the product of a number and three increased by four is the same as fourteen less than the product of twelve and a number

50 points, PLS ANSWER ASAP

Answers

Answer 1

Answer:

Let the number be x.

[tex]3*x+4=12*x-14[/tex]

[tex]3x+4=12x-14[/tex]

Subtract 4 from both sides:

[tex]3x+4-4=12x-14-4[/tex]

[tex]3x=12x-18[/tex]

Subtract 12x from both sides:

[tex]3x-12x=12x-18-12x[/tex]

[tex]-9x=-18[/tex]

Divide both sides by -9:

[tex]\frac{-9x}{-9} =\frac{-18}{-9}[/tex]

[tex]x=2[/tex]

The number is 2.

Answer 2

The Number is 2

What is Number?

A Number is an arithmetic value used for representing the quantity and used in making calculations.

Given that the product of a number and 3 is equal to the 14 less than product of twelve and that number.

Let the number be x

3x + 4 = 12x - 14

12x - 3x = 14 + 4

9x = 18

x = 2

Hence, the required number is 2.

Kevin is creating a target for a game that will be played at the school's carnival and needs to put red tape in the shape of an "x" as shown below. If the area of the square board is 25 square feet, how many feet of tape will he need?

Answers

Answer:Kevin need 14.14 feet of red tape  

Step-by-step explanation:

Given: (Figure Attached)

Area of Square  = 25 square feet

As we know

Area of square = length x width = a x a = 25

a * a = 25

a =  ±5 by taking square root both sides

It means a = 5 as the length can not be negative

Now we know the length of sides of square and as shown in figure we can break the figure in two triangles,

By using Pythagoras theorem on one triangle we will find the length of one line of x and then multiply the x with 2 to get the overall feet of tape.

 =  

=  

x = ± 7.07 It means x = 7.07

Now the total tape required is 2 * x = 2*7.07 = 14.14

2) Given any two (x, y) points on the line: Slope or "m" = y2 - y1 / x2 - x1

The given decimal is 5.437

Now, the expanded form is

5+4/10+3/100+7/1000

= 5+0.4+0.03+0.007

Therefore, the expanded form of the decimal 5.437 is 5+0.4+0.03+0.007.

Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% disount.

Now,

Since, Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% discount.

Hence, The discount price = 35% of $347.25

                                          = 35/100 × $347.25

Answer:

f(2) = -3

Step-by-step explanation:

Given the graph of a negative-sloped function:

In order to determine the value of a function given that x = 2, simply locate the x-coordinate of 2 in the graph, and find its corresponding y-coodinate. Doing so will provide you the corresponding output value of y = -3. Therefore, the value of the function at x = 2 is f(x) = -3, or f(2) = -3.
