Answer:

17

Step-by-step explanation:

These two angles add up to 180, so we can set up an equation. 5x-23+7x-1=180. Now we combine like variables, getting 12x-23-1=180. We add 23 to both sides, and get 12x-1=203. Then we add 1 to both sides, getting 12x=204. Finally we divide by 12 on both sides, with our result as x=17.

Zahra runs a 500-meter race at a constant speed. Which graph shows her distance from the finish line during the race?
makkiz [27]

Answer: The answer is the third figure. Attached the image.

Step-by-step explanation: Given that Zahra runs a 500-meter race at a constant speed. We are to select the correct graph from the four options that will show her distance from the finish line during the race.

We can see in graph 2, the distance covered by Zahra in metres increases at the same rate as the time increases in minutes.

But, since we are considering from the finish line, so option (#) will be right, because Zahra starts at 500 metres, decreases in the same manner as the increase of time and goes down to 0 on the positive X-axis.

Also,

Thus, the attached graph, which is the third option is the correct graph.

The sum of 5 consecutive even numbers is 216. What is the third number in the sequence
alexandr1967 [171]

Hello from MrBillDoesMath!

Answer:  NO solution possible!


Steps:

Let "n" be the first even number. We are told that


n + (n+2) + (n+4) + (n+6) + (n +8)  = 216


The third number, the value we want, is boldfaced above.


Simplify the above equation:

5n + ( 2 + 4 + 6 + 8 ) = 216   or


5n +  20  = 216  or

5n = 196


n = 196/5   is NOT an integer value.  This problem, as stated, has no solution.

Regards, MrB
