Step-by-step explanation:

|...| means absolute value of "...". that means always the "+" value of "...", even if it is negative.

in other words

|-x| = x

|x| = x

|-x - 2y| for x = -2 and y = 3

|- -2 - 2×3| = |2 - 6| = |-4| = 4

Find the value of x that makes m ∥ n.

arsen [322]

Answer:

x = 40

Step-by-step explanation:

In order for m and n to be parallel, the corresponding angles need to be equal. Therefore we get the equation:

3x = 120

Divide both sides by 3 to get:

x = 40

A³b² a²b simplify the following expression

liberstina [14]

Answer:

$a^{5}$ $b^{3}$

Step-by-step explanation:

The law of indices can be used to simplify mathematical expressions involving arithmetical operation on variables with powers.

$a^{m}$ x $a^{n}$ = $a^{(m+n)}$

Thus, the given expression can be simplified as follows:

a³b² a²b = a³ x a² x b² x $b^{1}$

= $a^{3+2}$ x $b^{2+1}$

= $a^{5}$ $b^{3}$

Thus,

a³b² a²b = $a^{5}$ $b^{3}$

23 + 8m + 4n - 5m - 27

mylen [45]

Answer:

$-4 + 3m + 4n$

Step-by-step explanation:

In this question, you are combining like terms, meaning doing equations to numbers that fit with only each other.

So we should start on the number without variables:

23 and 27

Match them up together and you should find your first equation:

23 - 7

==> -4

So we should have -4 + 8m + 4n - 5m

Now we should combine the numbers with the variable of m:

8m and 5m

Match them up together and you should find your first equation:

8m - 5m

==> 3m

So we should now have -4 + 3m + 4n

Since there are no other variables of n, we are all done:

-4 + 3m + 4n is your final answer

What is 4 over 10 in simplest form

ahrayia [7]

Ok so find 1's

remember that 4/4=1 also x/x=1 those are ones
also remember
if you had
10/30 that equals 10/10 times 1/3=1 times 1/3

so find ones

4/10=2/2 times 2/5=1 times 2/5=2/5
