Step-by-step explanation:

(1)

1 x = 12

3

multiply both sides by the 3

3 × 1 x = 12 × 3

3

x = 36

(2)

3x + 3 = 21

( group like terms)

3x = 21 - 3

3x = 18

( divide both sides by 3)

3x = 18

3 3

x = 6

(3)

9.95 + 0.30( 35 )

=9.95 + 10.5

=20.45

(4)

(4)

(I'm not soo sure about this one)

equation = 6x + 27 = x

11

solution

( multiply both sides by 11)

= (6x + 27) ×11 = x × 11

11

= 6x + 27 = 11x

( grouping like term)

27 = 11x - 6x

27 = 5x

(divide both sides by 5)

27 = 5x

5 5

x = 5.4

the number of shirt they can buy is 5 or 5.4

Answer:

Step-by-step explanation:

In each case, draw the right triangle which produces the inverse trig value. That is, label the two sides as needed, and calculate the third side.

It should be clear that

tan(sin^{-1} x/4) = x/\sqrt{16-x^{2} }

sin(tan^{-1} x/4) = x/\sqrt{16+x^{2} }

sin(2α) = 2 sinα cosα

So,

1/2 sin(2sin^{-1} x/4) = (1/2)(x/4) * x/\sqrt{16-x^2} = x^{2} /(8\sqrt{16-x^2})

See what you can do with the others.

Answer:

x = 7

Step-by-step explanation:

\frac{3}{7} x + 5 = 8

\frac{3}{7} x = 8-5

\frac{3}{7}  x = 3

x = 3 / \frac{3}{7}

x = 3 * \frac{7}{3} cancel 3

Then

x = 7

Wendy keeps her hamster, Fluffy, in a cage shaped like a rectangular prism that is 20 inches long, 14 inches wide, and has a vol
Alex17521 [72]

Speedy cage is 2 inches taller than fluffy cage.

<h3>How to find the volume of a rectangular prism?</h3>

The volume of rectangular prism = lwh

where

  • l =length
  • h = height
  • w = weight

Therefore,

height of fluffy cage can be calculate as follows:

4340 = 20 × 14 × h

4340 = 280h

h = 4340 / 280

h = 15.5 inches

height of Kenneth cage can be calculate as follows:

5250 = 20 × 15 × h

5250 = 300h

h = 5250 / 300

h = 17.5 inches

height difference = 17.5  - 15.5 = 2.0 inches

Hence, speedy cage is 2 inches taller than fluffy cage.
