There are 12 groups with 4 students and 3 groups with 5 students
How many groups will have 4 students, and how many will have 5?Represent the students as follows:
Group with 4 students = x
Group with 5 students = y
So, we have the following system of equations
4x + 5y = 63
x + y = 15
Make x the subject in x + y = 15
x = 15 - y
Substitute x = 15 - y in 4x + 5y = 63
4(15 - y) + 5y = 63
Expand
60 - 4y + 5y = 63
Evaluate
y = 3
Substitute y = 3 in x = 15 - y
x = 15 - 3
This gives
x = 12
Hence, there are 12 groups with 4 students and 3 groups with 5 students

98,615 kg of sugar was produced in the year 1993.This was 75069 kg more than the quantity of sugar
produced in 1992.What was the production in 1992 ?
173,684 was the production in 1992 in a linear equation .
What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5. When an equation is given in this format, finding both intercepts is rather simple (x and y).the production in 1992 = 75069 × 1 + 98,615
= 75069 + 98,615
= 173,684

Find the 96th term of the arithmetic
sequence -3, -14, -25,
The 96th term of this arithmetic sequence is -1059.
In an Arithmetic Progression (AP), the nth term is given by the formula-
a9 = a + (n-1)d
where a = first term of the AP
d = common difference
Here, we are given an AP-
-3, -14, -25
Here a = -3
and d = -14 + 3 = -11
Let the 96th term of the AP be a96
Therefore, according to the formula for finding the nth term of an AP, we get-
a96 = a + (96-1)d
a9 = a + 95d
Substituting the values of a and d given in the question-
a96 = -3 + 96(-11)
a96 = -3 - 1056
a96 = -1059
Thus, the 96th term of the arithmetic sequence is -1059.

Three times the sum of a number and two is equal to -9.
The graph of the function f is shown. The domain of f is [0, 50]. What is the range of g(x) = 4f(x)?
The graphs with the X-coordinate marks 0, 10, 20, 30, 40 and 50. The Y-coordinate mark 0, 0.5, 1, and 1.5. There is an absolute value function with vertex at (25, 1.75). It starts at origin and ends at (50, 0).
A. [0, 50]
B. [0, 70]
C. [0, 1.75]
D. [0, 7]
Based on the calculations using the given graph, the range of g(x) is equal to: D. [0, 7].
How to identify the range and domain of this graph?The vertical extent of a graph represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.
Similarly, the horizontal extent of a graph represents all domain values and they are also read and written from smaller to larger numerical values, and from the left of the graph to the right.
By critically observing the graph of f(x) shown, we can infer and logically deduce the following:
Domain = (0, 50) i.e the domain is all real numbers.
Range = (0, 1.75).
What is the range of g(x) = 4f(x)?At the minimum f(x) = 0, we have:
g(x) = 4 × 0
g(x) = 0.
At the maximum f(x) = 1.75, we have:
g(x) = 4 × 1.75
g(x) = 7.
Therefore, the range of g(x) is equal to [0, 7].

A local gym is running a promotional offer of 40% off their annual gym memberships.
The annual membership costs £340.
How much discount would you get off?
What is the cost of the membership after the discount?
The cost of the membership after a discount of $ 136 will be $ 204.
We are given that:
a local gym is giving a discount for the promotional offer it has to make.
Discount percentage = 40 %
Cost of the annual membership = $ 340
Discount = 40 % of $ 340
Discount = 40 / 100 × $ 340
Discount = 0.4 × $ 340
Discount = $ 136
So, the cost of annual membership after discount will be:
Cost = $ 340 - $ 136
Cost = $ 204
Therefore, the cost of the membership after a discount of $ 136 will be $ 204.
