Answer:

A. x = -3

B. x = 2

C. x = 9/10

Step-by-step explanation:

(A) –12x + 9 = –15x

Collect like terms

9 = -15x + 12x

9 = -3x

x = 9 / -3

x = -3

(B) 4.5x + 11.5 = 8.5x + 3.5

4.5x - 8.5x = 3.5 - 11.5

-4x = -8

x = -8 / -4

x = 2

-9 = 13x - 23x

-9 = -10x

x = -9 / -10

x = 9/10

Answer:

greater than or equal $46$ to and less than $96$

Step-by-step explanation:

GIVEN: On the first four exam your grades are $76,78,73$ and $77$ . You are hoping to earn a C in the course. This will occur if the average of your fifth exam grades is greater than or equal to $70$ and less than $80$ .

TO FIND: range of grades on the fifth exam will result in earning a C.

SOLUTION:

Total number of marks scored till first four exams $=76+78+73+77$

$=304$

let average marks scored after fifth exam be $S$ .

let marks scored in fifth exam be $x$

$S=\frac{76+78+73+77+x}{5}$

$S=\frac{304+x}{5}$

Now, to earn a C the average must be greater than or equal to $70$ and less than $80$

$70\leq S< 80$

$70\leq \frac{304+x}{5}$

when

$\frac{304+x}{5}\geq 70$

$304+x\geq 350$

$x\geq 46$

when

$\frac{304+x}{5}$

$304+x$

$x$

Hence grades in fifth exam must be greater than or equal $46$ to and less than $96$
