which of these shows the result of using the first equation to substitute for y in the second equation, then combining like term

Furkat [3]

Answer:

C. $\Rightarrow \bold{8x = 16}$

Step-by-step explanation:

Given the two equations:

$y=2x ........ (1)\\ 2x+3y=16.......(2)$

To find:

The correct option when value of y is substituted to 2nd equation using the 1st equation.

Solution:

First of all, let us learn about the substitution method.

Substitution method is the method to provide solutions to two variables when we have two equations and two variables.

In substitution method, we find the value of one variable in terms of the other variable and put this value in the other equation.

Now, the other equation becomes only single variable and then we solve for the variable's value.

Here, we have two equations and value of one varible is:

$y=2x$

Let us put value of y in 2nd equation:

$2x+3y=16\\\Rightarrow 2x + 3(2x) = 16\\\Rightarrow 2x + 6x = 16\\\Rightarrow \bold{8x=16}$

So, the correct answer is option C. $\Rightarrow \bold{8x = 16}$

The ratio of my action to comedy movies is 4:5. If I have 35 comedy movies, how many are action? *

iogann1982 [59]

Answer:

28 action movies

Step-by-step explanation:

Set up a proportion: $\frac{4}{5} = \frac{x}{35}$
Cross multiply, then divide: 35 × 4 = 140, 140 ÷ 5 = 28
So, if you have 35 comedy movies, you would have 28 action movies.

I hope this helps!
