Answer:x =24
Step-by-step explanation: If we reverse that we will get x= 32x3/4 which is 24
Answer:
The year in which the population of Los Angeles reached 2.6 million is 1965.
Step-by-step explanation:
We are given the approximate population y (in millions) of Los Angeles between 1950 and 2000 is given by:
y = Population(in millions)
We are supposed to find the year in which the population of Los Angeles reached 2.6 million.
Substitute y = 2.6
The real solution is x=14.77≈15
We are given that 0 corresponds to 1950.
So, 15 corresponds to 1965
Hence the year in which the population of Los Angeles reached 2.6 million is 1965.
Answer:
Step-by-step explanation:
Let older brother age be x and the age difference between the brothers be y
Younger brother's current age = x - y
When older brother's age was at x - y, younger brother's age was x - 2y = 2
When young brother's age will be at x, older brother's age will be x + y = 20
Subtracting the first equation from the second: 3y = 18
y = 6
x = 14
So the older brother is 14 and the younger brother is 8.
Sum of three son's ages now = 15 + 11 + 7 = 33
Daddy's age now = 45
Age difference = 12
Each year, daddy's age goes up by 1 while the sum of three son's ages goes up by 3.
Dividing the age difference by the difference in age gain, 12 / (3 -1) = 12 / 2
= 6
So in 6 years when daddy is 51 and the sum of sons at 21, 17 and 13 will be equal.
Answer: the answer is -12. C
Step-by-step explanation:
2(x − 3) + 5x = 5(2x + 6) = -12
