Do same-side interior angles have to be on the same (in this case) horizontal line?

2 answers:

if the horizontal lines are all parallel, then yes, as long as the angles are on the same side. If the horizontal lines are parallel but the angles are on opposite sides, then no. If the horizontal lines are not parallel, then it would require more work to figure it out

Yes because it’s called same side interior so same lineee

I totally forgot how to do #4. Can you plz explain?

Dahasolnce [82]

The answer is F because you would have to multiply both 4 and 3 to get 12. Then you add both of the exponents for X to get 5. You wouldn't have to do anything for Y because you can't add it to anything.

What is the solution to {2x +3y=11 and 3x+3y=18

ra1l [238]

Answer:

The ordered pair that satisfies the equation is (7, -1)

Step-by-step explanation:

In order to find this, we can solve by subtracting. Start by stacking the two equations on top of one another and subtracting like terms.

3x + 3y = 18

(-) 2x + 3y = 11

--------------------

x = 7

Now that we have the value for x, we can plug in to either equation to find y.

2x + 3y = 11

2(7) + 3y = 11

14 + 3y = 11

3y = -3

y = -1

The mean of a list of test scores is 80. Adding an additional test score of 92 caused the mean to rise to 82. After this additio

miv72 [106K]

Answer:

6

Step-by-step explanation:

The mean of a list of test scores is 80

Adding an additional test score of 92 caused the mean to rise to 82

To find:

After this additional, how many total test are in the list ?

Solution:

Let the total number of test at first = $n$

And sum of total score = $S$

As we know, mean = $\frac{sum \ of \ total \ observation}{number\ of \ total\ observation}$

$80= \frac{S}{n} \\$

Multiplying both sides by $n$

$80n=S$

Now, as adding an additional test score of 92 caused the mean to rise to 82,

$S+92=82\times(n+1)\\80n +92 = 82n+82 \ (given \ S =80n)$

$80n-82n =82-92\\-2n=-10$

By dividing both sides by minus ( - )

$2n =10$

By dividing both sides by 2

$n =5$

Thus, total number of test at first = $n$ = 5

And, after this additional score added, total number of tests are $n+1=6$
