In math, the word unknown is also called to the missing term of a number sentence. This missing term is a missing piece that has to be solved.
Let us have A x 60 = 120, since A has no numerical value, it is considered as the missing term. How can we get the value of the missing term? first, study the number sentence. Find out the rule, then apply it.
The value of A on the equation above is 2. Here's how:
A x 60 = 120
A=120÷60
A=2
The value A is 2, therefore the missing term is 2.
The first five terms are: 35, 39, 43, 47, 51
We start with 35 and add on 4 each time to get the next term
35 = first term
35+4 = 39 = second term
39+4 = 43 = third term
43+4 = 47 = fourth term
47+4 = 51 = fifth term
and so on...
Answer:
0.9
Step-by-step explanation:
X=9
Explanation:
A^2 + B^2 = C^2
C^2 - B^2 = A^2
15^2 - 12^2 = A^2
225 - 144 = A^2
81 = A^2
Square root 81 = 9
9 =A
X=9
