Answer:
Step-by-step explanation:
Given : A man earned x pesos in 10 days and spent y pesos during each of those days.
i.e. Total earning in 10 days = x
Earning per day = [By unitary method] (1)
Money spent per day =y (2)
We know that
i.e. Subtract (2) from (1), we get
Hence, the expression to determine how many pesos he saved per day will be:-
Step-by-step explanation:
Answer:
Exponents
Step-by-step explanation:
exponents are basic short cut to write numbers like 100, 1000, 10000, 1000000 and so on.
Exponents can also be defined as 10 raised to a power x whether positive or negative
They are mostly used in expressing units in standard form.
<h3>examples of basic positive exponents</h3>
basically the power represent the the number of zeroes after the 1.
<h3>examples of basic negative exponents</h3>
in negative exponents the power represents the number of zeroes before the 1. including the 0 behind the decimal point.
this is the basic lay down of how exponent work but one more quick example for maximum understanding
<h3>quick example</h3>
hope you grasp the concept involved in multiplication with other terms.
cheers
y = - 3
Since y varies directly as x then
y = kx ← ( k is the constant of variation )
to find k use y = - 1 when x = 3
k = = = -
hence y = - x
when x = 9, then
y = - × 9 = - 3
The answer is
19 - 12 is 7
19 - 7 is 12
And he stopped 19 today
He stopped 38 people’s in a 3 days periods
