Marco needs to buy some dog food. At the nearest store, 6 bags of dog food cost $31.50. How much would Marco spend on 5 bags of dog food.

your answer would be $13.50 because is 3 bags cost 6.75 and you need 6 bags then just multiply the 6.75 by 2 and you get your answer :)

Step-by-step explanation:

Marco would spend $26.25 on 5 bags of dog food.

Step-by-step explanation:

1. You have to find out how much each bag costs, so you need to divide. You divide the cost of dog food by the number of bags of dog food.

                                     31.50 ÷6= 5.25

So 1 bag of dog food costs $5.25.

2. To find out how much 5 bags of dog food costs, you multiply 5.25 by 5.

                                    5.25x5=26.25

5 bags of dog food costs $26.25.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

it would be 9 because when it is the nine is over five so that would mean it rounds up to 90 or 9
