2a=14 how do you solve this equation?
Answer:
a=7
Step-by-step explanation:
step one: divide both sides by 2
now you will have [tex]a=\frac{14}{2}[/tex]
step two: divide 14 by 2
14/2 is 7 so a is equal to 7

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]

Find the equation of the line shown
Solve this equation for x:
-100+2х=80+бх
Answer:
-45
Step-by-step explanation:
-100 + -80 = 6x + -2x
-180 = 4x
-180/4 = -45
Answer:
x= -45
Step-by-step explanation:
-100 + 2x = 80 + 6x
-80 - 2x = -80 -2x
------------------------------
-180 + 0 = 0 + 4x
-180/4 = x
-45 = x
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

An event organizer found that 70% of young couples prefer to have indoor weddings instead of outdoor weddings. You want to survey three randomly chosen couples and use the results to find the estimated probability that all three couples prefer indoor weddings.
This scenario can be simulated by generating a set of three numbers using a number generator with numbers
. The numbers
would represent couples who prefer indoor weddings. If all three numbers in the set are in the range
, it would mean that all three couples prefer indoor weddings.
Answer:
1. 0-9
2. 0-6
3. 0-6
Step-by-step explanation:
This scenario can be simulated by generating a set of three numbers using a number generator with numbers 0-9. The numbers 0-6 would represent couples who prefer indoor weddings. If all three numbers in the set are in the range 0-6, it would mean that all three couples prefer indoor weddings.
(ik you might not need this anymore, but I'm hoping it proves useful to others)

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

Can anyo help me thanks
Answer:
(-3, -5)
Step-by-step explanation:
We will multiply (6a -2b = -8) by -3, and (a - 3b = 12) by 2
Thus,
-18a + 6b = 24
2a - 6b = 24
=
-16a = 48
a= -3
Then we'll substitute,
-18(-3) + 6b = 24
54 + 6b = 24
6b = -30
b = -5

Charlie is thinking about buying a game for his Xbox that cost $60 and requires a subscription to basic Xbox live that cost $10 per month he could choose to upgrade his Xbox live membership and then the game will be included but that membership is $15 a month how many months would Charlie have the game before the cost of the two is the same?
Answer:
by 12 months both prices will be 180.
Step-by-step explanation:
If you take 12 and multiply it by 10 because that is the monthly subscription, you will get 120 + 60 for the game which equals 180. But if you take 12 and multiply it by 15 you will also get 180.

Answer: B -4
Step-by-step explanation:
Value of coefficient of the squared term in the parabola's equation = -4
Correct option is B.
What is parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.
Given,
Vertex of parabola (h,k) = (3, 5)
y = 6 for x = -1
Parabola opens horizontally left side
Vertex-form equation of parabola
x = a(y - k)² + h
-1 = a(6 - 5)² + 3
-1 = a(1) 3

Jonathan is making his favorite pasta dish. He serves his mom 1/12 of the pot of pasta and his brother 1/6 of the pot. How much of the pot is left over? PLS HELP I HATE MATH
Answer:
3/4 of the pot left.
Step-by-step explanation:
If the mom eats a 1/12 of the pot and then the brother also eats a 1/6 of the pot, then it is 9/12 left of pasta still. The reason for that is since 1/6 is equivalent to 2/12 so 1/12 plus 2/12 is 3/12, and if u subtract 3/12 from 12/12 it will give you 9/12 which can be simplified to 3/4 left of the pot.
Answer:
3/4 of the pot is left over
