Answer:
n = p - m - k
Step-by-step explanation:
p = n + m + k ( isolate n by subtracting m and k from both sides )
p - m - k = n
Answer:
Step-by-step explanation:So we know x + y = 21 and 5x +10y = 165 We line them up in columns x + y = 21 5x +10y = 165 To eliminate the x variable, I'll multiply every element in the 1st equation by -5. -5x + -5y = -105 5x + 10y = 165 Now we combine (add) the equations, which eliminates x altogether. 5y = 60 ... y = 12 From there, x + 12 = 21 ... x = 21-12 ... x = 9 You should double check. Do 9 nickles and 12 dimes equal $1.65? A very important thing to remember using this method is to do the same thing to each element in the equation that you change! I hope that helps.
Answer:
soln,
here,1st and 2nd case for a
1st case
so,a=3/2g.
2nd case
a=2/3g.
3rd and 4th case for X
3rdcase
(U+4)/2=X
X=(U+4)/2.
4th case
X=(U+4)/2.
