Answer:
A)An expression to show the number of apples that Martin & Omar used in all is [tex]\frac{3}{2}x-5[/tex]
B)Martin could not have 10 apples
Step-by-step explanation:
Let x be the no. of apples used by Martin
We are given that Omar used 5 fewer than half as many apple as Martin used.
No. of apples used by Omar = [tex]\frac{1}{2}x-5[/tex]
Total apples used by both =[tex]x+\frac{1}{2}x-5=\frac{3}{2}x-5[/tex]
A ) So, an expression to show the number of apples that Martin & Omar used in all is [tex]\frac{3}{2}x-5[/tex]
B) Could Martin have used 10 apples
It Martin used 10 apples
So, x = 10
So, No. of apples used by Omar =[tex]\frac{1}{2}(10)-5=0[/tex]
So, No. of apples used by Omar is 0 which is not possible since we are given that Omar used apples to make sauce
So, Martin could not have 10 apples
