Answer: X= 4/3 I hope this helps:)
Step-by-step explanation:
(3x ). • 4= 16
divide by 4
3x = 4
divide by 3
x= 4/3
Answer:
The correct option is C.
Step-by-step explanation:
The time in first figure is 3:00 pm and the time in second figure is 4:30 pm.
So total time taken by car is

It means total time taken by car is 1.5 hour.
The distance in first figure is 50 miles and the speed in second figure is 155 miles.
So total distance travelled by car is

It means total distance travelled by car is 105 miles.
The formula of speed is


Therefore option B represents the solution. Option B is incorrect.
Multiply both sides by 1.5 hours.

Therefore option D represents the solution. Option D is incorrect.
Divide both sides by speed.

Therefore option A represents the solution. Option A is incorrect.
Option C can not represent the solution, therefore option C is correct.
Answer: x = 40
Step-by-step explanation:
these two angles are vertical angles, they will equal each other
therefore, move numbers and variables to the opposite sides of the = sign to isolate the X
3x-10 = 2x + 30
+10 +10 move the -10 by doing opposite
_____________
3x = 2x + 40
-2x -2x move -2x by doing opposite
____________
x = 40
you can check your work by substituting 40 in place of x
3(40) - 10 = 2(40) +30
120-10 = 80 + 30
110 = 110
answer is correct
Answer:

Step-by-step explanation:
Fixed monthly fee = $20
Amount charged per minute for long distance calls = $0.20
denotes total cost such that
minutes are used for long distance calls.
Amount charged for
minutes for long distance calls 
Therefore, an equation for the total cost, C, when N minutes are used for long distance calls is 
5a^10-2 I’m pretty sure that’s the right answer
