Answer:
85 cents
Step-by-step explanation:
Let a represent the price of pineapples
Let p represent the price of peaches
74p + 9a= 14p + 21a
p = 17 cents
Substitute 17 for p
74(17) + 9a = 14(17) + 21a
1258+9a= 238+21a
1258-238= 21a-9a
1020= 12a
a= 1020/12
a= 85
Hence the price of pineapples is 85 cents
Is the "x" a multiplication sign?
180 is the speed of the motorboat. I don't know the speed of the current.

120÷4=30
30×6=180
-8
On the number line if you are at positive 8 and add -8 you will lose 8 and get zero! Hope this helps!
-2a from both sides then divide by -5 and a=1
