Odd numbers end in a 1,3,5,7,9 and the hundreds place is like this blank. _45. It is a multiple of 10 if it ends in a 0.
We are told that 21% of the total cans is 63 cans, therefore
100% of all the cans collected would be.
(63*100)/21=300 cans were collected in all
<span>An algebraic expression is an expression constructed from a number of constants and variables utilizing algebraic operations. These algebraic operations are addition, subtraction, multiplication, division, and exponentiation. A constant is constant, so its value is unchanged. A variable changes based on the value provided. In the provided example, 2x-1, there are two constants, "2" and "1", and one variable "x." The algebraic operations utilized are multiplication and subtraction. In order to evaluate the value of the algebraic expression, the given value for the variable must be substituted for the variable x, and then the algebraic operations executed to obtain the answer.
For instance, if you were told that the value of x in this case was 2, then you would substitute the value 2 for x and perform the described operations. Remember to follow the order of operations when evaluating an algebraic expression!
2x-1 for x=2
2(2) - 1
4 - 1
3 is the answer.
Remember, even though the multiplication operation is not explicitly stated, it is implied that a constant attached to a variable (termed a coefficient) is multiplied with the value of the variable.</span>
Answer:
Step-by-step explanation:
There is 2n+150 litres of oil in total. We have to divide this oil into 3 equal parts which will be named Tank A, Tank B, Tank C.
C was empty at first, then it was delivered 500 litres in total. So if every tank was supposed to have one thirds of it, that means one thirds of the oil equals to 500 litres.
All of the oil would be 500x3=1500 litres
2n+150 was the formula to our total litre count, so if we make a connection between them, we can solve this question for the value of n.
2n+150=1500
2n=1350
n=675
