Answer: x = 17.5

Step-by-step explanation:

All expressions for the angles as a whole must equal 180 because it is on a line.

so we need to set all the expressions equal to 180 then solve.

4x+2x+30+2x+10=180

combine like terms

(4x+2x+2x) + (30+10) =180

8x + 40 = 180

now subtract 40 from each side

8x=140

isolate the x by dividing each side by 8

x = 17.5

Find the perimeter of the figure

sergiy2304 [10]

Answer:

142

Step-by-step explanation:

Ok explanation

we know the sides 9, 11, 38, and 13.

there are 2 missing sides we need to find

so the first one whic is the longer one is we know that the 38 is already 1 part of it but not the whole thing. We know the 9 is part of the 38 since it connects. So that gives us that side of 47.

Now for the shrter side, we know 1 part of it is 13 And the other part is 11. So we Add them up and get 24

Now the sides are 9, 11, 38, 13, 47, and 24

We add them up and get 142

Which expression is equivalent to 36^-1/2

inn [45]

ANSWER

$( {36})^{ (- \frac{1}{2}) } = \frac{1}{6}$

EXPLANATION

The given expression is

${36}^{( - \frac{1}{2} )}$
This is having a negative index. We must first of all change to a positive index.

Recall that,

${a}^{ - m} = \frac{1}{ {a}^{m} }$

We apply this law of exponents to get,

${36}^{( - \frac{1}{2} )} = \frac{1}{ {36}^{( \frac{1}{2} )} }$

We cab rewrite the given expression to obtain;

${36}^{( - \frac{1}{2} )} = \frac{1}{ \sqrt{36} }$

This will simplify to give us,

${36}^{( - \frac{1}{2} )} = \frac{1}{ 6 }$

Is 3/5 equivalent to 0.35

marin [14]

3/5 is equivalent to 0.6
This is because if you times 2 to the numerator and denominator(top and bottom of the fraction) you will get 6/10 which is 0.6

In the equation 9 more than 3 times a number is -6, what does a number equal

atroni [7]

So 9 more than 3 times a number, would be:
9+(3x)=-6
then you would solve
subtract 9 from 9 and 9 from -6
you get 3x=-15
divide by 3 on both sides
x=-5

your welcome!!!! :)
