Answer: X * 1 + Y * 3 + Z * 2 = 45
Step-by-step explanation: we will use bananas, apples and mangoes as the unknowns of the equation.
The value that you multiply to the unknowns will be multiplied by the price that corresponds to it.
These 3 products must be added to result in the total value that is 45.
X * 1 + Y * 3 + Z * 2 = 45
Your answer is X*1+Y*3+Z*2=45

Answer:
9
Step-by-step explanation:
You do 90 divided by ten.
it could be 2.2 because every 5 you get 2 so it would be 10 and 4 so when y=6 then x should be 2.2.
Cmon this is easy it is 24 okay
Answer:
10x-4 feet
Step-by-step explanation:
The perimeter is the amount of the sides together so add the three sides together
2x+1+4x-4+4x-1
Combine like terms
10x-4
(You can also factor out 2 but that would not be simplest --> 2(5x-2))
3 over 33 I believe if you don't have to simplify
