Total of 7 packs. 12 pencils in a pack. 7x12 = 84
Answer:
P=500
Step-by-step explanation:
My reasoning is multiply 0.05 and 2 and you get 0.1. Then you divide 0.1 out of 50 and get 500. Too check the answer you take 500 and multiply it by 0.05 and then multiply it by 2 and you should get an answer of 50 like it says in the equation.
Answer: 54 students in each bus
Step-by-step explanation:
331 - 7 = 324
324 ÷ 6 = 54.
There were 54 students in each bus.
There are a lot of ways but here are a couple of examples.
1. 1,2,3,4,5 - 1,2,4,5,3 - 1,4,5,3,2...... So on Hope this helps:)
ANSWER
The general solution is
, where
is an integer
<u>EXPLANATION</u>
In order to solve the linear congruence;

We need to determine the inverse of
(which is a Bézout coefficient for 33).
To do that we must first use the Euclidean Algorithm to verify the existence of the inverse by showing that;

Now, here we go;



The greatest common divisor is the last remainder before the remainder of zero.
Hence, the
.
We now express this gcd of 1 as a linear combination of 33 and 280.
We can achieve this by making all the non zero remainders the subject and making a backward substitution.


Equation (2) in equation (1) gives,



The above linear combination tells us that
is the inverse of
.
Now we multiply both sides of our congruence relation by
.

This implies that;

.
Since this is modulo, the solution is not unique because any integral addition or subtraction of the modulo (280 in this case) produces an equivalent solution.
Therefore the general solution is,
, where
is an integer
