-5)=8x-3
(17x-7)-(8x-3)=9x-10
Double Check
9x-10+5x-5+3x+2
17x-15+2
17x-13
Answer:
The value of <em> </em>
= 3
Step-by-step explanation:
<u><em>Explanation</em></u>
<em>Given </em><em></em>
<em></em>
<em>L.C.M 8 , 12 is 24</em>
<em> </em>
<em> </em>
<em></em>
<em> = </em>
<em></em>
<u><em>Final answer</em></u><em>:-</em>
The value of <em> </em> = 3
To mountains took 9 Hrs at x mph where x = No of miles to mountains
No of miles travelled = 9x
From mountains took 4 hours at (x+40) mph
No of miles travelled = 4(x+40)
Therefore 9x=4(x+40) thus 9x=4x+160 thus x=32 = distance Charmaine lives from the mountains
Answer:
a) 165.52 degrees.
b) 131.41 degrees.
c) 118.96 degrees.
d) 159.73 degrees.
Step-by-step explanation:
The sine of an obtuse angle is positive as it is in the second quadrant.
a) Using a calculate the angle whose sine ( arcsin) is 0.25 = 14.478 degrees
so the obtuse angle = 180 - 14.478 = 165.52 degrees to nearest hundredth
b) c) and d) are calculated in the same way.
