Answer:

x = 2

Step-by-step explanation:

12x - 4 = 4(2x + 1)

Distribution first

12x - 4 = 4(2x) + 4(1)

12x - 4 = 8x + 4

Isolate x to one side

12x - 4 - 8x = 8x - 8x + 4

12x - 8x - 4 = 4

4x - 4 = 4

4x - 4 + 4 = 4 + 4

4x = 8

4x/4 = 8/4

x = 2

Answer:

390

Step-by-step explanation:

5 or more, means round up.

So 385 ( 5 or above ) - round to the nearest tenths place...

= 390

Answer:

390

Step-by-step explanation:

The number in the tenth place is 80 so you look on the right, the number is 5. If the number is 5 or above, that means you go up. SO it's 390

Answer:

(2^2)3 = 2^6

(2^3)2 = 2^6

Step-by-step explanation:

There are various exponent rules. The problems that you were assigned must follow the power of a power rule:

(x^a)^b = x^a*b

Exponents must be multiplied according to this rule. Hope this helps.

Answer:p=-1 and q=1

Step-by-step explanation:

Answer:

p=3, q=5

Step-by-step explanation:

f(x) = x³-x²+px+q

factor: x+1 = 0   x = -1

(-1)³ - (-1)² + p*(-1) + q = 0

-2 - p + q = 0

p = q-2

(x-1) is factor of f(x) - 8, root x = 1 : f(x) = x³-x²+(q-2)x+q-8

(1)³ - (1)² + (q-2)(1) + q - 8 = 0

q - 2 + q - 8 = 0

2q = 10     q = 5

p = q-2 = 3

check: x³-x²+3x+5 = (x+1)(x²-2x+5)

x³-x²+3x+5 = (x²+3)(x-1) + 8

We want to see if the given statement is true. (which is, by definition).

We define two inverse matrixes A and B as two matrixes that when multiplied are equal to a matrix with only ones in the diagonal.

This matrix with only ones in the diagonal (and zeros every else) is called the identity matrix.

Then the statement:

"If matrix A and B are inverses of each other, then A times B=I,where I is the identity matrix"

Is true by definition of inverse matrixes.

The time it will a take them for both ricardo and his father to finish the painting if they work together is;

t = 2.4 hours

Time for ricardo to paint the set of kitchen cabinets = 6 hours

Time for Ricardo's father to finish painting = 4 hours

This means that ricardo in 1 hour paints 1/6 of the cabinets

His father in 1 hour paints 1/4 of the cabinets

If they work together, in one hour, they would have painted;

1/6 + 1/4 = 5/12 of the cabinet

then 12/12 will be done in; ((12/12) × 1)/(5/12)

⇒ 1 × 12/5

⇒ 2.4 hours

The correct answer is:  " 2 hours and 24 minutes ";

or; write as:  " 2.4 hours " .

____

Step-by-step explanation:

[tex]\frac{x}{4} + \frac{x}{6} = 1[/tex]  ;  → { " 1 (one) whole job." }.

       We want to solve for "x" ; the total time, in "hours", that will take them if they work together.
        What is the LCD (least common denominator of "4" and "6" ?
→  Note that "4 * 6 = 24" ;  so, "24" would work, but let's see if we can find the LCD —a number less then "24" ;

4:  2, 4,  12, 16, 20, 24,

6: 1, 2, 3, 6, 12

⇒  We see that "12" is the LCD.
_____
So, " [tex]\frac{x}{4} = \frac{?}{12}[/tex] " ;  to solve for "?" ;

 →  4 * (what value?) = 12 ?
   →   12 ÷ 4 = (that value) ; ⇒   =  " 3 " .
 _____
So:  [tex]\frac{x}{4} = \frac{(x*3)}{(4*3)} = \frac{3x}{12}[/tex] ;
_____
 Now:  " [tex]\frac{x}{6} = \frac{?}{12}[/tex] " ; to solve for "?" ;

→  6 * (what value?) = 12 ?
   →   12 ÷ 6 = (that value) ;  ⇒   =  " 2 " .

 _____

So:  " [tex]\frac{x}{6} = \frac{(x*2)}{(6*2)} = \frac{2x}{12}[/tex] ;

Now:  →  [tex]\frac{x}{4} + \frac{x}{6} = 1[/tex] ;

Substitute our converted values:
         →   [tex]\frac{3x}{12} + \frac{2x}{12}=1[/tex] ;

Then simplify the "left-hand side" of the equation:
_____
        →   [tex]\frac{3x}{12} + \frac{2x}{12} = \frac{(3x+2x)}{12}[/tex]  = [tex]\frac{5x}{12}[/tex]  ;

Now, rewrite the simplified equation; and bring down the "1" :
_____

        →   [tex]\frac{5x}{12} = 1[/tex]   ;

Now, solve for "x" ; as follows:
_____
 ⇒   5x  =  ( 1 * 12 )  ;

  →   5x  =  12  ;

Now, divide Each Side of the equation by "5" ;

to isolate "x" on one side of the equation; & to solve for "x" (in hours):
 _____
  →   5x / 5  =  12 / 5  ;

_____
to get:   x =  (12/5) hours.
_____
Now:  We have (12/5) of 1 hour ;     24/10

Note the exact conversion:  " 60 min. = 1 hr." :

So, 12/5 of 60 minutes;

=  " [tex]\frac{12}{5}[/tex] * [tex]}\frac{60}{1}[/tex] "  (minutes) ;
____
The "5" cancels to a "1" ;  and the "60" cancels to a "12" :

  {since:  "60 ÷ 5 = 12" ;  & since:  "5 ÷ 5 = 1 " .}.

→ And we can rewrite as:
    " [tex]\frac{12}{1} * \frac{12}{1}[/tex] "  (minutes) =  "12 * 12" minutes =  144 minutes.
⇒  " 144 minutes" equals:  How many hours?  " 144 ÷ 60  =  2.4  hours " ;

or; more specifically:

⇒ We have "2 hours and _(some) minutes".

→ that is;  " 2 hours plus 0.4 hour(s) " .

⇒  [tex]\frac{(0.4) hr}{1}*\frac{(60)min}{1 hr} = [(0.4)*(60)] minutes[/tex] ;

                              =  24 minutes.

____

Alternate method:
____
(12/5 hours) = (12 ÷ 5) hours =   " 2.4 hours " ;  (and continue if desired).
____

So:  The correct answer is:  " 2 hours and 24 minutes ";

                                       or; write as:  " 2.4 hours " .

Answer:

20cm

Step-by-step explanation:

1. First find the area of the triangle

a = 1/2 × base × h

a = 1/2 × 10 × 11

a = 55cm²

2. Then times the area of the triangle by 8 to find the area of the rectangle

55 × 8 = 440cm²

3. Find the width of the rectangle:

The area of a rectangle is = l × w

22 × width = 440cm²

width = 440 ÷ 22

width = 20cm

Answer: Width = 20

Step-by-step explanation:

Give the area of triangle = x

So the area of rectangle = 8x

the area of triangle = (11 × 10) ÷ 2 = 55

So the area of rectangle = 8(55) = 440

The area of rectangle = W × L

So 440 = W × 22

W = 20
