15 less than the sum of k and 2

Answers

The algebraic expression for the given statement is k-13.

The given statement is "15 less than the sum of k and 2".

We need to form the algebraic expression for the given statement.

What is the algebraic expression?

In mathematics, an algebraic expression is an expression built up from integer constants, variables, and algebraic operations.

Now, the sum of k and 2=k+2

15 less than the sum of k and 2=(k+2)-15

=k+2-15

=k-13

Therefore, the algebraic expression for the given statement is k-13.

Liliana buys some softballs at $3 each and gloves at $20 each for her PE
class. She buys twice as many balls as gloves. She spends $138 in total,
which includes $8 tax: Which equation would you use to find the number of
gloves she buys?
Let x represent the number of gloves she buys.
A. 2 + 2x + 8 = 138
B. 20 (2x) + 3 (x) + 8 = 138
C. 20 (2) + 3 (2x) + 8 = 138
D. 20 (x) + 3(2x) = 138

Answers

Answer:

d. 20(x)+3(2x)=138

ap3x

The number of gloves she buys is B. 20 (2x) + 3 (x) + 8 = 138, where x = 3.

What are linear equation?

A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.

Now it is given that,

Cost of each softball , $3.

Cost of each gloves, $20 .

Total money spend , $138 .

Tax , $8 .

She buys twice as many softballs as gloves.

To Find the number of gloves she buys .

Let , x represent the number of gloves she buys.

So , number of softballs she buys is 2x .

20 (2x) + 3 (x) + 8 = 138

or, 40x + 3x + 8 = 138

or, 43x + 8 = 138

Subtract 8 both the side we get,

43x = 130

or, x = 3.02

0r, x = 3

Hence,the number of gloves she buys is B. 20 (2x) + 3 (x) + 8 = 138, where x = 3

what is the answer to this question im having trouble 3 x 2 - x?

Answers

Answer and Step-by-step explanation:

3 x 2 - x = ? Well, if you simplify it's just 5x. But, if you are trying to solve this then you have to know what x is or what your answer is. But, if you're trying to solve 3 x 2 = x then x would equal 6. Of course, if you know the answer or what x equals then plug it in as such, let's say x = 2 then you would plug 2 in for x and solve, 3 x 2 = 6 - 2 = 4. But, if you are trying to solve for x then look at the answer, let's say it is 24 so, 3 x 2 - x = 24, x would equal -18.

If c – a = b, which of the following statements is true?
A. a + b = c
B. c + b = a
C. a – c = b
D. b – c = a

Answers

The answer it’s d cuz it’s d

If c – a = b, then true statement is A. a + b = c

What is commutative property?

The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer.

Now the given statement is,

c – a = b

adding a to both the the side

c – a + a = b + a

⇒ c = b + a

Using commutative property of addition we get,

a + b = b + a

Therefore, we get

⇒ c = a + b

Thus the true statement is A. a + b = c

The Industrial Revolution began in GreatBritain, a fast development of society following the introduction of machines. The United States was slower than Great Britain tofully embrace the changes. Yet key technological developments caused a rapid growth in American urban areas.Better farming methods and tools in the 1800s increased food production. Americans were able to grow enough food for theirfamilies as well as to sell. The abundance caused food prices to fall.The expansion of cotton and the growth of textile factories in northern states helped produce the first wave of American industry,More people turned to work in northern factories as a way to support their families. Thousands of immigrants to the United Statesalso settled in or near port cities, looking for work. Even today, the need for work is a common reason people move to urban areas.As a result, cities grew in numbers of people and physical space. As more people and businesses moved in, they needed buildingsfor living and working. They needed ways to move around the city. We call this process urbanization.In 1820, the United States had only a few cities of 10,000 residents or more. About seven percent of U.S. residents lived in urbanareas. The number of cities with more than 10,000 people grew quickly over the next 40 years, especially in the Northeast andMidwest. By 1860, about 20 percent lived in cities. Philadelphia and New York City were the most populated cities in 1860 and wouldsoon reach one million residents.The urbanization of the United States quickened due to technology improvements. Without innovations in food production, thefactories could not have grown so quickly. The trend quickened after 1860 and continued throughout the 21st century as well.
