What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the equations are 2x - 2y = 12 and -8x -y = -15. The value of x and y will be calculated as,
2x - 2y = 12
-8x - y = -15
Solve the above equation,
2x - 2(-8x + 15) = 12
2x + 16x - 30 = 12
18x = 42
x = 42 / 18
x = 7 / 3
The value of y is calculated as,
-8x - y = -15
y = ( -8 x 7 / 3 ) +15

Given that the number of men is now 60% of the total members, how many of the 50 new members were women is to be determined,
Percentage of women, in the team = 100 - 60 = 40%
40% of total members are women = 35 + 50
Total members = 85 / 40%
Total member = 212
Number of new member that are boys = 212 - 85 - 65 = 62 boys

Jim has to choose between two gym membership plans. Plan A: $50 monthly membership fee and $10 per visit. Plan B: $25 one time membership fee and $15 per visit. How many visits must Jim make to make Plan A the cheaper option?
How many visits for them to cost the same?
The same cost of both of the plan of the gym will be in 5 visits. And plan B is better than Plan A as B is cheaper than A.
What is an expression?In mathematics, expression is the combining of variables with the application of operations and prescribed rules. It could take the shape of an equation, some numbers, etc.
We have,
plan A consists of :
Amount for monthly membership fee = $50
Cost per visit = $10
The expression of total fees would be:
50+10x,
where x is the number of times Jim visits the gym.
Plan B consists of :
Amount for monthly one time membership fee = $25
Cost per visit = 15
The expression of total fees would be:
25 + 15x,
where x is the number of times Jim visits the gym.
Here, x denotes the number of visits.
Let us suppose x = 1
Then, fees for plan A would be:
50 + 10 x1 = $60
Fees for plan B would be:
25 + 15 x1 = $40
To find the same cost in x number of visits:
We equate both the expressions.
50+10x = 25 + 15x
15x - 10x = 50 - 25
5x = 25
x = 5
That means, if Jim visits 5 times, the gym, then he would have the similar cost for both of the plans.
Hence, Plan B is better than Plan A as B is cheaper than A. The same cost of both of the gym will be in 5 visits.

A 41-year old woman has $398,100.00 in an IRA account. Due to medical concerns of a family member, she decided to make no additional contributions to the account but expect it to grow at 8% compounded every 4 months. How much does she expect to have in the account when she retires at age 65?
She expects to have $2710591.78 when she retires at age 65 with the principal amount is 398100, the interest rate is 8%, time period is 24 and number of times interest applied is 3 by the concept of compound interest.
What is compound interest?Interest that is paid on the principal and interest at regular periods is known as compound interest. The interest is calculated for the new principal at regular intervals after the interest that has already accumulated has been combined with the existing principal amount. The initial principal plus the interest that has accrued thus far are added together to form the new principal.
Interest on the principal + periodic compound = compound interest.
According to the question the principal amount is 398100, the interest rate is 8%, time period is 24 and number of times interest applied is 3.
Here the interest is compounded every 4 months
So, the formula of compound interest is as follows:
A=p (1+ [tex]\frac{r}{n}[/tex]) ∧ (n× t)
Where P is the principal balance, r is the interest rate, n is the number of times interest is compounded per year and t is the number of years.
Here the interest is compounded every 4 months hence the value of n is 12/4 which is equal too 3.
Insert the values of p, n, t, r in above equation,
A=398100(1+[tex]\frac{8}{300}[/tex]) ∧ (3×24)
A=398100× (1.027) ∧ (72)
A=398100×6.809

what is perimeter of rectangle ?perimeter of rectangle = 2(length + width)
length and width of the Luis plot by L and W, respectively.
We know that the perimeter, is 60 meters. So we can write:
2L + 2W = 60
Simplifying this equation, we can divide both sides by 2:
L + W = 30
now , area of the plot is 216 square meters:
L x W = 216
use substitution to solve for one of the variables. Let's solve for L in the first equation:
L = 30 - W
We can substitute this expression for L into the second equation:
(30 - W) x W = 216
[tex]W^2 - 30W + 216 = 0[/tex]
We can solve this quadratic equation using the quadratic formula:
W = [30 ± [tex]\sqrt{30^2 - 4 * 1 * 216}[/tex] / 2
Simplifying:
W = [30 ± 6] / 2
So W = 18 or W = 12.
If W = 18, then L = 30 - 18 = 12.
If W = 12, then L = 30 - 12 = 18.

f(x) = -7x + 42 if x > 5
How to express the function graphed?On the graph we can see a piecewise function (piecewise means that it has different equations defined for different intervals in the domain).
On the left side, we can see a linear equation that comes from negative infinity and ends at x = 2 with an open circle (so the domain does not contain that value).
That line passes through (-1, 0) and (0, 1), then the slope is:
a = (1 - 0)/(0 -(-1)) = 1
And the y-intercept is y = 1, then the equation of the line is:
y = x + 1
The other line starts at x = 5 (again, open circle) and keeps going, it passes through the points (5, 7) and (6, 0)
The slope is:
a = (0 - 7)/(6 -5) = -7
Then the line is something like:
y = -7*x + b
To find b, we use the point (6, 0)
0 = -7*6 + b
7*6 = 42 = b

What is meant by triangle?Triangles are polygons because they have three vertices and three edges. This is one of the basic shapes in geometry.
In Euclidean geometry, any three non-collinear points determine a distinct triangle and a distinct plane (i.e. a two-dimensional Euclidean space). To put it another way, every triangle has a plane that it is contained in, and there is only one plane that contains every triangle.

In how many ways can the digits in the number 7,400,000 be arranged?
Let a, b, c, d, e, f be integers selected from the set {1, 2, . . . , 100}, uniformly and at random with
replacement. Set
M = a + 2b + 4c + 8d + 16e + 32f.
What is the expected value of the remainder when M is divided by 64?
So the expected value of the remainder when M is divided by 64 is approximately 0.2080.
To find the expected value of the remainder when M is divided by 64, we can find the probability that M is congruent to each possible remainder modulo 64 and then sum these probabilities multiplied by the corresponding remainders.
For a positive integer n, let P(n) denote the probability that a positive integer chosen from the set {1, 2, . . . , 100} is congruent to n modulo 64. Then
P(0) = P(64) = P(128) = ... = 1/100
P(1) = P(65) = P(129) = ... = 1/100
P(63) = P(127) = P(191) = ... = 1/100
Since the integers a, b, c, d, e, and f are chosen independently and uniformly at random from the set {1, 2, . . . , 100}, the probability that M is congruent to n modulo 64 is P(n)^6.
Therefore, the expected value of the remainder when M is divided by 64 is
E = 0 * P(0)^6 + 1 * P(1)^6 + 2 * P(2)^6 + ... + 63 * P(63)^6
= (0^6 + 1^6 + 2^6 + ... + 63^6) * P(0)^6
= (0 + 1 + 2 + ... + 63) * P(0)^6
= 2080 * (1/100)^6
= 0.2080

For a positive integer n, let P(n) denote the probability that a positive integer chosen from the set {1, 2, . . . , 100} is congruent to n modulo 64. Then
P(0) = P(64) = P(128) = ... = 1/100
P(1) = P(65) = P(129) = ... = 1/100
P(63) = P(127) = P(191) = ... = 1/100
Since the integers a, b, c, d, e, and f are chosen independently and uniformly at random from the set {1, 2, . . . , 100}, the probability that M is congruent to n modulo 64 is P(n)^6.
Therefore, the expected value of the remainder when M is divided by 64 is
E = 0 * P(0)^6 + 1 * P(1)^6 + 2 * P(2)^6 + ... + 63 * P(63)^6
= (0^6 + 1^6 + 2^6 + ... + 63^6) * P(0)^6
= (0 + 1 + 2 + ... + 63) * P(0)^6
= 2080 * (1/100)^6
= 0.2080

Also,
Cookies sold by Miley in 30 minutes = 12 boxes.
To find the total boxes of cookies sold by girls in one hour,
Use ratio method,
Cookies sold by Kate in 3/4 hours = 27 boxes,
Cookies sold by Kate in 1 hour = 27 x (4/3) = 36
Cookies sold by Miley in 1/2 hours = 12 boxes,
Cookies sold by Miley in 1 hour = 12 x 2 = 24 boxes
Total cookies sold by Kate in Miley in one hour = 36 + 24 = 60
