It is, because Lauren may have gotten a incredibly high score on the first test, and a worse one on the second, while Antoine may have gotten a horrible score for the first test.
Do 2.40 times .3 (you turn the percentage into a decimal and move it forward 2 spaces) and you get .72 so you subtract that from 2.40 and get 1.68
Answer:
it would be d for #1 because it has no solution for the question
Using proportions, it is found that she runs 3.106855 miles in one week.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Researching this problem on the internet, it is found that the measurement is in meters, and we want to find the number of miles. She runs 5,000 meters. Each meter has 0.000621371 miles, hence the number of miles that she runs is given by:
M = 5000 x 0.000621371 = 3.106855 miles .
Maria runs 3.106855 miles in one week.

25y^2+60y+36-24=0
25y^2+60y+8 =0
disctirminant =60^2-4.25.8
disctirminant =3600-800
disctirminant =2800
x1= -60+square root of 2800/2.25
x1= -60+52.91/50= -7.09/50= -0.14
x2= -60- square root of 2800/2.25
x2= -60-52.91/50
x2= -2.25
