Answer:
8n + 5 = 69
And that number is 8, because 8•8+5=69
Step-by-step explanation:
"eight times a number and five is sixty-nine" in this statement the words "a number" is the number we dont know and so we use a variable for it. I put n, but you could have used x or a or any variable. The "and five" indicates adding. The "is" indicates equals.
(10x 5 - 3x 6)
(50x - 18x)
(f-g) = 32x
3t+9≥15 => 3t ≥ 6 => t ≥2 => t= [2,∞)

Correct question:
The LCM of two numbers is 9 times their HCF .The sum of LCM and HCF is 500 . Find the HCF of two numbers.
Answer:
The HCF of two numbers is 50.
Step-by-step explanation:
let the H.C.F of the two numbers = x
let the L.C.M of the two numbers = y
y = 9x -------equation (1)
y + x = 500 -------- equation (2)
y = 500 - x
Substitute in the value of y in equation (1)
500 - x = 9x
500 = 9x + x
500 = 10x
x = 500 / 10
x = 50
Therefore, the HCF of two numbers is 50.
