Answer: x = -3
Step-by-step explanation:
12x - 9 = 10x - 15
Add 9 to each side
12x = 10x - 6
Subtract 10x from each side
2x = -6
Divide by 2
x = -3

Step-by-step explanation:
4.20 ÷ 60 = 0.07
sales tax is 7% and this is your constant of variation
On week 1, we started with a deposit of $200. Every week from that point on, we place a deposit of $55.
We know y is total amount of money (deposits) in the bank account.
We also know x represents the number of weeks.
On week 1, we would have $200 in the back account.
On week 2, we would have $200 + $55 or $255 in the bank account.
So, we could build an expression of 55(x - 1) + 200 which is equal to y.
So, y = 55(x - 1) + 200 is the answer.
The first step to simplify this equation is to multiply the numbers

×

next,, youll multiply the terms with the same base by adding their exponents
1512

finally,, youll add the numbers together
1512

since you cant simplify any further,, the correct answer to your question is 1512

let me know if you have any further questions
