Answer:

2x  -8  =6

     

add 8 to -8 and 6.

the 8s cancel each other out and 6 +8 =14.

next you are going to divide 2x diveded by 2 and 14 by 2. the twos cancel out so its just x and then 14/2 is 7.

the answer is 7. hope this helps dude.

Answer:

7

Step-by-step explanation:

Move the -8 to the other side and use the rule change side change sign:

2x=6+8

2x=14

Move the 2 and convert the multiplication(as its 2×x ) into division:

x= 14÷2

x=7

When numbers are very small or very large, it is convenient to either express the value in scientific notation and/or by using a
finlep [7]

\boxed{ \ 5.0 \times 10^{-3} \ grams \rightarrow 5.0 \ milligrams \ }

<h3>Further explanation </h3>

Scientific notation represents the precise way scientists handle exceptionally abundant digits or extremely inadequate numbers in the product of a decimal form of number and powers of ten.  

Put differently, such numbers can be rewritten as a simple number multiplied by 10 raised to a certain exponent or power. It is a system for expressing extremely broad or exceedingly narrow digits compactly.

Scientific notation should be in the form of  

\boxed{ \ a \times 10^n \ }

where  

\boxed{ \ 1 \leq a \ < 10 \ }

The number "a" is called "mantissa" and the exponent "n" the order of magnitude.

The exponent tells about the size of the number.

  • A positive exponent indicates a number greater than or equal to 1.
  • A negative exponent indicates a number between 0 and 1.

From the key questions asked, we face the standard form of 0.005 grams which will be converted into scientific notation.  

0.005 = \frac{5}{1,000}

  • The coefficient (or mantissa) is 5, which has fulfilled the interval 1 ≤ a < 10.  
  • The denominator consists precisely of three zero digits.

Hence, 0.005 grams is written in scientific notation as  \boxed{ \ 5.0 \times 10^{-3} \ grams \ }

Because 1 milligrams is equal to 10^{- 3} grams, then

5.0 \times 10^{-3} \ grams \times \frac{1 \ milligrams}{10^{-3} \ grams}

Hence, 0,005 grams is 5.0 milligrams.

In science, we frequently must deal with extremely small or incredibly large quantities. For a typical example, one of the recognized limitations of the microwave frequency is 300,000,000 Hz with a photon energy of 0.00000124 eV. They with many zeros can be impractical to work with, so scientists properly implement scientific notation.

The inverse of scientific notation is the standard form. To promptly change scientific notation into standard form, we reverse the process, move the decimal point to the right or left. This expanded form is called the standard form.

\boxed{ \ 3.0 \times 10^{8} \ Hz \ \rightarrow 300,000,000 \ Hz \ or \ 300 \ MHz \ }

\boxed{ \ 0.00000124 \ eV \ \rightarrow 1.24 \times 10^{-6} \ eV \ or \ 1.24 \ \mu eV \ }

The table represents a function.
mezya [45]

Answer:

-8

Step-by-step explanation:

You are given the following table representing the function f(x):

\begin{array}{cc}x&f(x)\\-4&-2\\-1&5\\3&4\\5&-8\end{array}

This means

f(-4)=-2\\ \\f(-1)=5\\ \\f(3)=4\\ \\f(5)=-8

Hence,

f(5)=-8

A street has parallel curbs 40 feet apart. A crosswalk bounded by two parallel stripes crosses the street at an angle. The lengt
andreev551 [17]

Answer:

The distance, in feet, between the strip = 12 feet.

Step-by-step explanation:

From the figure attached in relation with the question, we can deduce that crosswalk is a parallelogram where

CD/AB = CE/AE

CD = 40

CE = 50

AE = 15

Let AB = x

50x = 15 × 40

X = 12

 The distance, in feet, between the strip is therefore 12 feet
