Question:
Find the value of the letter in each of the following and give reasons for the steps involved:
1 2 A
+ 6 A B =
A 0 9
Answer:
128 + 681 = 809
Step-by-step explanation:
Here, let's use the general form of numbers where any letter must represent one value and each digit must be represented by just one letter.
Take the following:
A = 8
B = 1
Thus, A +B = 8 + 1 = 9
Also add:
8 + 2 = 10
In general form, tens digit is zero and the 1 is carried over.
I.e, A = 1 + 6 + 1 = 8
We can now see that,
A = 8
B = 1
Therefore,
1 2 A
+ 6 A B =
A 0 9
Will be written as:
128 + 681 = 809
Answer:
<h2><u><em>
A 4 + 12+2 = 18</em></u></h2>
Step-by-step explanation:
which expression is equivalent to 4+ [4 x (5-2)] + 2?
A 4 + 12+2
B 4 + 18 + 2
C 8x3 + 2
D 8 x 5 - 1
4+ [4 x (5-2)] + 2 = 18
A 4 + 12+2 = 18
B 4 + 18 + 2 = 24
C 8x3 + 2 = 26
D 8 x 5 - 1 = 39
check
4 + [4 x (5-2)]+ 2 = 4 + 12 + 2
18 = 18
the answer is good
0 5
4 2
= (0 x 2) - (5 x 4) = -20
