Step-by-step explanation:
For question for you divide the number of slices, 176, by the number of loafs, 8. this give give you a total of 22. you then take 22 and multiple if by 5, leaving your answer to 110 slices of bread.
For question 5, you multiple 8 kilometers by 1.6 kilometers, which is 12.8 miles.
I hope this helps :))
first equation equivalent to
4x+8y=28
substract with second equation
-2x=22
divide with -2
x=-11
substitute to first equation
8y=28-4(-11)
8y=72
divide with 8
y=9
so the solution is (-11,9)
