What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be = A

Now , the value of equation A is

4x - 5 = -6x + 15 be equation (1)

Now , on simplifying the equation , we get

4x - 5 = -6x + 15

Adding 6x on both sides of the equation ,we get

10x - 5 = 15

Adding 5 on both sides of the equation , we get

10x = 20

Divide by 2 on both sides of the equation, we get

x = 20/10

x = 2

Therefore , the value of x is 2

Hence , The value of x in the equation 4x - 5 = -6x + 15 is x = 2

Find the product of 543.1187 and 100 A. 5.431187 B. 54,311.87 C. 5,431.187 D. 54.31187 Can someone also explain how they came up with the answer so that I can understand? (do you move the decimal? If so, to the left or right? How many times you move it?

Answers

$543.1187*100=\boxed{54311.87}$

When you're multiplying by a power of 10 such as 100, the decimal point moves two places to the right. Note that this corresponds with the number of zeroes in 100. Of course our number is going to get bigger, not smaller, which means we'd have to be going right. If we multiplied by something like 0.001, we'd also be going two places, just going smaller and to the left.

The answer would be 543.1187 X 100= {54311.87}

A wheel has a diameter of x inches and a second wheel has a diameter of y inches. The first wheel covers a distance of d feet in 100 revolutions. How many revolutions does the second wheel make in covering d feet?

Answers

You'd want an expression which relates to x, y and d.
The distance d is x times pi times 100. One divides back by pi and by y to get the # of revolutions (that 100 :)) ) and so one gets $(100x)/(y)$ as the number of revolutions.
