Answer:
14x² + 7y - 22
Step-by-step explanation:
Combine like terms.
5x² - 6y - 22 + 13y + 9x²
5x² + 9x² = 14x²
-6y + 13y = 7y
Reorder the terms.
14x² + 7y - 22

One fifth of one number and one fourth of a number are added, the result is 29. What is the original number?
Answer:
[tex] \dfrac{580}{9} [/tex]
Step-by-step explanation:
[tex] \dfrac{1}{5}x + \dfrac{1}{4}x = 29 [/tex]
[tex] \dfrac{4}{20}x + \dfrac{5}{20}x = 29 [/tex]
[tex] \dfrac{9}{20}x = 29 [/tex]
[tex] x = 29 \times \dfrac{20}{9} [/tex]
[tex] x = \dfrac{580}{9} [/tex]
Answer: [tex] \dfrac{580}{9} [/tex]
Solve five and two thirds times three fourths
A) three and eleven twelfths
B) four and one twelfth
C) four and three twelfths
D) five and one twelfth
Answer:
C. The answer can be simplified.
Step-by-step explanation:
5 2/3 x 3/4
(5 x 3) + 2 = 17/3
17/3 x 3/4 = 51/12
51 ÷ 12 = 4 3/12
4 3/12 = 4 1/4
So it is C.

Prices for a day ticket entrance at the Disneyland Paris Resort are as follows: Work out the percentage discount offered with the family ticket option.
Answer:
15% discount
Step-by-step explanation:
To find the discount first we need to find out the cost without the family ticketNow the family ticket covers 2 Adults and 2 children, but how much is that using the standard prices?So [tex]2adults= 2*(55)=110[/tex] which is Euros I believeThen [tex]2children= 2*(45)=90[/tex] We add these together 110+90=200 Euros, that's how much 2 adults and 2 children cost with standard pricesNow the family ticket only charges 170 EurosSo how much less is the family ticket to the regular price? 200-170=30 EurosThat's the discount, now what percentage of the actual price 200 Euros, is 30 Euros?First we write it as a fraction; 30 Euros out of 200 Euros which is [tex]\frac{30}{200} =\frac{3}{20}[/tex] To find the percentage, we multiply the fraction by 100[tex]\frac{3}{20} *100=\frac{3*100}{20}=\frac{300}{20} =15percent[/tex] or 15%This just means "take out 15% of 200 from the 200 Euros original price" so that's the percentage discount that the family ticket providesAnswer:

Step-by-step explanation:
A racecar driver is doing a time trial of a new car on a straight back. The car's distance from the timekeeper is represented by y=293x+50 where x is time in seconds and y is the distance from the timekeeper's position. How many feet from the timekeeper is the race car at the beginning?
Answer:
50 feet
Step-by-step explanation:
The car's distance from the timekeeper us given by :
y = 293x+50
Where x is time in seconds and y is the distance from the timekeeper's position.
The general equation of a line is given by :
y = mx +c
On comparing, we get : c = 50
It means the timekeeper has covered 50 feets at the beginning.

represent the given condition using a single variable, x.
The length and width of a rectangle whose length is 15 centimeters more than its width.
The width of the rectangle is ____.
Answer:
Please check the explanation.
Step-by-step explanation:
Let suppose [tex]x[/tex] be the width of the rectangle.
As the length is 15 centimeters more than its width i.e.
[tex]length = x+15[/tex]
Therefore, the width of the rectangle will be:
[tex]x = length - 15[/tex]
CHECK BY EXAMPLE
Let suppose if the length of the rectangle is 20 cm.
Then the width of the rectangle will be:
x = length - 15
= 20 - 15
= 5 cm
Therefore, the width of the rectangle will be 5 cm.
Simplify using the distributive property.
10 - 2(x - 7) = 4(x - 5)
24 - 2 x = 4 x - 20
-4 - 2 x = 4 x - 5
3 - 2 x = 4 x + 5
Answer:x=22 over 3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
10−2(x−7)=4(x−5)
10+(−2)(x)+(−2)(−7)=(4)(x)+(4)(−5)(Distribute)
10+−2x+14=4x+−20
(−2x)+(10+14)=4x−20(Combine Like Terms)
−2x+24=4x−20
−2x+24=4x−20
Step 2: Subtract 4x from both sides.
−2x+24−4x=4x−20−4x
−6x+24=−20
Step 3: Subtract 24 from both sides.
−6x+24−24=−20−24
−6x=−44
Step 4: Divide both sides by -6.
−6x−6=−44−6
x=22 over 3

Step-by-step explanation:
Assume that Jim, Bruce, and Valerie are three of the 19 members of the class, and that three of the class members will be chosen randomly to deliver their reports during the next class meeting. What is the probability that Jim, Bruce, and Valerie are selected in any order?
Answer:
[tex]Probability = \frac{1}{969}[/tex]
Step-by-step explanation:
Given
[tex]Members = 19[/tex]
[tex]Selection = 3[/tex]
Required
Determine the probability of selecting Jim, Bruce and Valerie
First, we need to calculate the possible number of selections.
This is calculated using combination formula:
[tex]Selection = ^nC_r[/tex]
[tex]Selection = ^{19}C_3[/tex]
[tex]Selection = \frac{19!}{(19-3)!3!}[/tex]
[tex]Selection = \frac{19!}{16!3!}[/tex]
[tex]Selection = \frac{19 * 18 * 17 * 16!}{16! * 3 * 2 * 1}[/tex]
[tex]Selection = \frac{19 * 18 * 17}{3 * 2 * 1}[/tex]
[tex]Selection = \frac{19 * 18 * 17}{6}[/tex]
[tex]Selection = 969[/tex]
Selection of Jim, Bruce and Valerie is only 1 selection of the 960 possible selection.
So:
[tex]Probability = \frac{1}{969}[/tex]
The probability that Jim, Bruce, and Valerie are selected in any order is [tex]\rm P=\dfrac{1}{969}[/tex] and this can be determined by using the given data.
Given :
Assume that Jim, Bruce, and Valerie are three of the 19 members of the class and that three of the class members will be chosen randomly to deliver their reports during the next class meeting.
In order to determine the probability that Jim, Bruce, and Valerie are selected in any order, first determine the total number of possible selections.
The total number of possible selections is given by:
[tex]\rm S = \; ^nC_r[/tex]
[tex]\rm S = \; ^{19}C_3[/tex]
[tex]\rm S = \dfrac{19!}{16! \times 3!}[/tex]
S = 969
So, the probability that Jim, Bruce, and Valerie are selected in any order is:
[tex]\rm P=\dfrac{1}{969}[/tex]

It rains on Paradise Island on 40% of the days. The chance of rain is independent from day to day. A travel agent is signing people up to go on a 5-day tour of the island. She wants to know the chance of getting at least two consecutive days of rain at any time during the 5 days. To determine this, a simulation will be used.
Answer:
The probability that it will rain in atleast two consecutive days will be 0.167936.
Step-by-step explanation:
Since it rains on 40% of the days, then the probability of it raining on each day is
This follows a binomial distribution
Since it's a five-day tour and they want to know the probability that rain falls in atleast TWO CONSECUTIVE days then we have to consider 2 days as one, as we do in combination problems, so that they are always together before we use in our binomial probability density function.
Our Probability Density Function is given as
[tex]P(X) = \binom{n}{x} p^x \times q^{n-x}[/tex]
Where p is probability of raining and q = 1 - p is probability of not raining.
Our n is 4 since we are considering two days as one.
We are looking the P(X≥2) = 1 – P(X<2) = 1 – [P(X = 0) + P(X = 1).
[tex]P(X = 0) = \binom{4}{0} 0.4^0 \times 0.6^4 = 0.1296[/tex]
[tex]P(X = 1) = \binom{4}{1} 0.4^1 \times 0.6^3 = 4\times 0.4 \times 0.216 = 0.3456[/tex]
Therefore P(X≥2) = 1 – (0.1296 + 0.3456) = 0.5248.
Remember we combined two consecutive days that it will rain as one, their probabilities will be:
2! x 0.4 x 0.4 = 0.32
Therefore, the probability that it will rain in atleast two consecutive days will be
0.32 x 0.5248 = 0.167936

A lasagna recipe uses 1 2/4 teaspoon basil 1/4 teaspoon pepper and 4 teaspoons parsley if you double the recipe how many teaspoon of seasoning will you use
Answer:
11 1/2 teaspoons
Step-by-step explanation:
1 2/4 basil= 1.5 tsp If you multiply this by two to double the recipe you will have 3 teaspoons of basil.
1/4*2= 2/4 pepper
4*2=8 parsley
After you double everything you need to add them together:
3+2/4+8
Which brings you to the final answer of 11 2/4 teaspoons or if you simplify it.... 11 1/2 teaspoons
