<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:
b
Step-by-step explanation:
b is the answer
the range is all real number
Since pi is irrational and it is used in the formula, we cannot give an exact answer except in terms of pi (we can give an aproxamation using 3.14 =aprox pi, but it is not exact)
ok
circumfernce=2pir
r=15
circumference=2pi15
circumference=30pi
exact=30pi cm
if you want to aprox pi=3.14 then
aprox circumfernce=94.2 cm
Answer:
78%
Step-by-step explanation:
Given the information, we can write:
P(cook) = 52%
P(shop) = 54%
P(cook and shop) = 28%
Now, we need to find P(cook or shop).
We need probability formula for general addition rule, which is:
P(A or B) = P(A) + P(B) - P(A and B)
We can take "cooking" and Event "A" and "shopping" as Event "B".
Thus, we write:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.52 + 0.54 - 0.28
P(A or B) = 0.78
Which is 78%
