6y-5=11
Move -5 to the other side. Sign changes from -5 to +5.
6y-5+5=11+5
6y=11+5
6y=16
Divide by 6 for both sides to get y by itself.
6y/6=16/6
Cross out 6 and 6, divide by 6 and then becomes 1*1*y=y
y=16/6
Reduce 16/6 by dividing by 2
16/2=8
6/2=3
Answer: y=8/3 or y=2 2/3
Answer:
3/5
Step-by-step explanation:
We want to find 3/4 of 4/5.
The keyword <em>of</em> tells us that we need to multiply. Therefore:
Multiply:
So, 3/4 of 4/5 is 3/5.
We can confirm this by converting them to decimals.
4/5 is 0.8.
3/4 is 0.75.
0.75 or 75% of 0.8 is indeed 3/5 or 0.6.
X = unknown number
10x - 16 = 2x
Subtract 10x from both sides to isolate the variable on the right side of the equation.
-16 = -8x
Divide both sides by -8 to get x alone.
2 = x
Step-by-step explanation:
f'(x) is usually used in calculus to denote the first derivative of f(x) so f'(2) will simply be the first derivative of f(2).
f(x)=x+3
f'(x)=1
thus x does affect the first derivative and your answer for f'(x)=1
