After 3 months memberships will cost the same.
We have,
Cost of Membership of 1st gym = $ 10 per month
And, the Cost of the sign-up fee for 1st gym = $ 45
And,
Cost of Membership of 2nd gym = $ 25 per month
And, the Cost of the sign-up fee of the 2nd gym = $ 0
Now,
Let the number of months = m
So,
According to the question;
45 + 10m = 25m
⇒
25m - 10m = 45
15m = 45
m=3
So, After 3 months memberships will cost the same.

Solve for the value of x:-
4x+3(x-1)=67
Answer:
x = 10
Step-by-step explanation:
4x + 3(x - 1) = 67 ← distribute parenthesis and simplify left side
4x + 3x - 3 = 67
7x - 3 = 67 ( add 3 to both sides )
7x = 70 ( divide both sides by 7 )

Venn diagram ( attached image )
Assessing the given Venn diagram and the data related to it, we can answer the required question:
Q1. How many people were surveyed = 86.
Q2. What is the probability that a customer chosen at random:
a) takes salt P(S) = 46/85.
b) takes both salt and vinegar P(S ∩ V) = 13/85.
c) takes salt or vinegar or both P(S ∪ V) = 66/85.
The number of people who take salt chips n(S) = 46.
The number of people who take vinegar chips n(V) = 33.
The number of people who takes both n(S ∩ V) = 13.
The number of people who take neither n((S ∪ V)') = 19.
Therefore, the total number of people surveyed n(U) = n(S) + n(V) - n(S ∩ V) + n((S ∪ V)') = 46 + 33 - 13 + 19 = 85.
The number of people who takes salt or vinegar or both n(S ∪ V) = n(U) - n((S ∪ V)') = 85 - 19 = 66.
The probability that a customer chosen at random takes salt P(S) = n(S)/n(U) = 46/85.
The probability that a customer chosen at random takes both salt and vinegar P(S ∩ V) = n(S ∩ V)/n(U) = 13/85.
The probability that a customer chosen at random takes salt or vinegar or both P(S ∪ V) = n(S ∪ V)/n(U) = 66/85.

In a school, the number of girls is 70 more than boys. the total number of students is 1280. find the number of girls and boys simple equations
Answer:
Boys = 605
Girls = 675
Step-by-step explanation:
Let x be the number of boys in school.
So, girls = (x+70)
Total no. of students = 1280
x + x + 70 = 1280
2x + 70 = 1280
2x = 1280 - 70
2x = 1210
x = 1210/2
x = 605
Hence, no. of boys = 605
no. of girls = 605 + 70 = 675

O A. Maximum at (-6, 6)
OB. Maximum at (6, 6)
OC. Minimum at (-6, 6)
OD. Minimum at (6, 6)
Answer:
A
Step-by-step explanation:
Since x has a negative coefficient, the graph opens downwards meaning that it has a maximum.
The vertex formula is y = a(x - h)^2 + k so the coordinate must be (-6, 6).

Who is correct? In words explain why.
Joe is correct as the unknown number is 6.
What are exponents?The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.
Given :
[tex](x^2)^?=x^4\times x^8[/tex]
Let the question mark exponent outside the bracket be y, which needs to be determined
[tex](x^2)^y=x^4\times x^8[/tex]
Simplify the equation by applying exponent rules to either side of the equation:
Apply the rule [tex](a^b)^c = a^{b \times c}[/tex]
[tex](x^2)^y=x^4\times x^8[/tex]
[tex](x)^{2y}=x^4\times x^8[/tex]
Now apply [tex]a^b \times a^c = a^{b+c}[/tex]
[tex](x)^{2y}=x^{4+8}\\\\(x)^{2y}=x^{12}[/tex]
So, the base is the same the exponent will be the same also,
2y = 12
y = 6
Hence, Joe is correct as the unknown number is 6.

775 tickets were sold for a game for a total of $1,587.50. If adult tickets sold for $2.50 and childrens tickets sold for $1.50,how many of each kind of tickets were sold?
350 tickets sold of children and 425 tickets sold for adult.
What is algebra?Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.
Let x be the number of adult tickets that were sold and y be the number of children's tickets that were sold.
Total 775 tickets were sold for the game.
So,
x + y = 775
If adults tickets sold for 2.50 and children's tickets sold for 1.50 and all the tickets were sold for a total of 1587.5, it means that
2.5x + 1.5y = 1587.5
put x = 775 - y
2.5(775 - y) + 1.5y = 1587.5
1937.5 - 2.5y + 1.5y = 1587.5
-y = 1587.5- 1937.5
y = 350
and, x = 775 - y = 775 - 350
x = 425

Find the nature of the graph of the function y = -9x3 + 5x2 - 2x using end behavior.
The graph goes upwards on the left side and downwards on the right side, so the correct option is the first one.
How is the end behavior of the function?
We have the function:
[tex]y = -9*x^3 + 5*x^2 -2x[/tex]
This is a cubic polynomial with a negative leading coefficient.
So, when x takes large negative values, because the leading coefficient is negative, y will take large positive values.
And when x takes large positive values, because the leading coefficient is negative, y will take large negative values.

A bakery has a sale on cookies. If a customer buys a dozen cookies for $15, each additional single cookie is $0.75. What is an equation that shows how the total cost depends on the number of single cookies purchased? (Assume that the order starts with a dozen cookies.) How much would a dozen cookies plus six single cookies cost?
Answer:
T = 15 + 0.75c
T = $19.5
Step-by-step explanation:
Assume that T stands for total cost and c stands for number of single cookies purchased, the equation would be:
T = 15 + 0.75c
Therefore, a dozen cookies plus six single cookies would cost:
T = 15 + 0.75(6)
T = 15 + 4.5
T = $19.5
