Answer:

Equations:

  • A number decreased by three is seven.
  • The quotient of a number and six is two.
  • x – 5 = 21

Expressions:

  • 9 + n
  • The product of a number and eleven

Step-by-step explanation:

Required

Determine which is an expression and which is an equation

To start with, we analyse each of the options one after the other

<em></em>

(a): A number decreased by three is seven.

Let the number be n

<em></em>

<em>So, when n is increased by 3, the result  is 7. </em>

This statement can be represented as:

<em></em>n + 3 = 7<em></em>

<em></em>

<em>The above is an equation because it has an = sign</em>

(b) 9 + n

This is not an equation <em>because it has no = sign.</em>

<em>Hence, it is an expression.</em>

(c) The product of a number and eleven

Let the number be n

<em></em>

<em>n multiplied by 11 is represented as:</em>

<em></em>n * 11<em></em>

<em></em>

This is not an equation <em>because it has no = sign.</em>

<em>Hence, it is an expression.</em>

(d) The quotient of a number and six is two.

Let the number be n

<em></em>

<em>So, the quotient of n and 6, is 2. </em>

This statement can be represented as:

\frac{n}{6} = 2

<em></em>

<em>The above is an equation because it has an = sign</em>

(e) x – 5 = 21

<em>The above is an equation because it has an = sign</em>

Suppose you were deciding on a ticket price for a fundraiser dinner. There may be a temptation to continue to raise the ticket s
cestrela7 [59]

Answer:

$50 per ticket.

Step-by-step explanation:

Although it is tempting to keep raising the price for a higher profit, if you raise the price by too much, people will stop buying tickets and you will not gain as much money as you could have gotten with, say, $50 per plate.

The more you raise the price, the less tickets you can sell.

Hope this helps!

Solve the equation for all real solutions in simplest form.<br> 3x2 - 12x + 11 = x
Ivanshal [37]

Answer:

(13 + or - (sign) square root(37)) / 6

Step-by-step explanation:

First search up the quadratic formula which is

x = (- b + or - square root(b^2 - 4ac)) / 2a

and to find a, b, and c you need this formula

ax^2 + bx + c = 0 (btw this is the safest solution to finding your answer with a number in-front of a quadratic equation.)

Math:

a = 3, b = -13, c = 11

b = -13, because of the x on the other end of the equation as the equation above "ax^2 + bx + c = 0" you need the zero to proceed to this next step.

Side Note: You only take the number and not the variable, variables are x, y, w, z, or etc.

(- (- 13) + or - square root((-13)^2 - 4(3)(11) ) ) / 2 * 3

13 + or - square root(37) / 6

Based on the data set shown, which of the following is a true statement?
patriot [66]
The mean, median, and mode are equal to 1. So among the choices, the first one is correct - mean = mode

Mean - an <em>average </em>of the given set of number; to find this, add the numbers and divide it by 11 (the number of given data)
   = (-1 + -1 + 0 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3) / 11
   = 1

Median - the <em>middle or center</em> of the given set; to find this, arrange the numbers in numerical order, then get the center or middle number as the median
   = <span>-1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
   = [</span><span>-1, -1, 0, 1, 1,] <u>1</u>, [1, 2, 2, 2, 3]

Mode - is the value that occurs most of the time in the given set; so obviously <em>number 1 occurred four times</em> so 1 is our mode
