Answer:

x = 15

Step-by-step explanation:

the 2 angles are a linear pair and sum to 180° that is

8x - 3 + 4x + 3 = 180

12x = 180 ( divide both sides by 12 )

x = 15

Rachel works at a bookstore. On Tuesday, she sold twice as many books as she did on Monday. On Wednesday, she sold 6 fewer books
natali 33 [55]
Let m = the amount books Rachel sold on Monday.
then t = the amount books Rachel sold on Tuesday.<span>
then w = </span><span>the amount books Rachel sold on Wednesday.

On Tuesday she sold twice as she did on Monday.
 t = m * 2

On Wednesday she sold 6 fewer books than she did on Tuesday
w = t - 6

Now for the fun.

t = m * 2
w = t - 6

Substitute t for real value

w = m * 2 - 6

Now solve for m.

w - 6 = m * 2 <-- Transpose the 6
(w-6)/2 = m <-- Transpose the 2.
m = (w-2)/2 < The Law of Reflexive Property of Equality</span>

Grace [21]

Answer: 75\%

Step-by-step explanation:

You know that the ratio of the television's screen is 5:4 . This ratio can be also written as the following fraction:

\frac{5}{4}

The television shows an image with a ratio of 20:12 which can be also written as a fraction:

\frac{20}{12}

Set up the following proportion and solve for "x":

\frac{20}{x}=\frac{5}{4}\\\\x=\frac{4*20}{5}\\\\x=16

Now, in order to find the percent of the screen area occupied make the following division:

\% occupied=\frac{12}{16}*100=75\%
