with that equation in mind
how do we multiply whole number fractions? well, we make them into improper fractions
3 3/4 becomes (4x3) +3 / 4
2 2/5 becomes (2x5) + 2 / 5
Those answers become
15/4 x 12/5
^ Our improper fractions then we multiply across
15/4 x 12/5
^ 15 x 12 = 180
& 4 x 5 = 20
the final fraction becomes 180/20 and we can simplify that by 20
that becomes 9/1 = 9ft^2
3x – 2y = 17
–2x – 5y = 14
Solve using Elimination Please show work
Answer:
The solution is x=3 , y=-4 or (3,-4)
Step-by-step explanation:
Given equations (1 and 2) are:
[tex]3x- 2y = 17\\-2x -5y = 14[/tex]
To solve a system of equation with elimination method, the co-efficients of one of the variables has to be equated and then the equations are added or subtracted to get an equation in one variable.
Multiplying equation 1 by 2:
[tex]2(3x-2y) = 2*17\\6x-4y = 34\ \ \ \ \ Eqn\ 3[/tex]
Multiplying equation 2 by 3
[tex]3(-2x-5y) = 3*14\\-6x-15y = 42\ \ \ \ Eqn\ 4[/tex]
Adding equation 3 and 4
[tex](6x-4y) + (-6x-15y) = 34+42\\6x-4y-6x-15y = 76\\-19y = 76\\\frac{-19y}{-19} = \frac{76}{-19}\\y = -4\\[/tex]
Putting y = -4 in equation 1
[tex]3x-2(-4) = 17\\3x+8 = 17\\3x = 17-8\\3x = 9\\\frac{3x}{3} = \frac{9}{3}\\x = 3[/tex]
Hence,
The solution is x=3 , y=-4 or (3,-4)

Victor read 2 1/3 books over 14 days last summer. Assume it took him the same amount of time to read each book. How many days did it take him to read a full book?
I answered 1/6. Is this correct? I need explanation and answer. Will give the branliest!
Answer:
It took 6 days for Victor to read a full book.
Step-by-step explanation:
Given that Victor read 2 1/3 books in 14 days, and that it took him the same time to read each book completely, to determine the number of days it took him to read a complete book it is necessary to perform the following calculation:
1/3 = 0.333
14 / (2 + 1/3) = X
14 / 2.333 = X
6 = X
So, it took Victor 6 days to read a full book.

The space inside the box around the pyramid is then filled with protective foam. About how many cubic inches of foam is needed to fill the space around
the pyramid?
Your answer:
8 cubic inches
41 cubic inches
83 cubic inches
125 cubic inches
Volume is a three-dimensional scalar quantity. The volume of foam that is needed in cubic inches is 83.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of foam needed is the difference between the volume of the cube and the volume of the square pyramid. Therefore,
The volume of cube = a³ = 5³ = 125 in³
The volume of Pyramid = (1/3)×blh = (1/3)×5×5×5 = 41.667
The volume of foam needed = 125 in³-41.667 in³ = 83.3334 in³ ≈ 83 in³
Hence, the volume of foam that is needed in cubic inches is 83.

You are given 3 to 1 odds against tossing three tails with three coins, meaning you win $3 if you succeed and you lose $1 if you fail. Find the expected value (to you) of the game. Would you expect to win or lose money in 1 game? In 100 games? Explain. Find the expected value (to you) for the game.
Step-by-step explanation:
To find the E(X) expected value, you come up with the different probabilities for each outcomeyour set of outcomes after 3 tosses would be = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} where H is heads and T is tailsEach element has a probability of 1/8 so let x represent number of tails[tex]Probability(x)=P(x)\\P(0)=\frac{1}{8} \\P(1)=\frac{3}{8} \\P(2)=\frac{3}{8} \\P(3)=\frac{1}{8}[/tex] The E(x)=Summation (x times P(x))[tex]E(X)=(0)(0.125)+(1)(0.375)+(2)(0.375)+(3)(0.125)=1.5[/tex] Now which probability is 1.5 tails? None, so it is either 2 tails or 1 tailsSo you can expect to lose money in 1 gameBut as you play more games the probability of getting 3 tails becomes more and more likely, so you can expect to win in a 100 gamesThe expected value is the value of winning made on a game when played overtime. Hence, the expected value of the game is -$0.5 ; with the player losing -$0.5 in the long run.
A coin toss :
{H, T}Sample space for 3 tosses :
{HHH, HHT, HHT, HTT, HHT, HTT, HTT, TTT}Toss required to win = 3 tails :
Amount won on success = $3 Amount lost otherwise = $1 = - $1Creating a discrete probability table :
X _____ 3 _______ - 1P(X) ___ 1/8 _____ 7/8The expected probability can be defined as :
E(X) = ΣX×P(X)E(X) = 3 × (1/8) + (-1) × 7/8
E(X) = 3/8 - 7/8 = - 4/8 = -1/2
Therefore, the expected value of the game = - 0.5 ; meaning that, I'll lose 0.5 in the long run.

You build a model of Laurel Park using the scale 1.5 inches:10 feet. If the model 94.5
inches wide, what is the width of the school campus?
Answer:
The width of the school campus is:
[tex] \boxed{ \underline{ \rm{630 \: feet}}}[/tex]
Step-by-step explanation:
Scale = 1.5 inches : 10 feet
That means, 1.5 inches is equals to 10 feet in real.
Then for 1 inch:
⇛ 10 / 1.5 feet
⇛ 10/3 feet
We need to find for 94.5 inches,
⇛ 94.5 inches = 94.5 × 2/3 feet
⇛ 94.5 inches = 63 feet
Thus, the width of the school campus is 63 feet.

Answer:

Step-by-step explanation:
The improper fraction is ten eighths(10/8).
What is improper fraction?Improper fractions are ones that have been divided improperly for any number, object, or element, as indicated by the term. A fraction is a portion of a whole in mathematics. Denominator and numerator are the two components of fractions.
A fraction whose numerator exceeds the denominator is referred to as an improper fraction. Consider the case where x/y is an improper fraction and x exceeds y. The incorrect fraction is consequently always bigger than one.
Given two times five eighths.
we need to multiply 2 by 5/8
First, remember that 2 is equal to 2/1 since 2 divided by 1 equals 2. Therefore, frame the issue as follows to begin:
2/1 x 5/8
Combine the denominators (1 x 8) and the numerators (2 x 5 = 10) to create a single fraction, as seen below:
10/8
Hence two times five eighths is 10/8 in improper fraction.

Determine the slope of the line represented by the table of values and the y-intercept
The slopes and the y - intercepts of the lines represented by the tables are calculated below.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given are the tables representing the coordinates [x] and [y].
Table [1]
m = (5 - 3)/(-1 + 2) = 2
[y] - intercept = 7
Table [2]
m = (2 - 5)/(-2 + 3) = -3
[y] - intercept = -4
Table [3]
m = (-13 + 17)/(2 - 1) = 4
-1 = 4 x 5 + c
c = - 1 - 20 = - 21
[y] - intercept = - 21
Table [4]
m = (-9 + 4)/(-5 + 6) = - 5
-6 = - 5 x - 4 + c
c = - 26
[y] - intercept = - 26
Table [5]
m = (6 - 3)/(1 - 0) = 3
[y] - intercept = 3
Table [6]
m = (2 - 5)/(-1 + 2) = - 3
[y] - intercept = - 3
Table [7]
m = (6/5 - 2/5)/(0 + 2) = 2/5
[y] - intercept = 6/5
Table [1]
m = (2 - 1)/(1 + 1) = 1/2
[y] - intercept = 1.5
Therefore, the slopes and the y - intercepts of the lines represented by the tables are calculated above.
