Math Riddle From Kenyan Bank
26 Very Few Can Solve This
Suppose 7 +3 = z.
8+1 = 79
Find a different pair
6+5=111
of numbers x, y where
x + y = z.
4+2=26
8+1=79
6+5=111
7+3=?
please solve the riddle
To solve the riddle, we need to find a pattern in the given equations.
In the first equation, 7 + 3 equals z. We don't know the value of z yet, but we can calculate it by adding 7 and 3, which gives us 10.
Now, looking at the second equation, 8 + 1 equals 79. This does not follow the usual addition rules, but if we concatenate the digits, we get the number 79.
Similarly, in the third equation, 6 + 5 equals 111, which is obtained by concatenating the digits 6, 5, and 5.
Based on this pattern, we can solve the riddle by concatenating the digits of the numbers in the equation 7 + 3 = z.
Therefore, 7 + 3 = 73.
The formula M 0.62K can be used to convert distances in kilometres (K) into miles (M). Use the
formula to convert the following distances into miles:
a. 100kilometres
b. 250 kilometres
c. 15 kilometres
To convert distances from kilometers (K) to miles (M) using the formula M = 0.62K, we can substitute the given values into the formula.
a. To convert 100 kilometers:
M = 0.62 * 100 = 62 miles
b. To convert 250 kilometers:
M = 0.62 * 250 = 155 miles
c. To convert 15 kilometers:
M = 0.62 * 15 = 9.3 miles
First simplify the following expressions, then determine the value of the expression by substituting
a. &1+2a
b. 7a-a+5
a. To simplify the expression 1 + 2a:
This expression cannot be simplified further since it is already in its simplest form. We don't have any like terms to combine or any operations to perform.
b. To simplify the expression 7a - a + 5:
We can combine the like terms "7a" and "-a" to simplify the expression:
7a - a + 5 = 6a + 5
Now, the expression is simplified to 6a + 5.
To determine the value of the simplified expression, we need a specific value for "a" to substitute into the expression. Without a value for "a", we cannot determine a numerical value for the expression.
