9x = -2
x = -2/9
Answer:
A store sells bread and milk. On Tuesday, 3 loaves of bread and 2 litres of milk were sold for €6.25. On Thursday 4 loaves of bread and 5 litres of milk were sold for €10.90. If b = the price of a loaf of bread and m = the price of
one litre of milk, Tuesday's sales can be written as 3b+2m=6.25.
Part A Using simplest terms, write an equation in band m for Thursday's sales.
PartB calculate the values of b and m
3b + 2m= 6.25 >> Tuesday equation 1
4b + 5m = 10.90 >> Thursday equation 2
Subtract equation 1 and 2
3b+2m-6.25-4b+5m-10.90= 0
b+7m-4.65= 0
b+7m= 4.65+0
b+7m= 4.65
b= 4.65 - 7m
if b= 4.65-7m
then substitute b in b+7m=4.65
4.65-7m+7m= 4.65
4.65-m= 4.65
4.65-4.65= m
m= 0

Answer:
B. 11/18
Step-by-step explanation:
Solve using algebra.
x = 0.611111...
10x = 6.111111...
10x - x = 6.111111.. - 0.61111111..
9x = 5.5
x = 5.5/9
x = 11/18
