Two houses on the same side of the street have house numbers that are consecutive
DochEvi [55]

Answer: 28 and 30

Step-by-step explanation:

Let the house numbers on the street be represented by n and n+2 sine they are consecutive even integers. Therefore,

n + (n + 2) = 58

2n + 2 = 58

2n = 58 - 2

2n = 56

n = 56/2

n = 28

Therefore the second number will be:

= n + 2

= 28 + 2

= 30

The numbers are 28 and 30

How do u solve -8=C/-10

Isolate C, by multiplying both sides by -10, because the opposite of dividing by -10 is multiplying by it
so C=-8(-10)
