The rate at which the college student earns credit is 13 credits per semester.
<h3>What is an equation?</h3>
An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario.
Let the credit earned each semester be x.
This will be illustrated as:
5 + 2x = 31
Collect like terms
2x = 31 - 5
2x = 26
Divide
x = 26/2
x = 13
The rate is 13 credits per semester.

Answer:
Beena = 19 years old
Seema = 28 years old
Step-by-step explanation:
Beena = x
Seema = x + 9
x + 9 + 10 = 2x
19 + x = 2x
2x - x = 19
x = 19
surface area = 2 x pi x r x h + 2 x pi x r^2
2 x (3.14) x 1 x 12 = 75.36
2 x (3.14) x 1^2 = 6.28
75.36+6.28 = 81.64
if you cant use a fraction or decimal, does the answer need to be in terms of pi?
that would be 2 x PI x r x h = 2 x pi x 1 x 12 = 24PI
2 x PI x r^1 = 2 x PI x 1 = 2PI
24 PI x 2 PI = 26 PI
The value of k is
<h3>How to solve the simultaneous equation?</h3>
Given:
x-y=k.............(eq i)
2x²+y²-15..............(eq ii)
We would make y the subject formula in eq ii
2x²+y²-15= 0
2x² + y²= 15
y²= 15-2x²
y= ...........(eq iii)
Substitute the value of y into eq i
x-(= k
x- (= k
k=
