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 for his tomato plants. How many kilograms of plant food did Sheldon have left? Which number sentence matches the problem? * 1 point

kg of plant food

Step-by-step explanation:

The second question doesn't have choices, so I'll answer the first question only.

In order to know how much plant food Sheldon has, you have to subtract kg of plant food used for the strawberry plants from kg of plant food. Then, kg will be subtracted from the difference.

Let's convert both fractions into improper fractions first, so it will be easier to subtract.

Now, let's subtract.

Next, you have to subtract kg of plant food used for the tomato plants from the remaining plant food of kg.

Let's subtract again.

Therefore, Sheldon has kg of plant food left.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
