The answer depends on what the percentage problem is. The equations will be different depending on whether you want to find:one number as a percentage of another,a given percentage of a number,the percentage change applied to a given number,find the original number if given the number after the percentage change.
you have to write down the equation first so people can answer it
i dont know hahaha
55x/100 = 29.7 so 55x = 2970 so x = 2970/55
You write a number, not wright! It would be written as 75% of [the number].
A linear equation in two variables will give an infinite number of solutions. These will comprise the coordinates of points along a straight line in 2-dimensional space.
You do not need to write anything to calculate things mentally.
This problem means to write this equation: 14 = 75/100 * n And we can get n by itself to solve the problem: 14 * 100 /75 = n 1400 / 75 = n 18 2/3 = n
You have to write an equation for this. When you do percents, you always have to convert them to decimals. (Therefore, 80% is .80 as a decimal) .80x = 8 Divide both sides of the equation by .8 and you'll get x = 10
Answer is 5.4 percent because you want equvailent fractions in the equation so thefore you times the decimal value by 100 so equation is 100 times 00.54 equals 5.4 percent. THIS IS THE ANSWER
It's not an equation - there's no "is" or "equals." You can write it as a mathematical *expression*, however:140 "decreased by 20%"140 - (20/100)*140
if n is your number, then 3n - 5 = 16, ie 3n = 21 ie n = 7.
A vertical line has the equation [ x = a number ]. A horizontal line has the equation [ y = a number ].
x2 -y2 =16 This is an equation that describes your problem. We can write this equation as (1/16)x2 -(1/16)y2 =1 You may recognize this as the equation whose graph is a hyperbola. So there are an infinite number of solutions.
X + X/2 = 45 so 3X/2 =45 3X=90 X=30
125 percent (1.25) as a mixed number is: 11/4
There is no equation in the question, only an expression.
you shall add
Read the problem. Write each fact as a variable expression. Write each fact as a sentence.
'51.93' is not an equation. It's a number. When you write or speak it, it comes out "fifty-one and ninety-three hundredths".
You write it as an equation, and then solve the equation.
Remember that "7 percent" means 0.07, and "of" in math usually means "times".Then it's easy to writex = 0.07 times 480
