Step-by-step explanation:
3x+5=4
move the positive number to the right side over the equal sign.
NB.lf the number that u moved over is positive(it as a plus sign before it ) the number will become negative when moved over the equal sign. If the number has a minus sign then when it is moved over the equal sign it becomes positive.
so for this because we have a +5.it will then be
3x=4-5
3x=-1
To get x you divide both side by 3
3x/3=-1/3
therefore x =-1/3
Answer: Standard Deviation.
Step-by-step explanation:
DescriptionIn insights, the standard deviation is a proportion of the measure of variety or scattering of a lot of qualities. A low standard deviation demonstrates that the qualities will in general be near the mean of the set, while an elevated expectation deviation shows that the qualities are spread out over a more extensive territory.
I think i
the answer is d and if it’s more i’m so sorry
X-y=50 and 2x=3y
x=y+50 so 2(y+50) = 3y
2y+100=3y
y=100
x-100=50
x=150
so our numbers are 150 and 100
150-100=50 and 150 is 3*50 and 100 is 2*50 so fits all requirements!
hope this helps you! thank you!
