The linear equation that represent the situation is 3b - 6 = 45.
The value of b is 17.
<h3>How to represent a linear equation?</h3>
The situation forms a linear equation. Therefore,
y = mx + b
where
Therefore, let's model the equation linearly,
where
- b = number of books bought
She bought the book for $3 each and receive a discount of $6. The total money spent after the discount is $45.
Therefore, the equation is as follows
3b - 6 = 45
The value of b is as follows;
3b - 6 = 45
3b = 45 + 6
3b = 51
b = 51 / 3
b = 17

Answer:
1. 6, 4. 27s, 6. 11mn/ 7. 12(3x+2), 8. 3(2+x), 11. 2(x-2)
Step-by-step explanation:
the GCF is the highest factor that can go into each monomial, 27s factors are 27 and 1 as well as s, 57st factors are 26 and 2 as well as 57 and 1, with s and t. the highest factor is 27 with s, or 27s. the same thing applies with factoring monomias just take out the GCF and multiply it by what's left. 6 has factors of 6 and 1 as well as 2 and 3, 3x has factors of 3 and 1 with x take the common 3 out and your left with 3(2+1x) or 3(2+x).
Ok....we need lowest common multiple of 0.40, 0.50, 0.80...and that is gonna be : 4.00......so the customer spends $ 4.00
