Evaluate the given expression if x= -3 and y=6.

x+3y / 6+3y

5/8

Step-by-step explanation:

The given expression is

We need to find of above expression when x = -3 and y = 6

Put x = -3 and y = 6 in given expression such that,

So, the value of given expression is 5/8.

d

step-by-step explanation:

i used the pitagoras theoreme

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
