Need a two step equation for number 3

so the bike costs $129, but she already has $24 saved, then she'll be saving $3 per week so let's take a peek at a table of those savings

week 1..................... total amount......... 24 + 3(1)

week 2..................... total amount......... 24 + 3(2)

week 3..................... total amount......... 24 + 3(3)

week 4..................... total amount......... 24 + 3(4)

week 5..................... total amount......... 24 + 3(5)

week w..................... total amount......... 24 + 3(w)

24 + 3x = 129

35 weeks

Step-by-step explanation:

She already has 24 dollars saved, but will save 3 dollars every week. Use x to represent the number of weeks. In total she will save 129.

Solve for x using the equation:

24-24 + 3x = 129-24

3x = 105

3x/3 = 105/3

x= 35

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 don't see any
