Find common denominators. 10 is the common denominator. Multiply 2 to numerator and denominator of -3/5

(-3/5)(2/2) = -6/10

x + 1/10 = -6/10

Isolate the x. Subtract 1/10 from both sides

x + 1/10 (-1/10) = -6/10 (-1/10)

x = -6/10 - 1/10

x = -7/10

-7/10 is your answer for x

hope this helps

The variables y and x have a proportional relationship, and y = 5 when x = 4. What is the value of x when y = 8? Enter your answ

Charra [1.4K]

Answer

Find out the what is the value of x when y = 8 .

To prove

As given

The variables y and x have a proportional relationship.

$y \propto x$

y = kx

Where k is the constant of proportionality.

As y = 5 when x = 4

Put in the above

5 = 4k

$k = \frac{5}{4}$

Now find out the value of x , when y = 8

$8 = \frac{5\times x}{4}$

$x = \frac{8\times 4}{5}$

x= 6.5

Therefore when y = 8 than x = 6.4
