Answer:6.2
Step-by-step explanation:10-1/2-1/5-1/10=6.2
The answer for your answer is (x+3)(2x+7)
Let x be the number of new laptops and y be the number of tablets that the company should buy. The equations that best show the given conditions are as follows,
x + y = 30
515x + 285y = 11080
Solving simultaneously for the values of x and y gives an answer of x = 11 and y = 19.
Thus, the business should buy 11 laptops and 19 tablets.
Answer:

Step-by-step explanation:
Let the equation be : 
The point (1,1) must satisfy this equation.

Similarly, the point (1,3) must satisfy:

Also for the point (9,2), we have:

Solving the equations (1), (2) and (3) simultaneously, we get:

We Substitute this values to get:


Multiply through by 8 to get:

You can use times the value by 1.05 to find the answer directly
