Answer: OPTION 3. -7
Step-by-step explanation:
Given
-52=-4x-5(-2x+2)
Distributive property (REMEMBER you need to change signs)
-52=-4x-5×(-2x)-5×2
-52=-4x+10x-10
Combine like terms (-4x and 10x)
-52=6x-10
Add 10 on both sides
-52+10=6x-10+10
-42=6x
Divide 6 on both sides
-42/6=6/6x
x=-7
Hope this helps!! :)
Please let me know if you have any question
Hey there! :D
Plug in x for 2.
4x= 4(2)
x^4= (2^4)
Evaluate.
4x= 8 2^4= 16
Now, subtract the difference.
16-8= 4
The difference is 4.
I hope this helps!

Answer:
2:1
Step-by-step explanation:
average age of both = 40
average age of teachers = 35
average age of professors = 50
35 + 35 + 50 = 120
120 / 3 = 40
The answer x = 11 is correct for problem 4. Nice work.
Use this x value to find the answer in problem 5. From problem 4, we're told that Romeo runs at a speed of 5 m/s. If he runs for x = 11 seconds,then he runs a total distance of:
5*x =(5 m/s)*(x meters) = (5 m/s)*(11 seconds) = 5*11 = 55 meters
The answer to problem five is 55 meters
