Answer:
y = -5
Step-by-step explanation:
Isolate y:
-3x + 9y = -57
9y = -57 + 3x
y = (-57/9) + (3/9)x
Substitute for x:
y = (-57/9) + (3/9)(4)
y = (-57/9) + (12/9)
y = (-45/9)
y = -5
It is C. Because it says that 8+ the product of 2 and a number to the third power, what it means 2×m cubed. So it is 8+2m (cubed)
Answer:
T
Step-by-step explanation:
Answer:
Option B
Step-by-step explanation:
to find the answer, you're going to break the phrase into different parts
these parts would be "13 more than", and "the product of 4 and a number, n"
"13 more than" means that you are adding 13 to the pile, so algebraically, this would be written as "+13" or "13+"
"the product of 4 and a number, n" is one thing, but it can be broken down even further to "the product of" and "4 and a number, n"
"the product of" means a multiplication sign, I know this because the term for the answer of multiplying numbers is "product"
"4 and a number, n" means that it is one thing that includes 4 and <em>n </em>together, so this would create 4n
if you put this all together, you would get "4n + 13" or "13 + 4n", these are the same thing, just written in different orders
If the number following the decimal point is 5 or more the number is rounded up
if the number following the decimal point is 4 or less the number stays the same or is rounded down depending on what the question is asking.
In this case the 6 rounds your answer up to 759
hope this helps :)
