Answer: (x-9)/2 = y
Basically, we ned to get y by itself. I started by multiplying both sides of the equation by y, which will cancel it out from the left side. That gives me x-9 = 2y.
Now, we're going to divide both sides by 2.
That gives me (x-9)/2 = y, which is your answer! I'll attach a photo of the work I did, I hope it makes sense! :)
Answer:
x is y less than z
Step-by-step explanation:
The given equation is x + y = z
This equation relates the whole numbers x, y, and z.
This equation can be rearranged to make x the subject of the formula or to make y the subject of the formula. When this is done, the relationship between the terms or numbers would be clearly expressed.
Making y the subject of the formula, it becomes
y = z-x (this shows that z is greater than y by x)
Making x the subject of the formula, it becomes
x = z-y (this shows that z is greater than x by y)
Looking at the options given, the correct comparisons between z and x is
x is y less than z
Where are the measurements
Answer:
The equation that models the cost of each bracelet is . Cost of each bracelet is $7.
Step-by-step explanation:
Let the cost of each bracelet is defined by the variable x.
Cost of 9 bracelet is 9x. The shipping cost is $9. Therefore the total cost of 9 bracelets, including shipping is
The total cost for 9 bracelets, including shipping is $72.
Subtract 9 from both sides
Divide both sides by 9.
Therefore the cost of each bracelet without shipping changes is $7.
Answer:
yes
Step-by-step explanation:
A difference of squares has the form a² - b² = (a - b)(a + b)
note that 36z² = (6z)² ⇒ a = 6z and 9 = 3² ⇒ b = 3
36z² - 9 is a difference of squares and factors as (6z - 3)(6z + 3)
