What about it? 7x+5 equals what
Answer:
The answer is
Step-by-step explanation:
The following steps will give a solution to the congruence
1. <em>Compute Euler's Phi function .</em>
We have by prime factorization, so that
because where p is a prime number.
2. <em>Find positive integers u and v that satisfy .</em>
We know a solution exists, since , using the Euclidean algorithm allows us to find the solution
In order to get positive values for <em>u</em> and <em>v</em>, we modify this solution:
and
The equation
provides the key to solving the original problem.
3. <em>Compute by successive squaring. The value obtained gives the solution x.</em>
We have , so
To use this method start by looking at the exponent 929 and represent it as a sum of powers of 2 this is called the binary expansion of 929. To do this, find the largest power of 2 less than your exponent in this case it’s . Subtract 512 from 929 getting 417. And continue in this manner to get:
Now
So all you have to do is to calculate the numbers
and multiply them together, then take the product
They are all true None are false
Answer:
Distance cover by Jodie = 1 kilometer
Step-by-step explanation:
Given;
Speed of Jodie = 6 kilometer/ hour
Total time Jodie ran = 10 minutes
Find:
Distance cover by Jodie
Computation:
Total time Jodie ran = 10 minutes = 10 / 60 = 0.1667 hour
Distance = Speed x time
Distance cover by Jodie = Speed of Jodie x Total time Jodie ran
Distance cover by Jodie = 6 x 0.1667
Distance cover by Jodie = 1.002
Distance cover by Jodie = 1 kilometer
Answer:
Inequalities work exactly like equations with one exception. The process begins just like equations: first, do the opposite of what you see, then do the same thing on the other side of the sign. At the last step of solving an inequality, if you multiply or divide by a negative number, then you reverse the sign
