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.

A person invests $2,730 in an account that earns 4.2% annual interest. Find when the value of the investment reaches $5,000. If necessary, round to the nearest tenth.

Answers

Step-by-step explanation:

You want to calculate the interest on $2730 at 4.2% interest per year after 5,000 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:P is the principal amount, $2730.00.

r is the interest rate, 4.2% per year, or in decimal form, 4.2/100=0.042.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 2730 × 0.042 × 5 to get that:

The interest is: $573.30
