Mr. martin’s yard is 1 1/3 acres. he wants to plant grass on 1/6 of his yard. how many acres will be covered by grass?

acres will be covered by grass.

Step-by-step explanation:

Mr. Martin's yard is 1 acres.

He wants to plant grass on of his yard.

To find the number of acres that will be covered by grass,

We multiply    by  1

i.e × = acres

if x decreases by 4 then y increases by 10

step-by-step explanation:

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.
