Mona wrote 7 tests, and her test average is 93. There will be one more test before the end of the year. What is the lowest grade
olga55 [171]
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:
 \frac{93 + x}{2}  \geq  90
 From here, we clear the value of x: 93 + x  \geq  90*(2) 

93 + x  \geq  180

 x  \geq  180 - 93

 x  \geq  87
 Answer:
 
the lowest grade that Mona can get for her last test so that her test average is 90 or more is:
 
x = 87

Evaluate the expression for the given value of the variable. | − 4 b − 8 | + ∣ ∣ − 1 − b 2 ∣ ∣ + 2 b 3 ; b = − 2
Nastasia [14]

Answer:

-11

Step-by-step explanation:

The given expression is:

|-4b-8|+|-1-b^2|+2b^3

=|-(4b+8)|+|-(1+b^2)|+2b^3

=4b+8+1+b^2+2b^3

=4b+9+b^2+2b^3

Substituting the value of b=-2 in above expression, we get

=4(-2)+9+(-2)^2+2(-2)^3

=-8+9+4-16

=-11

Thus, the value of the given expression is -11.
