:) /

Step-by-step explanation:,,

Answer:

The answer is B:subtract 1,add x,divide by 4

The other answer is D:add x,subtract 1,divide 4

Step-by-step explanation:

when you subtract 1 you isolate 3x so the equation looks like 3x=-x+3

the next step is to add x to both sides so you isolate the x to one side after doing that your equation should look like 4x=3,after this you divide both sides to the solution x=(3)/(4)

The answer is also D because if you add x to both sides u isolate x to the left side so the equation will look like 1+4x=4 the next step will be to subtract one from each side and after doing this the equation should look like 4x=3 which should look familiar because its the same exact solution as B was so the answer to this choice is x=(3)/(4)

With that evidence I can reasonably say that answer to the question is B,and D

Za and Z6
are
complementary angles. Za measures 78°.
What is the measure of Zb?

Answers

Answer:

\boxed{\angle b = 12 \degree}

Given:

\angle a \: and \: \angle b \: are \: complementary \: angles\n \n \angle a = 78 \degree

Step-by-step explanation:

Two Angles are Complementary when they add up to 90° (a Right Angle).

=  > \angle a + \angle b = 90 \degree \n  \n  =  >  78 \degree +  \angle b = 90\degree \n  \n  =  > \angle b = 90 \degree - 78 \degree \n  \n  =  >  \angle b = 12 \degree

Mr. Johnson leaves on a trip planning to travel 24 mph. How fast must his son James travel to overtake him in 5 hours if he starts 2 1 2 hours after his father?

Answers

The distance traveled by Mr.Johnson in 1 hour = 24 miles
Time after which his son James starts the chase = 2 1/2 hours
                                                                                 = 5/2 hours
                                                                                 = 2.5 hours
Then
time after which James will catch Mr.Johnson = 5 + 2.5 hours
                                                                          = 7.5 hours
Distance traveled by Mr.Johnson in 7.5 hours = 24 * 7.5 miles
                                                                         = 180 miles
So the distance James need to cover is 180 miles and that has to be covered in 5 hours
So
Speed at which James needs to travel = 180/5 miles per hour
                                                               = 36 miles per hour
From the above deduction we can conclude that James needs to travel at a speed of 36 miles per hour to catch his fathe in 5 hours.
                  

Final answer:

To overtake his father in 5 hours, who started 2.5 hours earlier, James will need to travel at an average speed of 36 mph.

Explanation:

This is a relative speed problem in physics. The father departs first and travels for a total of 7.5 (5+2.5) hours at a speed of 24 mph. Therefore, Mr. Johnson travels a total distance of 180 (24 * 7.5) miles. James leaves 2 1/2 hours after his father and needs to cover the same distance in 5 hours to overtake him. Therefore, by dividing the total distance (180 miles) by the time (5 hours), we find that James needs to travel at 36 mph to overtake his father.
