Step-by-step explanation:
Jocab will take 4 more weeks to buy that MP3 player.
<u>Step-by-step explanation:</u>
Given:
Cost of MP3 player = $ 195
Earning per week = $ 225
Expenses per week = $ 180
To Find:
Weeks still required to save money for buying MP3 player.
Formula to be used:
Savings per week = Earning - Expenses
Solution:
Savings per week = Earning - Expenses
= $ 225 - $ 180 = $ 45
Already saved = $ 55
Need to save = $ 195 - $ 55 = $ 140
So for 4 weeks savings = $ 45 × 4 = $ 180
Thus Jocab will take 4 more weeks to buy that MP3 player.
Answer:
4x - 16
Step-by-step explanation:
A triangle is a three sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
the perimeter of a triangle = sum of the side lengths
let the unknown length be represented with y
13x - 21 = 4x + 3 + 5x - 8 + y
13x- 21 = 9x - 5 + y
Make y the subject of the formula
13x - 21 - 9x + 5 = y
4x - 16 = y
the side length = 4x - 16
