The given equation is ⇒ 100 - (1/2) x = 92

100 - (1/2) x = 92 ⇒ Add (-100) to both sides

-100 + 100 - (1/2) x = 92 - 100

∴ -(1/2) x = -8 ⇒ Multiply both sides by (-2)

∴ -2 * (-1/2) x = -8 x -2

∴ x = 16

So, the value of x will be equal 16

Find the value of x

Monica [59]

X= 130°

Step-by-step explanation:

From E, draw EF || AB || CD.

Now, EF || CD and CE is the transversal.

So; <DCE + <CEF = 180° [co. int. <s]

x° + <CEF = 180°

<CEF = (180° – x°).

Again, EF || AB and AE is the transversal.

So; <BAE + <AEF = 180° 01 [co. int. <s ]

105° + <AEC+ <CEF = 180°

105° +25° + (180° – x°) = 180°

x° = 130°

I need help with this question

Bezzdna [24]

Answer:

It is all determined by how many spaces and which way the decimal point moves.

Step-by-step explanation:

So here are two examples

Example 1:

500000.00

To write this in scientific notation you would move the decimal place to the left.

You would move it 5 digits to the left so the exponent of 10 would be 5

$5 * 10^{5}$

Example 2

0.0000042

Here to write this in scientific notation you move the decimal place to the right.

You would move it 6 digits to the right so the exponent would be -6

$4.2 * 10^{-6}$
