the number isn't large enough to round to the nearest ten thousandths.
that would be the 4th digit to the right of the decimal point, so we would need the 4th and 5th numbers to the right in order to round the answer.
76.2cm : 30in is the answer I think
Answer:
x = 8
Step-by-step explanation:
-1/4 (2x + 8) = -6
Multiply both sides by -4.
2x + 8 = 24
Subtract 8 from both sides.
2x = 16
Divide both sides by 2.
x = 8
Answer:
18 Minutes
Step-by-step explanation:
Simon and sophie each do a fraction of the job per minute like this:
-Simon does per minute (if we multiply this by 30 we have the completed job)
-Sophie does of the job per minute (again if we multiply this by 45 we have the completed job)
We will add this two to know how much of the job they do together in a minute:
They will do of the job per minute.
So the total time will be when they do , we can put this in one equation like this:
where x is the total times we need to do of the job to complete it. We solve for x:
Try this option:
way 1: using the picture, if x=-3 then y=-6.
way 2: the equation of this line is y=x-3; it means that y(-3)=-6.
