The sun of three consecutive integers is 60 find the integers

prohojiy [21]

Answer:

let the three consecutive Integers be

x , x+1 , x+2

their sum is 60,

so,

x + x + 1 + x + 2 = 60

→ 3x + 3 = 60

→ 3x = 60 - 3 = 57

→ x = 57/3 = 19

therefore, 1st integer = 19

2nd integer = x + 1 = 19 + 1 = 20

3rd integer = x + 2 = 19 + 2 = 21

so,

the three consecutive Integers are 19 , 20 and 21.

hope this answer helps you dear... take care and may u have a great day ahead!

Answer:

-7/6

Step-by-step explanation:

The slope formula can be used with any pair of points.

m = (y2 -y1)/(x2 -x1)

m = (1 -8)/(-2 -(-8)) = -7/6
