8x7x6 = 336. There are 8 possible options for slot 1, then 7 for 2, and 6 for the last slot.
Hello,
First we work out the equations:
x + y =62 will be the first equation.
2x= y +13 is the second equation.
We can first rewrite the second equation as 2x – y =13.
So we have:
x + y = 62
2x –y =13
KEEP IN MIND: With y being positive in one of the equations and negative in the other, we can combine the equations to quickly eliminate y and solve for x.
x + y = 62
+2x –y =13
3x = 75 divide both sides by 3 to get x.
x = 25
Now that we have x we can substitute the value for x, 25.
25 + y = 62 we can subtract 25 from both sides to get y.
y = 62- 25
y = 37
2(25) = 37 + 13
Therefore,
50 = 50
Have a amazing day.
Step-by-step explanation:
The square root of a fraction is the square root of the numerator over the square root of the denominator. In this case, 1/4. The square root of 1/16 = 1/4 Ans.

Answer:
c=6
Step-by-step explanation:
c-20-4-3c
c-20+20= 4+20-3c
c=24-3c
c+3c=24-3c + 3c
4c = 24
4c 4 24 4 =
c = 6
