Solve each System by substitution y=-5 5x+4y=-20

Answers

Answer 1

Answer: if you mean what is x if y=-5 so you should just do like:
5 x + 4 ( -5 ) = -20 ⇒ 5 x -20 = -20 ⇒5 x = 0 ⇒ x=0 :))
i hope this be helpful

Answer 2

Answer: In substitution, we need to replace the value of the variable and them solve.

y= -5

5x + 4(-5) = -20
5x + -20 = -20

Now do the inverse operation.

5x - 20 = -20
+20 +20

5x = 0
5x/5 = 0/5
o divided by 5 is o.

x= 0 and y = -5

Which measurement is equivalent to 1/2 gallon?128 fl. oz.
16 cups
2 quarts
8 pints

Answers

If you would like to know which measurement is equivalent to 1/2 gallon, you can calculate this using the following steps:

1 gallon = 128 fl. oz.
1 gallon = 16 cups
1 gallon = 4 quarts
1 gallon = 8 pints

1/2 gallon = 1/2 * 128 fl. oz. = 64 fl. oz.
1/2 gallon = 1/2 * 16 cups = 8 cups
1/2 gallon = 1/2 * 4 quarts = 2 quarts
1/2 gallon = 1/2 * 8 pints = 4 pints

Equivalent: 2 quarts.

Answer:

2 quarts is the answer

Find the GCF of the given polynomial.

16a4b4 + 32a3b5 - 48a2b6

Answers

16a^4b^4 + 32a^3b^5 - 48a^2b^6

the GCF would be : 16a^2b^4....because the 16 is the highest coefficient that goes into 16,32,and 48. Then u just take the a with the smallest exponent and the b with the smallest exponent.

Simple.....

once you factor the expression completely you should get...

$16a^(2) b^(4) (a-b)(a+3b)$ ------> $16a^(2) b^(4)$ is your GCF.

Thus, your answer.

How to solve equation with one variable

Answers

An equation has an equal sign. This makes it possible to find the one value the variable can be to "balance" the equation.

To solve an equation, we isolate the variable (get the variable by itself on one side of the equation). This is done by "undoing" the operation on the variable.

Example - $x+5=18$

$x=18-5$ $| isolate |$

$x = 13$

Hope this RANDOM example helps u understand the concept better
