Answer:
Multiply the second equation by −2 to get −8x − 6y = −30.
Step-by-step explanation:
we have
----> first equation
----> second equation
Solve by elimination
Multiply the second equation by -2 both sides
---> equivalent second equation
Adds first equation and the equivalent second equation
Find the value of y
substitute the value of x in any of the equation
the solution of the system is the point (3,1)
To find 9 copies of 3.65, we multiply 3.65 by 9. The result of this multiplication is 32.85.
The question is asking for 9 copies of 3.65, which means you are to take the number 3.65 and multiply it by 9. Multiplication is the operation you would perform when a question asks how much is 'x copies' of a number. In mathematics, this is equal to repeated addition of the number. Therefore, 9 copies of 3.65, or 3.65 multiplied by 9, is equal to 32.85.
