6-z
Z-6 would be wrong because the question said start with 6
Let S be the amount in a savings account.
Let m be the number of months.
General equation
S = 132 + 27m
Specific question
July is the 7th month of the year including both January and July.
S = 132 + 7*27
S = 132 + 189
S = 321
Reasonableness?
Good question. You could estimate an answer.
Start with 150 dollars and say that you add 25 a month.
7 * 25 = 175
S = 150 + 175 = 325 All of this was done in my head. Since the exact answer obtained using the formula is 321, I think that's pretty reasonable using my estimate is a guide.
Answer:
425+250 times 8.3%
Step-by-step explanation:
Answer: 13°C
Step-by-step explanation:
Subtract 2 from 15.
Answer:
x = 1/2
y = 24
Step-by-step explanation:
y = 12 / x
y = 6 / x²
12 / x = 6 / x²
x² / x = 6 / 12
x = 1 / 2
y = 12 / x
y = 12 / (1/2)
y = 24
