1) B=Bikers H=Hikers

H=B+178 (178 MORE HIKERS THAN BIKERS)

B+H=676 (TOTAL EQUATION)

COMBINE EQUATIONS (Plug in H from first equation into second one)
  B + B +178 = 676
SOLVE FOR B
2B=498
B=249 Total Bikers

Now for Hikers go back to the first equation we made

H= B+178.... Plug in B =249 and get

H=427

2) Children =C AND Adult =A

C+A=764  .............. C=764-A

2C+5A=2992

COMBINE EQUATIONS

2(764-A)+5A=2992

You can solve for A.
A=488

Now c GO BACK TO FIRST EQAUTION
C+A=764 and solve for C.

C=276

Find x in the given figure if m∠AOC = 124°.
Nastasia [14]

Answer:

A) 8

Step-by-step explanation:

Add angles AOB and BOC to get angle AOC.

Since we know the value of AOC is 124 and AOB+BOC=AO

Then (8x+25)+(6x-13)=124.

Combine like terms to get 14x+12= 124.

Solve for x by subtracting 12 from 124, then divide the answer by 14.

Can the following question be considered a statistical question and why or why not?
FinnZ [79.3K]

It could. If you turn it into an experiment. Let's say you take 100 students from each grade, and you ask them if they exercise. And then you wanna create a graph. And find out out of those students how many of them exercise and how many of them do not. Then turn it into a percent.

I hope this helps. If you have any further questions on this or any other questions just ask. I am here to help you, as needed.
