90 degrees + 5x + x needs to equal 180 degrees cant figure out the variables though

1 answer:

4 0

X=15
90 + 5(15) + 15 = 180
90 + 75 + 15 = 180
180 = 180

To get 15, I added up the the x's (which was 6 total), and divided 90 by them.

90/6 = 15

Then you just fill them into the equation.

Have a superb day!

Point E is between points D and F. If DE = x - 4 , EF = 2x + 5 , and DF = 4x- 8 , find x

horsena [70]

You know that
$DE+EF=DF
(x-4) + (2x+5) = (4x-8)
$

combine like terms $3x+1 = 4x-8
1 = x-8
x=9$

What is 1/144 as an expression using a negative exponent

MrRissso [65]

ANSWER

${12}^{ - 2}$

EXPLANATION

The given expression is

$\frac{1}{144}$

This is the same as:

$\frac{1}{12 \times 12}$

In index notation, we write this as

$\frac{1}{ {12}^{2} }$

To write this as a negative index, we use the property:

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

This implies that;

$\frac{1}{ {12}^{2} } = {12}^{ - 2}$
