Answer:
x=10/14 or 0.714
Step-by-step explanation:
1. (4/5)*(5/7) = (4/5)x
2. 20/35 = 4x/5

An equilateral triangle have 3 congruent sides.
Divide the total (15x +3) by 3
(15x + 3)/3 = 5x + 1
Each side's length is 5x + 1

A percentage is a way to describe a part of a whole. The money that is raised by Nina in the second month is $960.
<h3>What are Percentages?</h3>
A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the money raised by Nina in the first month is $800, while the money raised by Nina in the second month is 20% more.
Therefore, the money raised by Nina in the second month is,
Money raised = $800 + 20% of $800
= $800 + 0.20($800)
= $800 + $160
= $960
Hence, the money that is raised by Nina in the second month is $960.
