Answer:
Step-by-step explanation:
16 < 5x-6 < 29
add 6
22 < 5x < 35
divide by 5
4.4 < x < 7
Answer:
x = 5 is the right answer.
Step-by-step explanation:
As we know sum of all angles in a triangle is 180°.Therefore in this question we will form an equation.
Sum of all the angles of a triangle = 180
91 + 10x - 4 +8x +3 = 180
90 + 18x = 180
18x + 90 - 90 = 180 - 90
18x = 90
x = 90÷18 = 5
Therefore x = 5 is the right answer.
Answer: C.
Explanation: A function only has one y value for every x value. This means that an x cannot have more than one y value. You can do the vertical line test on graphs to figure out if it is a function or not. In this case, graph C is the only one that passes the vertical line test.
Answer:
4
Step-by-step explanation:
-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11.
These are the numbers -3, and 11, and every number in between them.
The number in the very middle of these numbers is 4.
Answer:
The speed of George the Pigeon in still air = 21 miles/hr
The speed of air = 3 miles/hr
Step-by-step explanation:
Let the speed of George the Pigeon in still air =
miles/hr
Let the speed of air =
miles/hr
Distance traveled = 72 miles
Relative speed against the wind =
miles/hr
Time taken against the wind = 4 hours
Relative speed with the wind =
miles/hr
Time taken against the wind = 3 hours
Using the formula:



Adding (1) and (2):

By equation (1):

Therefore, the answer is:
The speed of George the Pigeon in still air = 21 miles/hr
The speed of air = 3 miles/hr
