The sum of five consecutive integers equals 5.5 times the middle integer. Find the integers.
kogti [31]

The five consecutive integers are -2, -1, 0, 1 and 2.

<h3>What are the values of the integers?</h3>

Given that;

The sum of five consecutive integers equals 5.5 times the middle integer.

Since the integers are consecutive, let the integer be;

x, x+1, x+2, x+3 and x+4.

Now, sum of the integers equals 5.5 times the middle integer.

Middle integer is x+2.

Hence we have;

x + x+1 + x+2 + x+3 + x+4 = 5.5( x+2 )

x + x+1 + x+2 + x+3 + x+4 = 5.5x + 11

We collect like terms

x + x + x + x + x - 5.5x = 11 - 1 - 2 - 3 - 4

5x - 5.5x = 1

-0.5x = 1

x = -( 1 / 0.5 )

x = -2

Since our integers are; x, x+1, x+2, x+3 and x+4.

We substitute in the value of x

x = -2

x+1 = -2 + 1 = -1

x+2 = -2 + 2 = 0

x+3 = -2 + 3 = 1

x+4 = -2 + 4 = 2

Therefore, the five consecutive integers are -2, -1, 0, 1 and 2.

Find the values of a and b that complete the mapping diagram.
Rufina [12.5K]

Value of a and b that completes the mapping diagram will be a=0 and b=1

• Mapping diagram simply means a function that has a special type of relation where the elements of the domain are paired with that of the range.

• Mapping diagram consists of two parallel columns, the first column depicts the domain of the function whereas the second column depicts the range.

• Lines are drawn from first column to second column i.e. from domain to range, to represent the relation between 2 elements.

• Mapping is quite similar to making a flowchart, showing input and output values.

• Point to be noted that every mapping is a relation but every relation is not a mapping.

Value of a and b that completes the mapping diagram will be a=0 and b=1
