Answer 1

Answer:

We know that:

PQ = p - q

Also:

PA = p - a

We are given:

PA = 1/6PQ ⇒ PQ = 6 PA

Compare the values of PQ

p - q = 6(p - a)p - q = 6p - 6a6a = 6p - p + q6a = 5p + qa = 1/6(5p + q)

Find RS 2x+15 3x+5 6x-37

Answers

Answer:2x+15+6x-37/2=3x+5

We move all terms to the left:

2x+15+6x-37/2-(3x+5)=0

We add all the numbers together, and all the variables

8x-(3x+5)+15-37/2=0

We get rid of parentheses

8x-3x-5+15-37/2=0

We multiply all the terms by the denominator

8x*2-3x*2-37-5*2+15*2=0

We add all the numbers together, and all the variables

8x*2-3x*2-17=0

Wy multiply elements

16x-6x-17=0

We add all the numbers together, and all the variables

10x-17=0

We move all terms containing x to the left, all other terms to the right

10x=17

x=17/10

x=1+7/10

The value of RS is 31.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If RS and UT are parallel, then their corresponding sides are proportional. Thus,

RS/UT = (2x + 15)/(6x - 37)

Now,

RS/UT = (2x + 15)/(6x - 37)

Cross-multiplying.

(2x + 15)UT = RS(6x - 37)

Expanding and simplifying.

2xUT + 15UT = 6xRS - 37RS

Rearranging.

6xRS - 2xUT = 15UT + 37RS

Factorizing.

2x(3RS - UT) = 15UT + 37RS

Dividing both sides by (3RS - UT):

2x = (15UT + 37RS)/(3RS - UT)

Substituting RS = 2x + 15 and UT = 6x - 37:

2x = (15(6x - 37) + 37(2x + 15))/(3(2x + 15) - (6x - 37))

Simplifying

2x = (90x - 555 + 74x + 555)/(6x + 36)

2x = (164x)/(6x + 36)

Multiplying both sides by (6x + 36):

12x² + 72x = 164x

Simplifying

12x² - 92x = 0

Factoring out 4x.

4x(3x - 23) = 0

So,

x = 0 or x = 23/3.

Since x cannot be 0 (as it would make UT = -37, (which is not possible),

x = 23/3.

Substituting this value of x into RS = 2x + 15.

RS = 2(23/3) + 15 = 31

Thus,

The value of RS is 31.
