Answer:
8x-55818-t
Step-by-step explanation:
The figure has 5 sides, so it must be a pentagon. Pentagon’s interior angles sum up to 540°.
Therefore:
132+90+3x=540
222+3x=540
3x=318
x=106
Checking work, where x=106
222+3(106)=540.
So x°=106°
We want to put b alone on one side of the equation.
If we multiply by 1/2, we get 1/4bh = A/2. Not only did we not remove a variable from the left side, we made it even more complicated.
So the answer is A.
The units of the initial and final rates of speed are;
<u><em>Initial rate of Speed = ft/hr</em></u>
<u><em>Final rate of speed = mi/min</em></u>
- We are told that the conversion factors he used are;
5280 ft/1 mi and 1 hr/60 min
- Now, the meaning of 5280 ft/1 mi denotes that;
5280 ft mile is equivalent to 1 mile
This means that the initial distance <em>unit </em>used was ft while the final one was mile
Also, 1 hr/60 min denotes that;
1 hour is equivalent to 60 minutes.
This means that the initial time units used was hour while the final one was minute.
- In conclusion, since we know the initial time and distance units used, we can say that the initial rate of speed ft/hr while final speed rate was miles/minutes.

Answer:
Adult tickets sold: 156
Step-by-step explanation:
Adult ticket: x
Student ticket: y
x + y = 260 ===> -6(x + y = 260) ===> -6x -6y = -1560
6x + 4.5y = 1404 ===> 6x + 4.5y = 1404
________________
add the two equations to eliminate a variable: -1.5y = -156
divide by -1.5: y = 104
substitution to find x:
x + y = 260
x + 104 = 260
x = 156
