Xiumin, Yuemei and Zavier have different numbers of pencils. The ratio of the number of Xiumin's pencils to the number of Yuemer's pencils is 3:2. After Xiurnin and Yuemei each give half of their pencils to Zavier, the number of Zavier's pencils increases by 50%. Zavier has 24 more pencils than Xiumin at first. How many pencils do the 3 children have altogether?

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.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

- (2, -7)

- lines r and s and lines t and u must be parallel
