Exponent is the expression in where you convert product factor expression into a shorter expression. So really you use it to make the question simpler and shorter(easier to understand).
The height of the candles when they first burn down to the same height is 10 cm
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let y represent the height of the candle after x hours.
For the first candle:
y = -(5/6)x + 15
For the second candle:
y = -(5/2)x + 25
To have the same height:
-(5/6)x + 15 = -(5/2)x + 25
x = 6 hours
y = -(5/2)(6) + 25 = 10 cm
The height of the candles when they first burn down to the same height is 10 cm

Answer:
c = 2.9 yards
Step-by-step explanation:
2c = 42.4 - (18.3 x 2)
2c = 42.4 - 36.6
2c = 5.8
c = 5.8 / 2
c = 2.9 yards

If you're confused whether to do multiplication or division first.
<span>Remember PEMDAS. It's the Order of Operation. Basically, it's the order of which operators are prioritized in an equation.
From Highest to Lowest Priority.
Parentheses, Exponents, (Multiplication and Division), and (Addition and Subtraction)
Multiplication and Division have the same priority, as well as Addition and Subtraction.
So for this it is which ever comes first, from left to right of the equation is prioritized.
WORKING:
3x2/3
The multiplication operator comes first, so we do:
3 x 2=6
Finally, we take "6" and divide it by 3
6 / 3 = 2
Answer is: 2</span>
Answer:
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).
Step-by-step explanation:
