Answer:

x = 39

Step-by-step explanation:

To solve for x, we have to get it by itself in the equation.

In this problem, we have to do the opposite of subtraction and add 36 to the left and right side of the equation.

3 + 36 = x - 36 + 36

36 + 3 is equal to 39 and -36 + 36 cancels out.

This leaves us with 39 = x.

A right triangle has a side with length 12 in and a hypotenuse with length 20 in. find the length of the missing leg. (round to
OLEGan [10]
Let the unknown side be "z" inches
Through pythagoras:
{12}^{2}  +  {z}^{2}  =  {20}^{2}
Because the square of the two sides add up to the square of the hypotenuse in a right triangle.

This means that
{z }^{2}  = {20}^{2}  -  {12}^{2}
{z}^{2}  = 400 - 144 = 256
z =  \sqrt{256}  = 16
So the missing side is 16 inches

Can someone please simplify 3 1/3 divided by 2 2/5 please
satela [25.4K]

Simplify the following:

(3 + 1/3)/(2 + 2/5)

Put 2 + 2/5 over the common denominator 5. 2 + 2/5 = (5×2)/5 + 2/5:

(3 + 1/3)/((5×2)/5 + 2/5)

5×2 = 10:

(3 + 1/3)/(10/5 + 2/5)

10/5 + 2/5 = (10 + 2)/5:

(3 + 1/3)/((10 + 2)/5)

10 + 2 = 12:

(3 + 1/3)/(12/5)

Put 3 + 1/3 over the common denominator 3. 3 + 1/3 = (3×3)/3 + 1/3:

((3×3)/3 + 1/3)/(12/5)

3×3 = 9:

(9/3 + 1/3)/(12/5)

9/3 + 1/3 = (9 + 1)/3:

((9 + 1)/3)/(12/5)

9 + 1 = 10:

(10/3)/(12/5)

Multiply the numerator by the reciprocal of the denominator, (10/3)/(12/5) = 10/3×5/12:

(10×5)/(3×12)

The gcd of 10 and 12 is 2, so (10×5)/(3×12) = ((2×5) 5)/(3 (2×6)) = 2/2×(5×5)/(3×6) = (5×5)/(3×6):

(5×5)/(3×6)

3×6 = 18:

(5×5)/18

5×5 = 25:

Answer: 25/18

Identify the range of the function y=4x-2 domain={-1,-2,-3,-4}​
olga55 [171]

Answer:

<h2>The range: {-6, -10, -14, -18}</h2>

Step-by-step explanation:

Put the values of x from the domain to the equation of a function y = 4x - 2:

for x = -1

y = 4(-1) - 2 = -4 - 2 = -6

for x = -2

y = 4(-2) - 2 = -8 - 2 = -10

for x = -3

y = 4(-3) - 2 = -12 - 2 = -14

for x = -4

y = 4(-4) - 2 = -16 - 2 = -18
