2/5 of 30 = 12
30 + 12 = 42
£42
Taking the same test right now....I think the answer is 4.5. Hope that helps!
Mallory purchased 8 oranges.
6*0,75+n*1,25=14,50
we need the graph/ lines,
but just remember
wherever 2 lines intersect, that is a solution
if they are paralell, no solutions
if they cross, 1 solution
if they are the same line/ the lines are on top of each other exactly, infinite solutions
I think the problem is work this way because y is equal to 72 and x is 3 you just multiply 72(3)2=432
