Answer:

No, it is not.

Step-by-step explanation:

Answer: The answer is no.

Step-by-step explanation: Plug in the values of -x + y = 1. -3 + 5 [tex]\neq[/tex] 1, and even if the other equation works out, the system of equations would not be valid.

Answer

A. 16.5

Step-by-step explanation:

First you calculate what 45% of 30 is. Then you subtract that from 30.

Answer:

The right answer is B.

Step-by-step explanation:

To be sure if three sides could be used to form a triangle, you need to remember that two sides of a triangle added together is always greater than the final side. B is the only selection that does not work for the law, 3 + 5 = 8 which is smaller than 10, so the corrct answer is B.

Answer:

m = -8

Step-by-step explanation:

have a nice day! :)

Answer:

From this quation:

4m = -32

We need to get m, so we can divide both sides by 4:

4m / 4 = -32 /4

m =  -8

You can try to replace it to see if it's correct:

4 * 8 = -32

Answer:

Step-by-step explanation:

8 x 6 = 48 because you just add a 1

Answer:

[tex]\frac{1}{48}*6 = 1/8[/tex]

Step-by-step explanation:

If  [tex]\frac{1}{8}/6 = \frac{1}{48}[/tex], then, [tex]\frac{1}{48}*6 = 1/8[/tex]

Answer:

x = 10 or x = 2

Step-by-step explanation:

Solve for x:

x^2 - 12 x + 20 = 0

Hint: | Solve the quadratic equation by completing the square.

Subtract 20 from both sides:

x^2 - 12 x = -20

Hint: | Take one half of the coefficient of x and square it, then add it to both sides.

Add 36 to both sides:

x^2 - 12 x + 36 = 16

Hint: | Factor the left hand side.

Write the left hand side as a square:

(x - 6)^2 = 16

Hint: | Eliminate the exponent on the left hand side.

Take the square root of both sides:

x - 6 = 4 or x - 6 = -4

Hint: | Look at the first equation: Solve for x.

Add 6 to both sides:

x = 10 or x - 6 = -4

Hint: | Look at the second equation: Solve for x.

Add 6 to both sides:

Answer: x = 10 or x = 2

Answer:

Step-by-step explanation:

Answer:

yes i think it is

Step-by-step explanation:

Answer:

The answer is 60

Step-by-step explanation:

How to find what percent of X is Y. Use the percentage formula: Y/X = P% Example: What percent of 60 is 12? Important! The result will always be in decimal form, not percentage form.

(i know this isn’t the clearest formula but its what i used)

Answer:

60

Step-by-step explanation:

To make this problem a little easier, think of 80% as 4/5.

(4/5 = 48/x) ~the unknown is represented by x

After cross multiplying, or "the butterfly method" you would get:

4x = 5(48)

4x = 240

240/4 = 60!

Answer:

A- Root 16

B- Root 27
