Answer:
w = -7/6 u
Step-by-step explanation:
The independent variable is in the equation, we solve for the dependent variable
So we solve for w
4u + 8w = -3u + 2w
Subtract 2w from each side
4u + 8w-2w = -3u + 2w-2w
4u+6w = -3u
Subtract 4u from each side
6w = -3u-4u
6w = -7u
Divide by 6
6w/6 = -7u/6
w = -7/6 u
Answer: 8.99mm
Step-by-step explanation:
a^2 + b^2 = c^2
Answer:
8/9
Step-by-step explanation:
add two fractions, such as 2/9 + 2/3, make sure that the two denominators are the same and then we simply add the numerators.In cases where the denominators are not the same, you would find the lowest common denominator and adjust the fractions to keep them intact.
Since y=7x we can replace the y in the second equation with 7x
-5x+14x=9
x=1
Now plug in to get 7 for y, since 7x=y
Answer: x=1, y=7
^ if you're talking universally, no it would be cm. But no one really says "quarter inches". You would just say inches
