Angelina_Jolie [31]

Answer:

38 pages per hour

Step-by-step explanation:

Rate of reading = $\frac{\text{Total number of pages read by Davida}}{\text{Time taken to read}}$

By substituting the given values in the question,

Total number of pages read by Davida = $28\frac{1}{2}$ = $\frac{57}{2}$

Time taken by Davida = 45 minutes

Since, 1 minute = $\frac{1}{60}$ hours

Therefore, 45 minutes = $\frac{45}{60}=\frac{3}{4}$ hours

Rate of reading = $\frac{\frac{57}{2}}{\frac{3}{4} }$

= $\frac{57}{2}\times \frac{4}{3}$

= 38 pages per hour

Therefore, rate of reading by Davida is 38 pages per hour.

Consider the equation

muminat

Answer:

A. $a=10\\ \\b\neq -8$

B. $a=10\\ \\b= -8$

Step-by-step explanation:

Consider the equation

$2(5x-4) = ax + b$

A. This equation has no solutions when the coefficients at x are the same and the free coefficients are not the same.

First, use distributive property:

$2(5x-4)=2\cdot 5x-2\cdot 4=10x-8$

So, the equation is

$10x-8=ax+b$

This equation has no solutions when

$a=10\\ \\b\neq -8$

B. The equation has infinitely many solutions when the coefficients at x are the same and the free coefficients are the same too.

So, the equation

$10x-8=ax+b$

has infinitely many solutions when

$a=10\\ \\b= -8$

In other cases, the equation has a unique solution
