Answer:

Step-by-step explanation:

-8x + 14 = -2(4x - 7)

use the distributive property to get rid of the parentheses (-2 x 4x and -2 x -7) (negative times negative equals positive)

-8x + 14 = -4x + 14

subtract 14 on both sides to cancel out 14

-8x is not equal to -4x

although this may seem like a weird answer, if x is the same variable (pretend it's one) 1 multiplied with -8 will not equal 1 multiplied with -4

Answer:

all real numbers

Step-by-step explanation:

Given

- 8x + 14 = - 2(4x - 7) ← distribute parenthesis

- 8x + 14 = - 8x + 14

Since both sides are equal, then any real value of x is a solution of the equation.

In 2001 , chipper had 102 runs batted in. In 2008, Chipper had only 75 runs batted in. Calculate the percent change in runs batt

DerKrebs [107]

Answer:

The percent change in runs batted in from 2001 to 2008 is 26.47%

Step-by-step explanation:

The number of runs chipper batted in the year 2001 = 102 runs

The number of runs chipper batted in the year 2008 = 75 runs

Here, so the Change in the runs batted

= Runs Batted in year 2001 - Runs batted in the year 2008

= 102 runs - 75 runs = 27 runs

Now, The percentage change in the run = $= \frac{\textrm{Change in the batted run from 2001 to 2008}}{\textrm{Total number of batted runs in 2001}} \times 100$

= $\frac{27}{102} \times 100 = 26.47$

or, The percentage change = 26.47%

Hence, the percent change in runs batted in from 2001 to 2008 is 26.47%

lina2011 [118]

Answer:

Step-by-step explanation:

Given that

19 + 7 divided by 2 - 5

So if we solve this we have to apply proper brackets

= (19 + 7) ÷ 2 - 5

= 26 ÷ 2 - 5

= 13 - 5

= 8

After solving this the answer is 8
