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)

Answer:

L= 10 in

W= 7 in

Step-by-step explanation:

Given data

let the widht be x

W= x

L= x+3

P=34 in

We know that

P=2L+2W

34= 2(x+3)+ 2(x)

34= 2x+6+2x

collect like terms

34= 4x+6

34-6= 4x

28= 4x

divide both sides by 4

x= 28/4

x=7

Put x= 7 in

L= x+3

L= 7+3= 10

Hence the width is 7in the length is 10 in
