Answer:
K=10
Step-by-step explanation:
So first distribute
3x-12=18
add 12 on both sides
3x=30
Divide 3 on each side
x=10
When you multiply the equation 1 by 1, then it won't change and will be:
<span>6x − 2y = 3
Now, when you'll add 2nd equation to it, then, it is:
= 11x + y = 7
In short, Your Answer would be Option D) </span><span>Show that the solution to the system of equations 11x + y = 7 and 5x + 3y = 4 is the same as the solution to the given system of equations
Hope this helps!</span>
She has 90 markers because 18 times 5 is 90
8724/25 = 348.96
When you say "over" that means that it has to be divided that short subtraction sign that separates the numerator and the denominator and also means divide so I believe that if you divide you can find the decimal.
