First of all why is there 2 similar equation connected to one another?
Second in order to solve this all you need to do is plug in the number and solve for x
For 485
85x+60=485
85x=420
X=5
Do the same thing and you get 3
Answer:
Step-by-step explanation:
The equation which is equivalent to 60% of 25 are x • 1.6 = 25, 0.6 • 25 = x and x/25=60//100
Percentages can be expressed as decimals or fractions.
Given the expression 60% of 25, this can b expressed as:
where x is the result of the expression.
Expressing 60% as a decimal will give;
0.6 of 25 = x
0.6 * 25 = x
From the expression 60/100 * 25 = x, this can also be written as:
25 = 100/60 x
25 = 10/6 x
25 = 1.6x
Hence the equation which is equivalent to 60% of 25 are x • 1.6 = 25, 0.6 • 25 = x and x/25=60//100
