Taylor earns $5 each time she walks her neighbor's dog.she has already earned $25.write and solve an equation to find out how many more times taylor needs to walk the dog to earn enough to buy a bike that cost $83.
Answer:
Equation: $83=5w+25 and 12 walks more
Step-by-step explanation:
Here is an equation: $83=5w+25
The $83 on the left represents the $83 goal for the bike (or the total amount of money that Taylor needs)
The 5w represents that Taylor earns $5 per time she walks the dog, with the w being the number of walks.
The +25 shows that Taylor has already earned $25 from walking the dog. (Not sure if you need it, but the $25 took 5 dog walks –– 5•5=25)
To solve:
83 = 5w + 25 –– Subtract 25 from both sides to get the variable term alone
58 = 5w –– Divide both sides by 5 to get w alone
11.6 = w –– Round this up to 12 because you can't really do 3/5 of a walk (this means Taylor needs to walk the dog 12 more times to earn enough to buy the bike)
Check:
83=5w+25 –– Replace w with 12
83=5(12)+25 –– Multiply
83=60+25 –– Add
83=85 –– This shows she will have $2 left over

Answer:
x > 1
Step-by-step explanation:
Subtract 3 from both sides
8x + 3 - 3 > x + 10 - 3
Simplify
8x > x + 7
Subtract x from both sides
8x - x > x + 7 - x
Simplify
7x - 7
Divide both sides by 7

Mark was thinking of a number mark halves the number and gets an answer of 53.2 form an equations with x from the information
Answer: The number is 106.4
Step-by-step explanation:
Let the number be x
Mar halves the number becomes = x x 1/2 to get 53.2
The equation to solve this problem is x/ 2 = 53.2
Such that to find x
x/2= 53.2
x = 2 x 53.2= 106.4
The number is 106.4
An online shopping club has 13000 members when it charges $7 per month for membership. For each $ monthly increase in membership fee, the club loses approximately 500 of its existing members. Write and simplify a function R to represent the monthly revenue received by the club when x represents the price increase.
Hint: Monthly revenue = # members•monthly fee
Just a answer with work will do, ill brainliest the best one.
Answer:
The function is: [tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]
Step-by-step explanation:
Total members=13000
Membership charge per month=$7
Increase in Membership charge per month=$1
For each $1 monthly increase in membership fee, the club loses approximately=500 members
For 1 month, 1 dollar decrease is 500 × 1
For x months, the decrease in the members is 500 × [tex]x[/tex] =[tex]500x[/tex]
The increase in membership fee is 7 + [tex]x[/tex]
After that,
Monthly revenue = Number of members × Monthly fee
Monthly revenue = [tex](13000-500x)[/tex] × [tex](7 + x)[/tex]
[tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]

Brian, Josh, Chad, Jordan, Ryan, and Rachel are the 6 players in a round-robin racquetballtournament. Each player will play aset against each of the other players. List all the sets that need to be played.
there are 15 sets that need to be played in the tournament. To list all the sets, we can simply list all the possible combinations of 2 players from the group of 6.
What is the combination?
In simple words, combination involves the selection of objects or things out of a larger group where order doesn't matter. The formula for combination helps to find the number of possible combinations that can be obtained by taking a subset of items from a larger set.
There are a total of 6 players in the round-robin racquetball tournament, which means that each player will play a set against each of the other 5 players.
To determine the total number of sets that need to be played, we can use the combination formula:
nC₂ = (n*(n-1))/2
where n is the number of players.
In this case, n = 6, so:
6C₂ = (6*(6-1))/2 = 15
Hence, there are 15 sets that need to be played in the tournament. To list all the sets, we can simply list all the possible combinations of 2 players from the group of 6:

The radius of a circle is 3 m. Find its circumference in terms of pi
Gotcha, bro.
(I don't know what pi is, so I'm gonna assume that it is 3.14)
C=pi x diameter
First, multiply the radius by 2 so you have the diameter.
3x2=6
Second, multiply 3.14 (pi) by 6 (diameter)
3.14x6=18.84
Therefore, the circumference is 18.84.
(19 if you round it to the whole number)
Hope this helps!

The circumference of the circle is 6π meters.
What is a circle?A circle is a two dimensional figure with a radius and circumference of 2πr.
We have,
The circumference of a circle is given by the formula:
C = 2πr
where r is the circle's radius and π (pi) is a mathematical constant approximately equal to 3.14.
In this case, the radius of the circle is 3 meters.
Substituting this value in the formula, we get:
C = 2πr
C = 2π(3)
C = 6π
Therefore,
The circumference of the circle is 6π meters.

A 9-foot ladder leans against a building six feet above the ground. At what height would a 15-foot ladder touch the building if both ladders form the same angle with the ground?
Answer:
10
Step-by-step explanation:
You make a proportion 9/6=15/x then multiply 6 and 15 and divide it by 9
The height the 15 ft building touches the building is approximately 10 ft.
The ladder is 9 ft tall and leaning on a wall that is 6 ft above the ground.
The situation forms a right angle triangle.
Properties of a right angle triangle:One of it angle is equals to 90 degrees.The sides and angles can be found using trigonometric ratios.Therefore, let's find the angle made by the 9 ft ladder and then use it to find the height the 15 ft ladder touch the building.
Using trigonometric ratios,
let
∅ = angle
tan ∅ = opposite / adjacent
tan ∅ = 6 / 9 = 2 / 3
∅ = tan⁻¹ 0.6666666
∅ = 33.6900672615
Therefore, the height the 15 ft ladder touch building can be calculated as follows:
tan 33.69 = h / 15
h = 15 × 0.66666496431
h = 9.99997446476
h ≈ 10 ft.
