the answer is 2 because you can't divided 2 by anything else other then itself
Answer:
x=-1 and y=4
Step-by-step explanation:
y=-3x+1
2x+5y=18
Put x and y on the same side for 1st equation
3x+y=1
2x+5y=18
Multiply top by -5
-15x-5y=-5
2x+5y=18
Add both equations onto each other
-13x=13
x=-1
Plug x=1 into any equation used
2(-1)+5y=18
-2+5y=18
5y=20
y=4
Answer:

Step-by-step explanation: We know that:
and we want:
.
We can form the numerator using just the first fact (since 5^2 is 25) and the denominator using the latter two (since 3*7 = 21).

The logarithm of a division can be expanded by subtracting the numerator and denominator (while still keeping the log). The logarithm of a product can be expanded by adding the terms while keeping the log. If the logarithm is raised to a power, we can bring it down as a factor:

.
Substituting the variables:

30%. All you have to do to convert decimal to percent is move the decimal over two to the left.
Answer:
1) 4y + 4y + 8
2) 8y + 8
Step-by-step explanation:
The first equation is just re arranging the equation.
The second equation is combining like terms.
Hope this helps :)
