Answer:
24
Step-by-step explanation:
Lets start by working out 80% of 30
80% x 30=24
so the student answered 24 questions correctly
The answer to the question
Answer:
Step-by-step explanation:
Our approach here is to isolate X, and simplify this solution. We want to begin by subtracting matrix 2, as shown below, from either side - the first step in isolating X. Afterwards we can multiply either side by the inverse of matrix 1, the co - efficient of X, such that X is now isolated. We can then simplify this value.
Given,
: Matrix 1
: Matrix 2
( Subtract Matrix 2 from either side )
( Simplify )
( Substitute )
( Multiply either side by inverse of Matrix 1 )
- let's say that this is Matrix 3. Our solution would hence be Matrix 3.
Brad sent 11,472 more than leo.
to solve-
5,736 x 3 = 17,208
17,208 - 5,736 = 11,472
