therefore,
2x+12 = 3x - 22
2x = 3x -22 - 12
2x = 3x - 34
34 = 3x - 2x

Carlo wants to join the gym.The gym offers three membership options 1.Pat as you go. 2.All in one price. 3.Regular deal
Answer:
This question is incomplete and lacks essential data, I have found a similar question and I am putting data below to complete this question and will try to solve this.
1. $120 = Pay as you go
2. $90 = Regular Deal
3. $100 = All in one price.
For Carlo, regular deal is the best option to choose because he goes to gym 20 times and it is least expensive.
Step-by-step explanation:
This question is incomplete and lacks essential data, I have found a similar question and I am putting data below to complete this question and will try to solve this.
Question Complete: Carlo wants to join the gym. The gym offers three membership options
1.Pay as you go = Pay only $6 each time you work out
2.Regular deal = Pay $50 a month and $2 each time you work out
2.All in one price = Pay one time $100 per month for unlimited use of our great facilities.
Carlo thinks he will go to the gym about 20 times a month.
Calculate how much each of these options would cost Carlo for one month.
Solution:
Option 1. Pay as you go:
Each time gym fee = $6
Carlo thinks he will go to gym 20 times a month
So,
Cost for option 1 = $6 x 20 = $120
Option 2. Regular deal:
$50 a month + $2 each time
So, Carlo thinks he will go to gym 20 times a month
Cost for option 2 = $50 + 20x(2$) = $90
Similarly,
Option 3. All in one price:
Fee = one time $100 per month.
Cost for option 3 = $100 per month
Because there is not any each time visit fee in this option, so whether Carlo go to gym 20 times or 30 times a day. he will be charged a fixed fee of $100 a month.
For Carlo, regular deal is the best option to choose because he goes to gym 20 times and it is least expensive.
Satoshi started studying how the number of branches on his tree grows over time.
The relationship between the elapsed time t, in years, since Satoshi started studying the tree, and the
number of its branches, N(t), is modeled by the following function:
15
N(t) = 24 - 3
Complete the following sentence about the growth rate of the branches.
The number of branches triples every
years.
Answer:
The number of branches triples every 15 years.
Step-by-step explanation:
Satoshi started studying how the number of branches on his tree grows over time.
The relationship between the elapsed time t, in years, since Satoshi started studying the tree, and the number of its branches, N(t), is modeled by the following function:
N(t) = 24 - 3^t/15
Complete the following sentence about the growth rate of the branches. The number of branches triples every years.
The number of branches triples every 15 years.
What is a mathematical function, equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that the relationship between the elapsed time [t], in years, since Satoshi started studying the tree, and the number of its branches [N(t)], is modeled by the following function → N(t) = 24 - 3^t/15
The function that models the situation is -
N(t) = 24 - 3ⁿ/15 .... Eq[1]
After tripling the number of branches, we can write -
3N(t) = 24 - 3ⁿ/15
N(t) = {24 - 3ⁿ/15}/3 ..... Eq [2]
Equating both equations, we get -
{24 - 3ⁿ/15} = {24 - 3ⁿ/15}/3
3{24 - 3ⁿ/15} = {24 - 3ⁿ/15}
72 - 3ⁿ/5 = 24 - 3ⁿ/15
72 - 24 = 3ⁿ/5 - 3ⁿ/15
48 = 3ⁿ(1/5 - 1/15)
n = 15
Therefore, the number of branches triples every 15 years.

HELP FIND THE UNIT RATE OF 90 DAYS/20 TRIPS PLEASEEEEE
Answer:
The unit rate is 4.5 days per trip
Step-by-step explanation:
So the equation would be 90 divided by 20
Simplified it is the same thing as 9 divided by 2
90 divided by 20 is 4.5
Answer:
4.5/1
Step-by-step explanation:
First, I found that 10 was the first factor or whatever I could find, so our new ratio is:
9/2
This is obviously not the unit rate, but if we divide by 2 we get:
4.5/1
So our unit rate is 4.5/1

Work out the percentage change to 2 decimal places when a price of £125.99 is increased to £150.
Answer:
Percent change is 19.06%
Step-by-step explanation:
It is given that:
Price before change = £125.99
Price after increase = £150
Change = 150 - 125.99 = £24.01
Percent of change = [tex]\frac{Change}{Price\ before\ change}*100[/tex]
Percent of change = [tex]\frac{24.01}{125.99} * 100[/tex]
Percent of change = 0.1906 * 100
Percent of change = 19.06%
Therefore,
Percent change is 19.06%

What is the axis of symmetry for the graph of y = -2x + 16x - 7?
O x= -8
O x = 8
O x=-4
O x = 4
I need the answer
Answer:
The axis of symmetry for the graph of y = -2x² + 16x - 7 will be:
x = 4
Hence, the last option i.e. x = 4 is the correct option.
Step-by-step explanation:
Given the equation
[tex]y\:=\:-2x^2\:+\:16x\:-\:7[/tex]
For a parabola in standard form y = ax² + bx + c
The axis of symmetry is the vertical line that goes through the vertex x = -b/2a
so
The axis of symmetry for y = ax² + bx + c is x = -b/2a
In our case,
[tex]a=-2,\:b=16[/tex]
Therefore,
x = -16/2(-2)
x = -16 /-4
x = 16/4
x = 4
Therefore, the axis of symmetry for the graph of y = -2x² + 16x - 7 will be:
x = 4
Hence, the last option i.e. x = 4 is the correct option.

Answer:
BC is 40.8
B° is 59.03°
C° is 30.96°
Step-by-step explanation:
classic pythagoras (a² + b² = c²)
35² + 21² = 1666
sqrt1666 = 40.8
you do tan(x) here because you want to find B° and only know the opposite and adjacent sides.
35/21 = 1.66...
tan-¹(1.66..) = 59.03°
you do tan(x) here because you want to find C° and only know the opposite and adjacent sides.

what is 125% of 12.8
The required value of the given percentage is 16. "125%" represents 125 parts out of 100, which is equivalent to 1.25 times the original value.
To find 125% of 12.8, we can multiply 12.8 by 1.25.
First, we convert the percentage to decimal form by dividing it by 100. So, 125% becomes 1.25.
Next, we multiply 12.8 by 1.25:
12.8 × 1.25 = 16.
Therefore, 125% of 12.8 is 16.
Multiplying 12.8 by 1.25 increases it by 25% or adds one-quarter of the original value. Thus, the result of 16 represents an increase of 25% from 12.8.
Thus, the required value of the given percentage is 16.
