Well the first one you have to divide both sides by 60 to get x.
=60x/60=1500/60
x=25
your answer is 25%
second one...think of it as 18/50. multiply by 2 and you get 36/100
your answer is 36%
Answer:CR= 53
AB = 118
CAB = 236
Step-by-step explanation: a whole is circle is equal to 360 degrees and when you see the two parts which dint have an angle, they look the same size. So I pluses 53 and 71 than subtracted from 360. Which then I divided it by two then you get the angle for A to B.
Hope this helped and hope this is the correct answer.
No because 4/1 does not equal to 9/4 or 16/9

Answer: -19, -15, -9, -1, 9 (choice A)</h3>
===================================================
Explanation:
If we plug in x = -2, then we get,
y = x^2 + 7x - 9
y = (-2)^2 + 7(-2) - 9
y = 4 - 14 - 9
y = -10 - 9
y = -19
So x = -2 leads to y = -19. The answer is between A and D.
---------
If you repeat those steps for x = -1, then you should get y = -15
Then x = 0 leads to y = -9
x = 1 leads to y = -1
Finally, x = 2 leads to y = 9
The outputs we get are: -19, -15, -9, -1, 9 which is choice A
Choice D is fairly close, but we won't have a second copy of -15, and we don't have an output of -19.
