Answer:

x = -33/8 or -4 1/8 as a mixed number.

Step-by-step explanation:

1/2x − 3/4(2x+5) = 3/8

1/2x - 3/2x - 15/4 = 3/8

-x = 3/8 + 15/4

-x = 3/8 + 30/8

-x = 33/8

x = -33/8

Can someone help me figure out the slop please !:)

(1,5)&(8,5)
slope =(8-1)÷(5-5)
= 7÷0
the solution is undefined because any number which is divided by 0 is undefined

on the last 5 quizzes, marco has earned a total of 21 out of 25 possible points. if he has a perfect score on the next several q

nevsk [136]

Using the mean concept, it is found that we will need 15 more points to bring up his average up to 90%.

The mean of a data-set is the <u>sum of all observations divided by the number of observations</u>.

In this problem:

In the first 5 observations, total of 21 out of 25 points, hence the mean for these observations is $\frac{21}{25} = 0.84$ .
In the next n observations, mean of 1.

Hence, the mean is:

$M = \frac{0.84(5) + n}{5 + n} = \frac{4.2 + n}{5 + n}$

We want the mean to be of 0.9, thus:

$M = 0.9$

$\frac{4.2 + n}{5 + n} = 0.9$

$4.2 + n = 0.9n + 4.5$

$0.1n = 0.3$

$n = \frac{0.3}{0.1}$

$n = 3$

3 more testes are need, each worth 5 points, hence, 15 more points are needed to bring up his average up to 90%.

What is the slope of the line through ( 3 , 6 ) and ( 4 , 2 )?

Sophie [7]

Answer:

-4

Step-by-step explanation:

To find the slope you have to find the change in y over the change in x:

2 - 6 / 4 - 3 = -4 / 1 = -4 - slope

Lucia deposits $44.60 into her bank account on Tuesday Morning. Tuesday afternoon, she withdraws to $26.30 and $21.30. Does Luis

dexar [7]

Answer:

Less than

Step-by-step explanation:

Using the data from the question, we can create the following equation to solve this...

44.60 - (26.30 + 21.30) = x

44.60 - (47.60) = x

-3 = x

As you can see Lucia withdrew more money than what she actually deposited which means that her account balance on Tuesday Night is less than what it was on Monday night before the initial deposit. This can all be seen using the above equation which is designed.
