On sunday, sheldon bought 4 1/2 kg of plant food. he used 1 2/3 kg on his strawberry plants and used 1/4 kg on his tomato plants. how many kilograms of plant food did sheldon have left?

The amount of plant food left after the complete utility is 65/4 kg

Given data:

The amount of plant food bought by Sheldon is, X = 41/2 kg.

Amount of plant food used for the strawberry plantation is, x= 12/3 kg.

Amount of plant food used for the tomato planation is, y = 1/4 kg.

Let z be the amount of plant food left after the complete utility. Then, the equation is given as,

z = X - x - y

Solving as,

Thus, we can conclude that the amount of plant food left after the complete utility is 65/4 kg.

Sheldon had 2 7/12 kg left

Step-by-step explanation:

4 1/4 - 1 2/3 = 3 1/4 - 2/3

                   = 3 3/12 - 8/12

                   = 2 15/12 - 8/12

                   = 2 7/12

Hope this helps! have an amazing day :)

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
