The distribution of 4 in the following expression (5+s)4
ruslelena [56]

Answer:

( 5 + s ) 4 = 20 + 4 s

Step-by-step explanation:

<u><em>Distribution property</em></u>

Let a, b and c are numbers then distribution property is defined by

a( b + c) = a b + a c

(a+ b) c = a c + b c

Given that

( 5 + s ) 4 = 5× 4 + s× 4

               = 20 + 4 s

<u><em>Final answer:-</em></u>

( 5 + s ) 4 = 20 + 4 s

6x+5y=120, 7x+11y=202 solve for x and y
Talja [164]
6x=120-5y -> x=20-5/6*y -> 7(20-5/6*y) + 11y =202 -> 140-35/6*y + 11y = 202 -> 140+31/6*y=202 -> 31/6*y = 62 -> y = 12.

How would u do 1 over 3 y + 1 over 4 = 5 over 12? I forgot my notes:(
malfutka [58]
Is it
\frac{1}{3y} + \frac{1}{4} = 5
or
\frac{1}{3} y + \frac{1}{4} = 5
?

both start out the same, just remember what you do to one side you have to do to the other, so subtract both sides by 1/4, then you want to get y alone, so either divide or multiply the 3 on both sides! let me know which it is and I can help you out more

[edit] it's the second, and not going to use cross multiplication.
added a picture that walks you through it :)
