Question 14. When solving the equation -14 = 7x + 6 what will the next stage of your working be?
mr_godi [17]

Answer:

You would subtract 6 from each side.

Step-by-step explanation:

- 14 = 7x + 6

Subtract 6 from each side:

- 14 - 6 = 7x + 6 - 6

7x = - 20

Divide each side by 7:

7x ÷ 7 = - 20 ÷ 7

x = 2 and 6/7

Help PLZ<br><br> I just need an answer it doesn't have to be correct.
Anestetic [448]

Answer:

you can decide if you want this answer or not  :D

Step-by-step explanation:

1st  , notice that our problem is about an eight part whole.  I mean,  the questions are around an object of 8 parts.  so start thinking 1/8 ths

A) asks about P(7)  ... they want to know.. how often the spinner will land on 7. so if it's totally random, 7 will happen just as likely as any of the other numbers so 7 will happen  1/8 th of the time

as a fraction  it's  1/8  as a decimal it's 0.125 and as a percent it's 12.5 %

B) asks about  P(2 or 6 )   [ btw, p here stands for probability ]  

so it's  1/8 + 1/8 =  1/4  or one quarter of the time we would get a 2 or a 6

as a fraction it's  1/4  , as a decimal it's 0.25  and as a percent it's 25%

C)   asks  about P( greater than 4)  or  P( >4)   so that's the whole left side of the circle :0  

as a fraction it's 1/2  as a decimal it's 0.5  and as a percent   it's 50%

D) P( not a 5) or P( ~=5)  so every thing but a 5

as a fraction that's 7/8  as a decimal it's 0.875 and as a percent that 87.5 %

I'll take the odds on that last one to win the lottery plz  :)

What is the y-intercept of the graph of the given line by the equation 3y+4x=15?
irakobra [83]
The answer is A: 5

The y-intercept is when x = 0

<span>3y + 4x = 15
x = 0

3y + 4 * 0 = 15
3y + 0 = 15
3y = 15
y = 15/3
y = 5</span>
