Answer:

5

Step-by-step explanation:

According to the Order of Operations, in this case, just evaluate EVERYTHING in parentheses:

(14 + 3) - (2 × 6) = 5

17 - 12

Here are several acronyms you can use for the Order of Operations:

<u>GEMS[A]</u>

G - Grouping Symbols

E - Exponents

M - Multiplication & Division

S\A - Subtraction & Addition

<u>BOMDAS\BEMDAS</u>

B - Braces\Brackets

O\E - Order of Powers\Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

<u>PEMDAS</u>

P - Parentheses

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

There are many others, but I am pretty sure you will figure them out, or choose which one will work best for you.

I am joyous to assist you anytime.

Answer:

5

Step-by-step explanation:

This is a problem most likely relating to order of operations (i.e. PEMDAS) where the letters stand for the order you should solve the problem in.

P= Parenthesis

E= Exponent

M= Multiplication

D= Division

A= Addition

S= Subtraction

With this in mind, I solved (14+3) and (2x6), which gave me 17 and 12 respectively. After I subtracted 12 from 17 and got 5 as the answer

Find the smallest positive $n$ such that \begin{align*} n &amp;\equiv 3 \pmod{4}, \\ n &amp;\equiv 2 \pmod{5}, \\ n &amp;\equiv
Alex777 [14]

4, 5, and 7 are mutually coprime, so you can use the Chinese remainder theorem right away.

We construct a number x such that taking it mod 4, 5, and 7 leaves the desired remainders:

x=3\cdot5\cdot7+4\cdot2\cdot7+4\cdot5\cdot6

  • Taken mod 4, the last two terms vanish and we have

x\equiv3\cdot5\cdot7\equiv105\equiv1\pmod4

so we multiply the first term by 3.

  • Taken mod 5, the first and last terms vanish and we have

x\equiv4\cdot2\cdot7\equiv51\equiv1\pmod5

so we multiply the second term by 2.

  • Taken mod 7, the first two terms vanish and we have

x\equiv4\cdot5\cdot6\equiv120\equiv1\pmod7

so we multiply the last term by 7.

Now,

x=3^2\cdot5\cdot7+4\cdot2^2\cdot7+4\cdot5\cdot6^2=1147

By the CRT, the system of congruences has a general solution

n\equiv1147\pmod{4\cdot5\cdot7}\implies\boxed{n\equiv27\pmod{140}}

or all integers 27+140k, k\in\mathbb Z, the least (and positive) of which is 27.

1. A square ABCD has the vertices A(n, n), B(n, -n), C(-n, -n), and D(-n, n). Which vertex is in Quadrant III?
andrew-mc [135]

The four quadrants and the sign of coordinates is given as follows:

Quadrant I : (n, n ) both x and y positive.

Quadrant II : ( -n,n) = x negative and y positive.

Quadrant III : ( -n,-n) = both x and y negative.

Quadrant IV: (n, -n) = x positive and y negative.

So Based on the above concept , we can say that vertex C (-n,-n) has both x and y negative and so it lies in quadrant III.

Answer is Vertex C (-n,-n)

In a recent year, 22 percent of email users said they spend less time using email because of spam. what fraction of email users
Alchen [17]
Remember, percent is always out of 100. If you have 22%, you have 22 people per every 100 people, or, 22/100. 

22/100 is the incomplete answer because it needs to be simplified. If you divide both numbers by two you get 11/50 which is the lowest fraction you can have because 11 is a prime number.
