452 because you will multiply 80 by 6 and get 480 and subtract 28 from that!
Answer:
83%
Step-by-step explanation:
AP.EX :)
This should be easy because we just have to use substitution method. Substitute the value of x from the second equation into the x of the first equation.
-4(2y) + 11y = 15
-8y + 11y = 15
3y = 15 ; y = 5
Substitute this value of y to either the first or second equation.
x = 2(5) = 10
The ordered pair is therefore (10,5).
48 develop a fault out of the total built which is 2400 therefore
48/2400
If needs to be simplified then 1/50
