The set of whole
Solve the following problem:
numbers is partitioned into subsets with the first
number in the first subset
, the next two numbers in the
second subset, and the next three numbers in the third
subset and so on. Find in terms of n, a formula for the
nth member of the nth subset.
. The thief and three guards in an orchard:
Three guards were protecting an orchard. A thief met​

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

idk

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

i dont know the answer but here's a picture of a dog
