Start by simply rewriting the equation
x-6y=48
Then transfer any other variables or numbers through addition or subtraction so that the y is isolated on one side of the equals sign
(in this case, subtract the x so that it moves to the other side of the equal sign)
-6y =48 -x
Finally, do any multiplication or division to cancel out anything still attached to the y.
y = -8 +

(in this case, divide by -6)
Now the y has been fully isolated on one side of the equal sign and you can see that x - 6y = 48, solved for y, is <span>y = -8 +

.
I do not see any way to simplify this further, though it is possible I am missing something.</span>
Answer:
4095
Step-by-step explanation:
This can be evaluated by substituting n = 1 to n = 6 into the expression and summing the terms, that is
3(
)
= 3(
+
+ 4² + 4³ +
+
)
= 3(1 + 4 + 16 + 64 + 256 + 1024)
= 3(1365)
= 3 × 1365
= 4095
Answer:
36
Step-by-step explanation:
There are 30 red marbles and the ratio of black to yellow is 4/5, so 4/5=orange/green=orange/30.
30 is 6 times 5, so black=6 times 4=24. There are 24 black marbles.
Total of black and yellow=24+30=54.
40% of the marbles are green so 60% are black/yellow. Also 60% is 54 marbles.
60% is 60/100=3/5 so 3/5 of the total is 54 marbles, therefore 1/5 is 54/3=18 and 2/5 is the number of red marbles=2 times 18=36 red marbles.
to be honest i can't think of anything original for the visual thing, but i think the pi chart from the person above me would work well
The answer is square root of 175. To get the answer first you have to first have the equation a^2+b^2=c^2. So your new equation would be a^2+15^2=20^2. Since 20^2 equals to 400 and 15^2 equals to 225. All you have to do is 400-225 which is 175. Since there is no two same numbers that can multiply to get 175 you leave it as square root of 175.
Answer:
2/3
Step-by-step explanation:
= 3/4 * 8/9
= 24/36
simplify by 4
= 6/9
simplify by 3
= 2/3
