For this case, the first thing we are going to do is assume that all the tests are worth the same.
Then, we define a variable:
x: score of Mona's last test
We write now the inequality that models the problem:
From here, we clear the value of x:
Answer:
the lowest grade that Mona can get for her last test so that her test average is 90 or more is:
x = 87
Answer:
A
Step-by-step explanation:
Given that : g(x) = 4x + 4 .
So , in order to find the value of g(4) , just substitute x = 4 in the given function .
Here ,
=> g(x) = 4x + 4 .
=> g(4) = 4 × 4 + 4 .
=> g(4) = 16 + 4 .
=> g(4) = 20 .

Answer:
Step-by-step explanation:
Alright, lets get started.
The given equation is :
taking log on both side
Plugging the value of ln e as 1
Subtracting 6 in both sides
Dividing 3 in both sides

Answer:
3.8; 4
Step-by-step explanation:
In this exercise, you're are required to find the missing values by performing some arithmetic calculations.
<u>For the first part;</u>
Let the missing value be X
Translating the word problem into an algebraic expression, we have;
<u>For the second part;</u>
Let the missing value be Y.
Therefore, the complete sentence would be written as follows;
is 2000 times greater than 
. It is also 4 times greater than
