Solve the following equation. Only enter the numeric answer (no variables). 30=2.5(10-2x)

Answers

Answer 1

Answer:

x = -1

Step-by-step explanation:

30 = 2.5(10)(-2x)  - you multiply by each

30 = 25 - 5x        - then pass 25 to the other side and subract

5x = - 5x               - then divide 5 / -5

x = -1                     - and you have the answer

Answer 2

Answer:

x= -1

Step-by-step explanation:

distribute 2.5 through the parenthese

30=25-5x

move variable to the left hand side an change its sign

5x+30 =25

move constant to the right hand side and change the sign

5x=25 -30

calculate the difference

5x= -5

divide both sides of the equation by 5

x= -1

Answer:

$0.12

Step-by-step explanation:

Set up and evaluate the optimization problems. (Enter your answers as comma-separated lists.) Find two positive integers such that their sum is 14, and the sum of their squares is minimized. Find two positive integers such that their sum is 14, and the sum of their squares is maximized.

Answers

Answer and Step-by-step explanation:

Let x and y be two positive integers and their sum is 14:

X + y = 14

And the sum of square of this number is:

f = x2 + y2

 = x2+ (14 – x)2

Differentiate with respect to x, we get:

F’(x) = [ x2 + (14 – x)2]’ = 0

        2x + 2(14-x)(-1) = 0

        2x +( 28 – 2x)(-1) = 0

     2x – 28 +2x = 0

        2x + 2x = 28

         4x = 28

       X = 7

Hence, y = 14 – x = 14 -7 = 7

Now taking second derivative test:

F”(x) > 0

For x = y = 7,f reaches its maximum value:

(7)2 + (7)2 = 49 + 49

                   = 98

F at endpoints x Є [ 0, 14]

F(0) = 02 + (14 – 0)2

       =  196

F(14) = (14)2 + (14 – 14)2

  = 196

Hence the sum of squares of these numbers is minimum when x = y = 7

And maximum when numbers are 0 and 14.

Answer:

I used the Interior Angles of a Triangle Rule --The sum of all 3 interior angles in a triangle is always 180°.

(3x + 28) + (5x - 18) + 90° = 180°

Now i can get rid of the parentheses and combine like terms.

3x + 5x + 28 - 18 + 90 = 180

8x + 10 + 90 = 180

8x + 100 = 180

Then i subtract 100 from both sides to isolate x.

8x + 100 - 100 = 180 - 100

8x = 80

Then, i divide both sides by 8 to find x.

8x ÷ 8 = 80 ÷ 8

x = 10

What's the length of side AB in ∆ABC shown?
A. 5
B. √313
C. 6
D. √15​

Answers

Answer:

The value of x = 5 units.

Step-by-step explanation:

Given the right-angled triangle ∆ABC with the following dimensions

AC = a = 12

BC = c = hypotenuse = 13

AB = b = x

Pythagorean Theorem

For a right-angled triangle with the sides, a and b the hypotenuse c is defined as:

[tex]c=\sqrt{a^2+b^2}[/tex]

Thus, using the Pythagorean Theorem to determine the value 'x',

[tex]b=\sqrt{c^2-a^2}[/tex]

as b = x, so

[tex]x=\sqrt{c^2-a^2}[/tex]

a = 12c = 13

so

[tex]x=\sqrt{13^2-12^2}[/tex]

[tex]x=5[/tex]

Therefore, the value of x = 5 units.

if 4 oranges make 1 cup of juice then how much will 6 oranges make

Answers

Answer:

1 and 1/2 cups

Step-by-step explanation:

4 oranges = 1 cup

6 oranges / 4 oranges in a cup = 1 1/2 cups

If 4 oranges make 1 cup of juice, then that means 1 orange makes 1/4 cup of juice.

So we know that each orange makes 1/4 cup of juice. We need to find how much juice 6 oranges will make. To do that, multiply 1/4 by 6.

1/4 times 6 equals 6/4 or 1 and 1/2.

6 oranges will make 1 and 1/2 cups of juice.
