Write and solve an equation, as follows:
-7y + 5(3+ny) = 3y + 15. We are to find the value of 'n.'
-7y + 15 + 5ny = 3y + 15.
Subtracting 15 from both sides, we get -7y + 5ny = 3y
Grouping like terms, we get 5ny = 3y + 7y = 10y
Dividing both sides by 5y, we get n = 2 (answer)
Answer:
x is less than or equal to 9
which is x ≤ 9
Step-by-step explanation:
Greta starts with $100 in her savings account
She adds $50 each week
Balance after week 1 = 100 + 50 = 150
Part A
Unit rate of change here is = 
⇒ Unit rate of change here is = 
⇒ Unit rate of change here is = 50%
Part B
Equation to calculate the amount of money Greta will have after any number of weeks = ?
Money after 'x' number of weeks = 
⇒ Money after 'x' number of weeks = 
Part C
Money Greta will have after 1 year= ?
In a year there are 52 weeks
So, putting x = 52 in the solution of Part B
⇒ Money after 52 weeks = 
⇒ Money after 52 weeks = 
⇒ Money after 52 weeks = 2,700
3(y-9)-y=7
3y - 27 -y = 7
2y = 34
Y = 17
3(x) -17 = 7
3x = 24
X = 8
