Decimal numbers are numbers that have fractional parts.

Take for instance the following products.

Assume the power of 10 is n.

• Notice that, when the n is positive, the decimal place moves forward n times.
• Similarly, when n is negative, the decimal place moves backward n times.

So, patterns can be used to calculate the product of a decimal and a power of 10 by moving the decimal place forward or backward

Answer:

When we multiply a decimal by a number with power of 10, the decimal point moves to the right by the same number of zeros in the power of ten multiplier.

For example:

Multiplying 7.362 by 100.

As there are 2 zeroes in 100, we will move the decimal to 2 places in the right.

Hence,

Powers of 10 are like 10,100,1000 and so on.

Answer:

-128x+33=0

Step-by-step explanation:

Given the expression −4(32x−12)=−15

Step one : let's open up the bracket

We have

-128x+48=15

-128x+48-15=0

-128x+33=0

The cost of the bench for the condition is 4350.

What are Mathematical operators?

A collection of numbers and operations is an expression in mathematics. The following are the parts of a math expression that do a math operation:

Operands: Operands are the numbers that an operator uses. The terms that are given to the operands vary according to the kind of operation.

Given the total cost of the bench and table = $655

The garden table cost $45 less than the bench,

let the cost of the bench be x

cost of table is x - 45

according to the conditions,

x  + x - 45 = 655

2x = 655 + 45

x = 722/2

x = $350

Hence the cost of the bench is $350.

Answer:

$444

Step-by-step explanation:

let the cost of the bench = x

the cost of the garden table is x + 94

 so,

x + (x + 94) = 794

2x + 94 = 794

2x = 700

x = 350

The bench costs $350 and the garden table costs 350 + 94 = $444
