-2x - x + 8 = ? a little help please!

2 answers:

8 0

First you would want to add all like terms. So add -2x and -x which will give you the equation -3x+8=?. Now you want to get 8 on the other side to simplify the equation even more so subtract 8 on both sides. -3x=-8. Finally you want to isolate x by dividing by -3 on both sides which will leave you with x=8/3 or x=2 2/3

Step-by-step explanation:

Sum of interior angles of a pentagon = 540°

Therefore,

2x° +2x° + 3x° + 3x° + 10 = 540°

10x° + 10° = 540°

10x° = 540° - 10°

10x° = 530°

10x = 530

x = 530/10

x = 53

The price of a mobile phone decreased from $375 to $250 during a clearance sale. What is the percent of decrease in the price?

Tresset [83]

So decrease is 375-250=75

so convert 75/375 to percent
percent means part out of 100 so
x/100=x%

divide 125/375=0.3333/1

multiply by 100/100=33/100=33%

the answer is 33% or B
