Answer:
So the age of Mr.Jones = 39 yrs. |
the age of his wife = 39-4 = 35 yrs.|
and the age his son = 39-31 = 8 yrs.|
Step-by-step explanation:
Let the age of Mr.Jones = x
So, the age of his wife = x-4 (wife is younger by 4 years)
and the age of his son = x-31 (son is younger by 31 years)
Sum of their ages = x + (x-4) + (x-31) = 82
= x + x - 4 + x - 31 = 82 (By removing the brackets)
= 3x - 35 = 82
= 3x = 117 (By adding 35 both the sides)
= x = = 39
Answer:
3
Step-by-step explanation:
For this question, you need to make change the denominators of the fractions to be equal, making them the same lowest common denominator.
8/9 -> 40/45
4/15 -> 12/45
Since 12 goes into 40 3 1/3 times, he can patrol that many neighborhoods in 8/9's of an hour, which is rounded to 3 because he doesn't have enough time for 4.
Answer:
0 = -54
Step-by-step explanation:
4(3x + 8) − 9 = 2(6x − 8) − 15
12x + 32 - 9 = 12x - 16 - 15
12x + 23 = 12x - 31
12x = 12x - 54
0 = -54
No solutions.
Best of Luck!
It´s length is 10.5 because:
Perimeter = (2 x width) + (2 x length), so the equation is:
Length = [Perimeter - (2 x width)] / 2
Answer:
32% of 13 is 3.84
Step-by-step explanation:
but if your doing estimate one of those it would be 1/3*12
hope that helped
