Answer:

Step-by-step explanation:

X - 3(2x - 7) = 76

Opening bracket

X - 6X + 21 = 76

-5X = 76 - 21

-5X = 55

X = 55/-5

X = -11

Answer:

To solve this equation your goal is to get x by itself

First we need to distribute the 3 through the (2x-7)

x-6x+21=76 (-3*2x=-6x, -7*-3=21)

Your next step is to combine like terms

-5x+21=76 (x-6x=-5x)

Next subtract 21 from both sides

-5x=55 (21-21=0, 76-21=55)

Last you need to divide both sides by -5

x=-11 (-5/-5=1, 55/-5=-11)

x=-11

Hope this helps ;)

15=7x+3-5x
15= 7x-5x + 3
15 = 2x + 3
-3 + 15 = 2x

Your sister helped you get a dream job at a designer clothing store and one of the perks of the job is that you get 15% off all
Arturiano [62]

Answer:

$197.30 revenue.

Step-by-step explanation:

As long as we realise that 15% = $237.50 total revenue - 15% of that revenue $40.20 and the other 15% was totaled prior and kept to one side as seen as expenditure.

revenue = r  clothing purchase = p

r = (25 x 10 -12.50) - (p15% of e235)

r = (250 - 12.50) -( e235- p23.5 +11.73)

r = (237.50) - (expenditure 235- p35.73)

r = 237.50 -(expenditure 199.27)

r= 237.50

e = 199.27

p = 35.73

Answer with out including expenditure your sister revenue was $237.50

The 15% deduction cannot be confused with the deduction from clothes.

If we were to calculate 15% of $237.50 this would be 23.7+ 16.85 =$40.2

A different  Salary related 15% contribution payments = $40.20

If these were taken from $237.50

Then $237.50- $40.20 = $197.30 revenue, but we do not have to show expenditure in the total only the workings, which is still owed being $199.27- $40.20 already paid towards.

Extension = This means because $40.20 was deducted then expenditure still to be deducted outside of the question would be   e. $199.27 - $40.20 = 159.07 still owed. Saying that the 15% was to pay your sisters contribution to the clothes and not to the state.

a total of 408 tickets were sold for the school play. They were either adult tickets or student tickets. The number of students
Mama L [17]
<span>Given Situation:
=> There are 408 total of ticket sold for a school play
=> 3 times of the tickets are sold to students compare to the adults
=> So the ratio of the given situation is 1 : 3
=> Now, 1 + 3 = 4
Since, we need 4 parts, let’s divide 408 by 4
=> 408 / 4 = 102 – the number of tickets for adults
=> 102 x 3 = 306 – the number of tickets for students
=> 102 : 306</span>

Suppose researchers test 100 college students, whose ages range from 18 to 23. They also test 100 people at a nearby community c
prisoha [69]

Answer:

b. You would conclude that the differences in the average scores can be traced to differences in the working memory of the two groups.

Step-by-step explanation:

Though the average scores of the two sets could have lead to various conditions, but retentive ability deminishes with respect to an increase in age. With respect to the age of the elderly people involved, it is expected that some of them would not be able to retain information for a long period of time. Thus, their average score is 72%.

The college students' are younger, so it is expected that they should be able to retain more information. That ability is one of the reasons why their average score is 85%.

It can be concluded from the research that the differences in the average scores is probably due to the working memory of the two groups.
