Solve the literal equation for y, 2x-2y=5
Answers
We can see here that the equation solved for y is: y = (2x - 5) / 2.
How we arrived at the solution?
To solve the given literal equation for y, follow these steps:
Given equation: 2x - 2y = 5
Step 1: Subtract 2x from both sides of the equation to isolate the term with y on the left side.
2x - 2y - 2x = 5 - 2x
-2y = -2x + 5
Step 2: Divide both sides by -2 to solve for y.
(-2y) / -2 = (-2x + 5) / -2
y = (2x - 5) / 2
So, the equation solved for y is: y = (2x - 5) / 2.

Answer:
(a) 1 - (15 C 6) / (30 C 6)
(b) (5 C 2) x (10 C 2) x (15 C 2) / (30 C 2)
Step-by-step explanation:
Number of nickels = 5
Number of dimes = 10
Number of quarters = 15
(a) The probability of getting 6 quarters
= (15 C 6) / (30 C 6)
So, the probability of not getting 6 quarters = 1 - (15 C 6) / (30 C 6)
(b) Probability of getting 2 nickels , 2 dimes and 2 quarters
= (5 C 2) x (10 C 2) x (15 C 2) / (30 C 2)

Always Remeber Dependant Variable Is What Were Observing, And Independant Variable Is What Were Changing.
So, In This Case C Is The Dependant Variable, And B Is The Independant Variable.
I Hoped This Helped!
Answer:
C is dependent, B is independent
Step-by-step explanation:
The dependent variable is the number that is affected when you change the independent variable—it depends on the independent variable.
Does the number of cookies remaining in the jar depend on the number of cookies in the jar before your visit, or does the number of cookies in the jar before your visit depend on the number of cookies remaining in the jar.
The number of cookies remaining in the jar depends on the number of cookies in the jar before your visit. Therefore, the number of cookies remaining in the jar is the dependent variable, and the number of cookies in the jar before your visit is the independent variable.
Therefore, C is the dependant variable, and B is the independant variable.

Answer:
I will need to buy 22.5 pounds of turkey and pay $23.63
Step-by-step explanation:
Proportions
Each person is planned to eat 2 x 3/8 pound servings of turkey for thanksgiving dinner. This means each person will eat
pounds of turkey.
There are going to be 15 people at the dinner, thus the total turkey needed is:
The turkey costs $1.05 per pound, thus the total cost is
22.5*$1.05 = $23.63
I will need to buy 22.5 pounds of turkey and pay $23.63
