Tema [17]

Answer:

I believe the answer is c. but I'm not too sure.

Step-by-step explanation:

my reasoning for this is because it's the chart that is constant. y starts out with 5=0.5 & they add five more on y's side. & x increased the same amount throughout the chart.

For the following system, use the second equation to make a substitution for y in the first equation. 3x + y = 1 y + 4 = 5x What

Debora [2.8K]

Answer:

The answer is A.

Step-by-step explanation:

So we have the two equations:

$3x+y=1\\y+4=5x$

To make a substitution of the second equation into the first equation, we need to isolate the <em>y </em>variable in the second equation. Thus:

$y+4=5x\\y=5x-4$

Now, we can substitute this into the first equation. Therefore:

$3x+y=1\\3x+(5x-4)=1\\3x+5x-4=1$

6 9/10 x 20/21<br> Simplify your answer completely and change to a mixed number.

Sidana [21]

Answer:

$6\frac{4}{7}$

Step-by-step explanation:

Hello,

I am going to start with to change to a improper fraction:

1. I will convert 6 and 9/10 into a improper fraction:

$69/10$

2. Now that I have converted the mixed fraction into a improper I can multiply the numerator and the denominator.

$69 * 20 / 21 * 10 = 1380/210$

3. Now I can simplify this value and convert it into a mixed fraction

$46/7$

After further simplifying I can convert this into an mixed number

$6\frac{4}{7}$
