Answer:
42
Step-by-step explanation:
there are a possible 6 combinations for a sum of 7:
1,6
6,1
2,5
5,2
3,4
4,3
so we can create this proportion:
7/36 = n/216
n = # times to roll a sum of 7 out of 216
now cross-multiply:
36n = 1512
n = 1512/36
n = 42
Answer:
The sum of 3 and the quotient of y and 2.
Step-by-step explanation:
Lets say the race is x km long.
That means she ran 65% of x.
And that also means that 65% of x = 3
So 65%*x=3
65/100x=3
x=3*100/65
x=300/65
x=4.62
Answer:
D) 8x²-172x+120
Step-by-step explanation:
Length=2(-2x+20)+6
Width=-2x+20
(-4x+40+6)(-2x+20)
(-4x+46)(-2x+20)
8x²-80x-92x+920
8x²-172x+920
Start with 1.
1st number = 1
2nd number = 1 * 4 + 3 = 7
3rd number = 7 * 4 + 3 = 31
4th = 31 * 4 + 3 = 127
5th = 127 * 4 + 3 = 511
Which means the 6th = 511 * 4 + 3, which is 2047.
