The sum of a number and three more than twice that number is 27 . what is the smaller number

write a formula

27=x +(2x+3)

2x+x = 3x

27 = 3x+3

24=3x

x=8

double check 8+(8*2+3) = 27

Hence, the smaller number is:

                     8

Let the number be x.

This means that twice the number is represented as: 2x

Now three more than twice the number x is represented by: 2x+3

It is given that:

The sum of a number and three more than twice that number is 27 .

This means that:

Now on subtracting both side by 3 we get:

on dividing both side by 3 we get the value of x as:

       The smaller number is: 8

answer: 1 + 1 = 11

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
