Answer:
38, 39, and 40
Step-by-step explanation:
Let the three (3) consecutive integral numbers be:
n
n + 1
n + 2
Add the numbers together:
n + n + 1 + n + 2
Combine like terms:
n + n + n = 3n
1 + 2 = 3
Therefore:
3n + 3 = 117
Subtract 3 from each side of the equation.
3n + 3 - 3 = 117 - 3
Combine like terms:
3 - 3 = 0
117 - 3 = 114
3n = 114
Divide each side by 3
3n/3 = 114/3
n = 38
n + 1 = 38 + 1 = 39
n + 2 = 38 + 2 = 40
Check: 38 + 39 + 40 = 117
The three (3) consecutive integral numbers are:
38, 39, and 40.
Answer:
Y= 1.5x
Step-by-step explanation:
What you would do is divide all of the minutes by the amount of pages to find how long for each rate for one page. (ex. 18/12, Michael reads 1 page in 1.5 minutes. 12/8, Michael reads 1 page in 1.5 minutes. 30/20, Michael reads one page in 1.5 minutes) Therefore, yes it is proportional, and the equation is y=1.5x (there is no y intercept)
I hope this will help
Let Tritt's age = t & Jan's age = 2t - 3
if the sum of their ages equals 30 then..

combine terms and simplify

now simply divide

and to find Jan's age just plug 9 in


Jan's age = 15
Tritt's age = 9
Each of these equations follows the standard form: y = mx + b
The variable "m" is the slope, and the variable "b" is the y-intercept.
Therefore, with the equation y = 8/3x - 5, the slope ("m") would equal 8/3 and the y-intercept ("b") would equal -5
