Answer:
Step-by-step explanation:
Given expression:
Convert this into equation and solve for k:
- 33 = k - 15
- k = 33 + 15
- k = 48
So the <u>value of k is 48</u>
f(x) + g(x) = 5x - 3 - 2x + 7
= 3x + 4

Answer:
2:3
Step-by-step explanation:
First, create the ratio by putting the numbers together:
There are 4 red and 6 blue marbles:
4:6
Since both of these are divisible by 2, it can be simplified:
4:6
2:3
So, the ratio of red marbles to blue marbles is 2:3
Step-by-step explanation:
Divide by any number except 0 means the same as multiply by its inverse.
The inverse of 
is 
Therefore
Used the commutative property of multiplication: a × b = b × a
