Answer:
The difference of 15 and 4 times a number4a - 15
I want to buy 4 tickets to go to Disney World. They are currently on sale for with a 12% discount.100% representate the original cost of tikets,
100% = 100/100 = 1
12% discont:
12% = 12/100 = 0.12
1 - 0.12 = 0.88
0.88
then the expressión is:
4*0,88d
=3.52 d
d = original cost of each ticket

The sum of two numbers is 6, their difference is 4, find the two numbers. What is their product?
Help as soon as possible. Thanks <3
Answer:
The two numbers are 5 and 1. Their product is 5
Step-by-step explanation:
x + y = 6 (*)
x - y = 4 (**)
Let (*) + (**)
--> (x+y) + (x-y) = 6 + 4
<=> 2x = 10 <=> x = 5
Substitute x= 5
(*) <=> 5 + y = 6
<=> y=1
Answer: (x,y) = (5,1)
Their product: x.y = 5x1 = 5

Write a problem based on the given information.
P = Cost of dinner
0.15p = cost of a 15% tip
P + 0.15p = 23
Answer:
The cost of dinner plus a 15% tip was $23. How much is the dinner?
the cost of the dinner = $20
Step-by-step explanation:
Given that:
p= cost of dinner
0.15p = cost of a 15% tip
p + 0.15 p = 23
The objective is to represent this problem in words based on the given information.
From above, we can say that:
The cost of dinner plus a 15% tip was $23. How much is the dinner?
SO;
p + 0.15 p = 23
1.15 p = 23
Divide both sides by 1.15
p = 23/1.15
p = 20
Therefore, the cost of the dinner = $20

7n +9 = -1+6(n+4)
can someone walk me through this please?
Answer:
n = 14
Step-by-step explanation:
7n +9 = -1+6(n+4)
Distribute
7n+9 = -1 +6n+24
Combine like terms
7n +9 = 6n +23
Subtract 6n from each side
7n -6n+9 = 6n-6n +23
n+9 = 23
Subtract 9 from each side
n+9-9=23-9
n = 14

The linear equation y=45x describes how far tracy is as she drives from san francisco to dawson. Let x represent the number of hours and y represent the number of miles. How far from home is tracy in 12 hours
Answer: 540 miles
Step-by-step explanation:
plug in the numbers into the equation
multiply and ta-da
Answer:
540 miles
Step-by-step explanation:
y = 45(12) = 540
Solve each system by substitution. 6) -8х - бу = 14 y = 4x - 13
A number K is such that when it is divided by 27,30 or 45,the remainder is 3.
Find the smallest possible value of k.
Solution :-
First of all we have to find out the least common multiple of the given three numbers.
27 , 30 and 45
27 = 3 x 3 x 3
30 = 2 x 3 x 5
45 = 3 x 3 x 5
Form these factors we have to find the numbers which are common in all the three .
LCM = 2 x 3 x 3 x 3 x 5 = 270 .
Now 270 is completely divisible but the number which we want leaves 3 as remainder.
So adding 3 in 270 .
→ 273 is the required answer.

Find the longest side of a parallelogram with a perimeter of 66ft., If the sides measure 3x + 1 and 2x - 3.
Find the longest side of a parallelogram.
Formula used:-Perimeter of parallelogram = 2 ( a + b )
Solution:-We know that,
Perimeter of parallelogram = 2 ( a + b )
★ Substituting the values in the above formula,we get:
⇒ 66 = 2 ( 3x + 1 + 2x - 3 )
⇒ 66 = 2 ( 5x - 2 )
⇒ 66/2 = 5x - 2
⇒ 33 = 5x - 2
⇒ 5x - 2 = 33
⇒ 5x = 33 + 2
⇒ 5x = 35
⇒ x = 35/5
⇒ x = 7 ft
Now,
One side,a = 3x + 1
★ Putting the value of x
⇒ 3 × 7 + 1
⇒ 21 + 1
⇒ 22 ft
Other side,b = 2x - 3
★ Putting the value of x
⇒ 2 × 7 - 3
⇒ 14 - 3
⇒ 11 ft
Hence,the longest Side of given parallelogram is 22 ft ( 3x + 1 ) .
Brainlest to first correct answer1. Which of the following satisfy the requirements of a set? Explain why the
requirements are or are not met.
(a) All the current U.S. Senators from Texas
(b) All the prime divisors of 1987
(c) All the tall people in Mexico
(d) All the prime numbers between 8 and 10
Answer: The sets are:
b and d.
Step-by-step explanation:
A set is a collection of distinct objects, a set must be well defined, and it can contain numbers, people, objects, etc. (sets can contain infinite elements, for example, the set of the real numbers has infinite elements)
A) The current U.S senators from Texas.
Ok, the "current U.S senators from Texas" depend on when this is read. For example, the senators of today will not be the same as the senators in 10 years from now.
So the elements of this set today are not the same as the ones in 10 years, then this is not a well defined set.
A weel defined set in this case, would be:
"The U.S senators from Texas for the year 2020"
So this is a set of numbers, we know that 1987 is a prime number, so the only prime number that divides 1987 is 1987.
Then this set is {1987}
is well defined.
c) All the people in Mexico.
A person is well defined.
So when i say "all the people in Mexico has for now" we can find all those "elements" and make a set with them.
But the people in Mexico change, so the elements of this set actually depend on when this is read, so this is not well defined.
D) Al the prime numbers between 8 and 10.
Well, we do not have any prime number between 8 and 10, so this is an empty set:
{∅}

A wheelchair ramp is 4.2 meters long. it rises up 7.0 meters. what is the angle of elevation to the nearest tenth of a degree?
=======================================
Work Shown:
I'm assuming your teacher meant to say the ramp is 7 meters long and the ramp rises up 4.2 meters. It doesn't make sense the way they phrased it initially since the ramp must be the longest part (it is the hypotenuse of the right triangle).
See diagram below.
The angle of elevation is the angle made between the ramp and the ground. It's the angle amount the ramp tilts upward.
sin(angle) = opposite/hypotenuse
sin(theta) = 4.2/7
sin(theta) = 0.6
theta = arcsin(0.6)
theta = 36.869897645844
theta = 36.9
Note: inverse sine or [tex]\sin^{-1}[/tex] is the same as arcsine. Make sure your calculator is in degree mode.

T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released. The average rate of change in T(d) for the interval d = 4 and d = 10 is 0. Which statement must be true?
Options :
a. The same number of tickets was sold on the fourth day and tenth day.
b. No tickets were sold on the fourth day and tenth day.
c. Fewer tickets were sold on the fourth day than on the tenth day.
d. More tickets were sold on the fourth day than on the tenth day.
Answer:
a. The same number of tickets was sold on the fourth day and tenth day.
Step-by-step explanation:
Given that the average rate of change in T(d), a function used to relate the number of tickets sold for a movie to the number of days since its release is 0 for interval: d=4 and d=10.
Rate of change measures the change in quantity in relation to another, in the scenario it could be interpreted as, the change in quantity of ticket t sold with respect to change in the number of days since the movies was released.
Therefore, if the average rate of change obtained for d =4 and d = 10 gives 0, then it could be inferred that the value of T(d) on both days are the same.
[T(10) - T(4)] / 2 = 0
Then T(10) = T(4)

Tally Lake is 11.25 miles long. Mary starts at one end and kayaks toward the other end, paddling at a constant rate of 2.5 miles per hour. At the same time, Ann starts out from the opposite end and paddles toward Mary at a constant rate of 2 miles per hour. How long will it take for the girls to meet?
Answer:
2 and a half hours
Step-by-step explanation:
Hello!
To find this we add how far Mary and Ann travel and subtract that from the total distance till we get 0
2.5 + 2 = 4.5
11.25 - 4.5 = 6.75 First hour
6.75 - 4.5 = 2.25 Second hour
2.25 is half of 4.5 and half an hour is 30 minutes
2.25 -2.25 = 0 half hour
It will take them 2 and a half hours
The answer is 2 and a half hours

Amelia and Joey decided to shoot arrows at a simple target with a large outer ring and a smaller bull's-eye. Amelia went first and landed 3 arrows in the outer ring and 3 arrows in the bull's-eye, for a total of 267 points. Joey went second and got 4 arrows in the outer ring and 3 arrows in the bull's-eye, earning a total of 281 points. How many points is each region of the target worth? The outer ring is worth ____ points, and the bull's-eye is worth ____ points.
Answer:
outer ring worth 14 pts
bull's-eye worth 74.333333 pts
Step-by-step explanation:
let the worth point of landing an arrow on the outer ring be "x" and on bull's eye be "y"
For amelia
[tex]3x + 3y = 267[/tex]
For joey
[tex]4x + 3y = 281[/tex]
subtracting the first equation from the second
