Answer:
1. 88 - b
Since there is 88 birds and a few of them flew away. You know b represents the amount of birds present.
2. 73 + d
Since he is earning d (amount of dollars) so what you have to do is add the amount of dollars, d, to the orginial amount, which is 73.
3. 23 x g
Since Kurt has 23 miles. If he drives 23 miles to a gallon and we have g gallons then we would multiply to find how far he can drive.
Answer:
4 circles
Step-by-step explanation:
If you subract 3 squares from both sides, you end with 2 circles on the left and one square on the right. That is, 2 circles balance 1 square.
If you add 2 squares on the right, you need to add 2×2 = 4 circles on the left to balance them.
The answer is 5. 5×6 =30 30÷6 = 5
Answer: -1/9
Explanation: Perpendicular lines have <em>negative</em> reciprocal slopes.
A negative reciprocal slope is a fancy way of
saying flip the fraction and change the sign.
Notice that our slope is an integer.
We can turn it into a fraction by putting it over 1.
So we have 9/1.
A line perpendicular to this would be a negative reciprocal.
So flip the fraction, giving us 1/9, and change the sign to get -1/9.
