Answer: OPTION B.

Step-by-step explanation:

Given the following System of equations:

$\left \{ {{3x-5y=19} \atop {x+y=1}} \right.$

You can use the Elimination Method to solve it. The steps are:

1. You can mutliply the second equation by -3.

2. Then you must add the equations.

3. Solve for the variable "y".

Then:

$\left \{ {{3x-5y=19} \atop {-3x-3y=-3}} \right.\\.....................\\-8y=16\\\\y=\frac{16}{-8}\\\\y=-2$

4. Now that you know the value of the variable "y", you must substitute it into any original equation.

5. The final step is to solve for "x" in order to find its value.

Then:

$x+(-2)=1\\\\x=1+2\\\\x=3$

Therefore, the solution is:

$(3,-2)$

Seven cakes cost £2.10 how much do 10 cakes cost

Len [333]

Ten cakes costs $2.19 (pounds, but I don't have a pounds symbol on my computer) because if you divide $2.10 by seven you get $0.3, and if you add 3×0.3 (because we have seven, and we need to add three more to get ten) we get $0.9.

0.9+2.10=2.19

For all positive integers n, let *n* equal the greatest prime number that is a divisor of n. What does *10*/*12* equal?

artcher [175]

9514 1404 393

Answer:

5/3

Step-by-step explanation:

The prime factorizations are ...

10 = 2·5

12 = 2·2·3

Then *10* = 5 and *12* = 3, so *10*/*12* = 5/3.
