The answer to this question would be:
f(x) = 7 + 0.3x
Because 2 pounds will cost you $7, the $7 is required. If x is the number of ounces over 2 points and each ounce is 30 cents, it would only seem reasonable to multiply the ounces by 30 cents, right? Right. Therefore you add the 0.3x and you come towards the correct answer.
Answer:
Step-by-step explanation: 20x+15(160-x)=2625
20x+2400-15x=2625
5x=225
x=45
160-x=115
rate of first mechanic= $45/hr
rate of second mechanic=$115/hr
This is a false statement.
(8*4)xy/ (8*3)yz= 4x/3z
Break apart the each expression to its simpler parts. The 8s cross each other out and you have 4xy/3yz left. Then you cancel the variables that match. The only ones are the ys. Hence the answer is what you have left over and cannot cancel out or reduce
