sorry if I am wrong just let me know please

Answer:

x = 1, y = -1, z = 3

Step-by-step explanation:

x - 2y + 2z = 9

y + 2z = 5

z = 3

According to the last equation, z is equal to 3 so we can plug that in and our new 2 equations will be:

x - 2y + 6 = 9

y + 6 = 5

We can subtract 6 from both sides of the second equation to end up with:

y = -1

Now plugging this into the first equation, we have:

x + 2 + 6 = 9

x + 8 = 9

Subtract 8 from both sides

x = 1

Answer: a. 1 1/2   b. 9.6

Step-by-step explanation:

Answer:

There would be 30 black cars.

Since the ratio is 1:5

And we know that there are 6 red cars,

we basically just input it in our ratio

so it would look like 6:x

Now, we just have to plug in for x.

To do that, you have to multiply 6 by 5

To match the ratio.

So that would give us 6:30

And if we divide by 5 we should get our original ratio.

I know this seems confusing haha, but I hope you get it, it's not as hard as it looks !!

Answer:

13

Step-by-step explanation:

Answer:

2/5

Step-by-step explanation:

Rearrange terms:

4(2 + a) = 24a

4(a + 2) = 24a

Distrbute:

4(a + 2) = 24a

4a + 8 = 24a

Subtract 8 from both sides of the equation:

4a + 8 = 24a

4a + 8-8 = 24a-8

Simplify:

4a = 24a - 8

Subtract 24a from both sides of the equation:

4a = 24a - 8

4a - 24a = 24a - 8 - 24a

Combine like terms:

-20a = -8

Divide both sides of the equation by the same term:

-20a = -8

-20a/-20 = -8/-20

Simplify:

Cancel terms that are in both the numerator and denominator

Divide the numbers

a = 2/5

I hope that helps! :D

Answer:

tTe answer is 1.96%

Step-by-step explanation:

given data

change in price/gain= $1.86

the closing price = $94.86

Required.

The percent rise.

Step two:

The formula for the percent rise is

=change/close price*100

substitute our given data

= 1.86/94.86*100

=0.0196*100

=1.96%

Answer:

[tex] \frac{6}{9} [/tex]

or

[tex] \frac{2}{3} [/tex]

Step-by-step explanation:

There are nine in total and she has eaten 6, so the fraction would be 6/9.

If you need to simplify it it would be 2/3.

Answer:

thats a statement

Step-by-step explanation:

Answer:

Option C - 2x + y > 2

Step-by-step explanation:

We don’t have to do some serious math here. We can already eliminate half of the options just looking at it, because the graph has a dotted line, which means it does not include those values.

So, choses A and B are eliminated because the inequality shows the ≥ and ≤ symbol, which means that it does include those values. It’s either C or D because they have the > and < symbol, which means that the inequality does not include those values.

To have a better look at the inequalities, write them in slope-intercept form, which is y=mx+b:

Option C: y > -2x + 2

Option D: y < -2x +2

Just looking at the inequlaity symbol, we can tell that Option C is the correct one because it shows that all the y-values are greater than -2x + 2. Which is true because it’s shaded above the line. When it’s shaded above the line, it means that the y-values are greater.

To make sure my answer was correct, I graphed Option C. The image below shows Option C (2x + y > 2) graphed.

Hope this helps! :)
