Answer:
24 of those times would be tails.
Step-by-step explanation:
Because if you flip it 20 times and it lands on tails 6 times, you just have to add 20+20 6+6 so then it's 40 flips and 12 tails. 60 times and 18 tails 8p times and 24 tails.
<span>B. (1, –3)
</span><span>x – y = 4
8x + 2y = 2
1 - (-3) = 4
8(1) + 2(-3) =
8 - 6 = 2
True

It would be 4r + 3b because If one red marble worth four points and blue marble worth 3 points each then we need to multiply the total number of marbles and calculate the sum. It would give the total number of points.
Answer:
Try 64. I think its right. I could be wrong though
Step-by-step explanation:
The number is x
it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero
x-7=0
x=7
this is not the answer because we were told the number was negative
x+4=0
x=-4
correct
the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check
the number is -4
