The sum of two numbers is 27. One number is seven less than the other. Find the numbers
Marat540 [252]

Answer:

17 and 10

Step-by-step explanation:

Write the problem as an equation.

a+b=27

a=b-7

Where a and b are the two numbers you are trying to find. You could use any variables. Then solve.

b+(b-7)=27      Sub (b-7) for a

2b-7=27          Group like terms

2b=34             Add 7 to both sides

b=17                 Divide both sides by 2.

Because b=17, a must be 10.

riangle A″B″C″ is formed using the translation (x + 0, y + 2) and the dilation by a scale factor of 2 from the origin. Which equ
Shtirlitz [24]

The relationship between segment AC and segment A double prime C double prime is AC = A''C'' /2.

<h3>What is a Scale Factor ?</h3>

The ratio by which the new image is bigger or smaller than the original image is the scale factor.

It is given that

Triangle A″B″C″ is formed using the translation (x + 0, y + 2)

and the dilation by a scale factor of 2 from the origin.

coordinate plane with triangle ABC at A (- 3,  3), B (1, - 3), and C (- 3, -3).

segment AC is equal to A''C'' over 2

Scale factor = 2

The coordinates are

A (- 3,  3), B (1, - 3), and c (- 3, -3) is translated using  (x + 2, y + 0),

new coordinates

A'(- 1,  3), B'(3, - 3), and C'(- 1, -3).

The dilation by a scale factor of from the origin

A″ (-2, 6), B″ (6, -6) and C″(-2, -6)

By the distance formula

AB = \rm \sqrt {52}

A''B'' = \rm \sqrt{ 8^2 + 12^2}\\ = 2 \rm \sqrt {52}

Therefore

AB = A''B'' /2

Similarly AC = A''C'' /2

The relationship between segment AC and segment A double prime C double prime is AC = A''C'' /2.
