Find a difference equivalent to the product 11(x-y)


The equivalent expression for the given expression 11(x-y) is 11x - 11y.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is 11(x-y). The equivalent expression will be written as,

E = 11(x-y).

Multiply the number 11 in the whole equation and solve,

E = 11x - 11y

Therefore, the equivalent expression for the given expression 11(x-y) is 11x - 11y.

To know more about an expression follow

Just divide and multiply BUT when you divide or multiply by negative numbers you switch the symbol.

#1 is -18÷-3= 6; x is less than 6
#2 is 4×-2= -8; y is less than -8
#3 I don't understand the question
#4 -1.5×-2= 3; c is less than 3
#5 is 1/20×-5= -0.25; x is less than -0.25
#6 is not possible
#7 is 3÷-2=-1.5; b is greater than -1.5
#8 is -70÷-0.5= 35; a is greater than 35

Tbh I don't think any of these are right but I tried and it took me awhile so :/

Write each fraction as a percentage


Hi there!

To convert a fraction to a percentage you need to first convert the fraction to a decimal number. To convert a fraction to a decimal number you need to treat the fraction like a division problem.

(1)/(3) as a division problem would be 1 divided by 3, which is:

1 ÷ 3 = 0.3333333...

Now to covert a decimal to a percent all you do is move the decimal point over to the hundreds place, so it will look like this:


I will be rounded down because it is less then 5. Now just add a percent sign on the end and that is your answer! I should look like this:

Convert the mixed number to an improper fraction. 2 7/10 A.14/10 B.27/10 C.34/10 D.37/10


The value of the mixed number is A = 27/10

What are Mixed Numbers?

A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.

Given data ,

Let the mixed number be represented as A

Now , the equation will be

A = 2 7/10   be equation (1)

On converting the mixed number to an improper fraction , we get

Multiply the whole number by the denominator and add the numerator to it to get the new numerator of the improper fraction

So , A = [ ( 2 x 10 ) + 7 ] / 10

On simplifying the equation , we get

A = 27/10

Hence , the mixed number to improper fraction is A = 27/10

So, to make a mixed number into an improper fraction, you have to multiply the whole number by the denominator and then add the numerator o that number.

I hope this helps!

the population of the world is approximately 6200 million people. it is increasing by approximately 93 million people each year. use this information to calculate the percentage increase in the population over a year.


approximate population: 6,200 million
approximate increase: 93 million

Percentage increase:

93,000,000 / 6,200,000,000 = 0.015
0.015 x 100% = 1.5% increase
