-1, -1/2, -2 so solve it like this on the numberline
Answer:
If 9 of the sparrows is 45% of the birds in the backyard, 9/x = 45/100.
Cross multiply to get 9 * 100 = 45x; simplified is 900 = 45x or 20.
This means that there are 20 birds in the backyard. You can check this by dividing 9/20 which equals 45%
none??' you mean nine?
Let the unknown number be x.
5/11 * x = 55
Since x is being multiplied by 5/11, and you want x alone, you need to multiply both sides of the equation by the reciprocal of 5/11 which 11/5.
11/5 * 5/11 * x = 55/1 * 11/5
x = 605/5
x = 121
Answer: The number is 121.
ANSWER: 1:42 PM
First find how many hours 71/2 hours is. Half of 71 is 35.5. Do one day back... So 35.5 hour becomes 11.5 hours and 2:12 AM still stays the same. Now take away 30 min (0.5) from 11.5 hours and from 2:12 AM. Now the numbers are 11 hours and 1:42 AM. Subtract 1 hour from both amounts, 10.5 hours and 12:42 PM. Now, subtract 11 hours from both amounts again. 0 hours left and 1:42 PM.
Equation in point slope form is given by y - y1 = m(x - x1); where m = (y2 - y1)/(x2 - x1).
y - 0 = (6 - 0)/(2 - 4) (x - 4)
y = 6/-2 (x - 4)
y = -3(x - 4)
