The probability that Lou's guess is correct would be 0 % of expressed as a percentage. This is because this is not one of the descriptions that Layla is thinking of, when she is thinking of a single digit number. 7 is not an even number, but an odd one.
Answer:
mathematics is inclusive, so A or B is a set of things where each of them must be ... Kevin Houston in his book[2] gives an idea to think of a proof
Step-by-step explanation:
Answer:
The mistake was made in the second step when going from 3x - 2(3x-4) = 13 to 3x - 6x - 8 = 13.
The mistake was in the multiplication of -2(3x-4). The error is that the negative sign was not distributed to both the 3x and the -4.
-2 times 3x is -6x and -2 times -4 is positive 8
Step-by-step explanation:
y = 3x - 4
3x - 2y = 13
------------------------
3x - 2(3x - 4) = 13
3x - 6x + 8 = 13
-3x + 8 = 13
-3x = 5
x = -5/3
y = 3(-5/3) - 4
y = -5 - 4
y = -9
Solution: x = -5/3 and y = -9
Answer:
She colored 30 yellow place value disks and 50 disks are left to color.
Step-by-step explanation:
Let total number of disks be x.
It is given that, she colored 2/6 of the disks red. She colored 1/4 of the disks yellow.
She colored 40 red place value disks.
It means total number of disks is 120.
So, she colored 30 yellow place value disks.
Remaining disks = Total disks - Red disks - Yellow disks
Therefore, 50 disks are left to color.
