The sum of 2 consecutive numbers is 69. What are the numbers?
Vaselesa [24]

Answer:

<h3>            34, 35</h3>

Step-by-step explanation:

z - some integer

then the consecutive integer would be:

z+1,  (or z-1)

the sum is 69 so:

z + z+1 = 96

2z = 68

z = 34

z+1 = 34 + 1 = 35

(or:

z + z-1 = 69

2z = 70

z = 35

z-1 = 35 - 1 = 34)

Solve for b.
andriy [413]
It's -18.

-1/6b=3

Multiply the reciprocal of -1/6 to both sides, this will get x by itself

(-6/1)*-1/6b=3*(-6/1)

b= -18/1
b= -18
