AnswEr:
Add the two, to both sides. -2+2=0
So, the equation would like like this
x -2= 9
+2 +2
Then solve, the 2’s cancel out leaving you with x by itself. Finishing the equation to look like this-> x=11
There is no common factor between 15, 17 and 18 because 17 is prime.
15z² +17z - 18 =
d = 17² - 4.15.-18
d = 289 + 1080
d = 1369
z = (-17 +/- \/1369) : 2 * 15
z = (-17 + 37) : 30
z' = 20 : 30 = 2/3
z" = (-17 - 37) : 30
z" = -54 : 30 = -1.8

Answer: I want to help ya, but can you write the problem as an expression?
Answer:
- To make half the recipe, we will need 3/8 Parmesan cheese.
Step-by-step explanation:
<u>We know that:</u>
- Cesar Salad = 3/4 Parmesan cheese
To make 1/2 the recipe, we need to change everything in halves.
<u>Work:</u>
- Cesar Salad = 3/4 Parmesan cheese
- => Cesar Salad/2 = 3/4 ÷ 2 Parmesan cheese
- => Cesar Salad/2 = 3/4 x 1/2 Parmesan cheese
- => <u>Cesar Salad/2 = 3/8 Parmesan cheese</u>
Hence, to make half the recipe, we will need 3/8 Parmesan cheese.
