Samantha has $48 to spend on used video games. Single player games cost $6 each and multi player games cost $12 each. What equation, in standard form, determines the number of single player games (x) and the number of multi player games (y) Samantha can buy?

Answers

Answer:

The equation is

6x + 12y = 48

Step-by-step explanation:

Standard form another way of writing a linear equation. It is in the form

Ax + By = C

Total amount with Samantha = $48

Single player games = $6 each

Multi player games = $12 each

Let

Number of Single player games = x

Number of Multi player games = y

The number of single player games (x) and the number of multi player games (y) Samantha can buy is

6x + 12y = 48

That is price × quantity of single player games + price × quantity of multi player games = Total amount with Samantha

Solve the equation using the Properties of Equality.

Answer:

m = 11/36

Step-by-step explanation:

6/7 m - 1/7 = 5/ 42

Multiply each side by 42 to clear the fractions

42(6/7 m - 1/7) = 5/ 42 *42

36m - 6 = 5

Add 6 to each side

36m -6+6 = 5+6

36m = 11

Divide each side by 36

36m/36 = 11/36

m= 11/36

At the beginning of the day the stock market goes down 50 1/2 points and stays at this level for most of the day. At the end of the day the stock market goes up 80 1/4 points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the​ day?

Answers

Answer:

The change for the day is 29 3/4

Step-by-step explanation:

In this problem, we are expected to calculate the change in the price of a particular stock

Given that the days high is 80 1/4

and also that the days low is 50 1/2

we can calculate the change by subtracting the days low from the days high

i.e 80 1/4- 50 1/2= 321/4-101/2= (321-202)/4= 119/4 = 29 3/4

hence the change for the day is 29 3/4

Also we can calculate the percentage change as

%change = (high-low)/low*100

%change= 80 1/4- 50 1/2/50 1/2= 29 3/4/50 1/2 *100

%change= 119/4*2/101 *100= 119/202*100= 0.589*100= 58.9%

%change= 58.9%

The length of the actual trail will be 3 and 1/2 miles. The correct option is C.

What is an expression?

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that a trail map has a scale of 3 inches to 2 miles. The length of the actual trail will be calculated as:-

3 inches = 2 miles

1 inch = 2 / 3 miles

5¹/₂ inches = 5¹/₂ x  ( 2 / 3 )miles

5¹/₂ inches = 5.2 x ( 2 / 3 )

5¹/₂ inches = 3.5 miles = ( 2¹/₂) miles

Therefore, the length of the actual trail will be 3 and 1/2 miles. The correct option is C.

After taxes, Alexandra's take home pay is 7 10 of her salary before taxes. Enter and solve an equation to find Alexandra's salary before taxes for the pay period that resulted in $378 of take-home pay. Let s represent your variable.

Answers

Answer:

$540

Step-by-step explanation:

Let s be Alexandria's salary before taxes.

Let t be her take-home after taxes = $378

The question says her take-home is 7/10 of her salary before taxes

So to calculate what her salary was before taxes:

s x (7/10) = $378

We divide both sides by 7/10

S = 378 ÷ 7/10

S = 378x10/7

S = 3780/7

S = 540

Therefore from the calculations above, her salary before taxes was $540
