The values of x are x = -0.77 and x = 3.27

<h3>How to determine the value of x?</h3>

To calculate the value of x. we start by using the following equivalent ratio

2x : (3.5 + x + 1.5) = x + 0.5 : x + 1.5

Evaluate the like terms

2x : (5 + x) = x + 0.5 : x + 1.5

Express the ratio as a fraction

2x/5 + x = x + 0.5/x + 1.5

Cross multiply

2x(x + 1.5) = (5 + x)(x + 0.5)

Open the brackets

2x^2 + 3x = 5x + 2.5 + x^2 + 0.5x

Evaluate the like terms

x^2 - 2.5x - 2.5 = 0

Using a graphing calculator, we have

x = -0.77 and x = 3.27

Hence, the values of x are x = -0.77 and x = 3.27

pentagon [3]
He traveled 2080 miles after 4 hours. He covered 3640 miles in 7 hours with a constant speed, so we can calculate the speed: 3640/7=520 miles/hour. After 4 hours, he traveled 520*4=2080 miles.

An item that was selling 72 is reduced to 60. Find the recent decrease in price. Round you answer to the nearest tenth.
Lubov Fominskaja [6]

You need to find what percentage the difference is of 72.  

First, subtract 60 from 72:

72-60=8

Next, divide 8 by 72:

8/72=0.1111

To convert this decimal to a percentage, multiply it by 100:

100*0.1111=11.11

The percent decrease is 11.11%.

Hope this helps!!
