**PLEASE HELP** Juan is three times as old as Gabe and Gabe is six years older than Catherine. If the sum of their ages is 149, how old is each person?

Above,please mark as brainliest

Step-by-step explanation:

Catherine:x

Gabe:x+6

Juan:3(x+6)=3x+18

(3x+18)+(x+6)+x=149

5x+24=149

5x=125

x=25

Catherine:25

Gabe:31

Juan:93

Check:93+25+31=149

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

you divide them and then you get the answer i took this class this year
