Answer:

Jenny´s age is 19 and her mother is 43.

Step-by-step explanation:

1. Plug in the first value of the set:

x=12

x+2x+5=62

12+2*12+5=62

12+24+5=62

41=62

41 is different from 62, so Jenny isn´t 12 years old.

2. Plug in the second value of the set:

x=15

x+2x+5=62

15+2*15+5=62

15+30+5=62

50=62

50 is different from 62, so Jenny isn´t 15 years old.

3. Plug in the third value of the set:

x=18

x+2x+5=62

18+2*18+5=62

18+36+5=62

=59

59 is different from 62, so Jenny isn´t 18 years old.

4. Plug in the fourth value of the set:

x=19

x+2x+5=62

19+2*19+5=62

19+38+5=62

62=62

Therefore Jenny´s 19 years old.

5. Calculate Jenny´s mother age:

As the sum of their ages is 62 ages, we have the following equation:

x+y=62

where

x=Jenny´s age

y=Jenny´s mother age

Replacing the Jenny´s age we have:

19+y=62

Solving for y:

y=62-19

y=43

Therefore Jenny's mother age is 43 years old.

X + 2x + 5 = 62 which can be turned into.
3x + 5 = 62 
      -5      -5 now we subtract 5 from each side
3x = 57
/3     /3 now we divide 3 from each side to get...
x = 19.
Now to check 19 + (2 x 19) + 5 does in fact equal 62.  Jenny is 19 years old.  Hope this helped.

Sever21 [200]

Answer: See explanation

Step-by-step explanation:

From the equation, we are informed that Mr. Robison rides 136 miles per hour on his bike ride and that he wants to ride more than 360 miles at the same rate during his next bike ride.

The inequality that represents all possible values for b, the number of hours Mr. Robison must bike will be:

136b > 360

b > 360/136

b > 2.65

Therefore, Me Robinson must bike for more than 2.65 hours
