Suppose y varies directly with x if y=27 when x=3 what is y when x=5
Sindrei [870]

The value of y when x = 5 is 45

<h3><u>Solution:</u></h3>

Given that y varies directly with x. This can be written mathematically as:

y  ∝  x

y = k \times x  ---- eqn 1

Where "k" is the constant of propotionality

Given y = 27 when x = 3. Substitute these values in eqn 1

27 = k \times 3\\\\k = \frac{27}{3} = 9

<h3>k = 9</h3>

Substitute k = 9 in eqn 1

y = 9x ----- eqn 2

<u><em>To find: y = ? and x = 5</em></u>

Substitute x = 5 in eqn 2

y = 9 \times 5 = 45

Thus the value of y when x = 5 is 45

Given the following formula, solve for I.<br><br> P = 2(1 + 6)<br><br> PLEASE HELP!!!
Pepsi [2]

Step-by-step explanation

Here ...I'm not too sure about the question as you have written

P = 2 ( 1 + 6 ) and ask to solve for L ...

.So I guess the question you have written is wrong .. ...and I guess there should be L in the place of 1.

...So let me correct the question....

P = 2 ( l + 6 )

P = 2l + 12

P - 2l = 12

- 2l = 12 - P

- 2l = - P + 12

Change the sign of both side of the equation...

2l = P + 12

divide both side by the same number...

L = ( P + 12 ) ÷ 2

l =  \frac{1}{2} p - 12 \times  \frac{1}{2}  \\

Calculate the product of rational numbers...

l =  \frac{1}{2} p - 6 \\
