A prime number is a number that can only be divided for 1 and itself.
The right answer is B, 1053 is NOT prime. It can be divided for 1, 3, 9, 13, 27, 39, 81, 117, 351, 1053.
Answer: 12 months (1 year)
We know that Alision gains $29.26 each month. She wants to buy a stereo for $339.12
You want to divide $339.12 with $29.26 to find the total months.
339.12 / 29.26 = 11.6
CHECK:
You want to round up, since she needs the money to buy a stereo. She's allowed to have more money.
29.26 * 12 = 351.12
It will take Alision 12 months (1 year) to buy her stereo.
8x - 6 - 12x^2 + 9x
2(4x-3)-3x(3x-3)
=> (2-3x)(3x-3)
=> 3(x-1)(2-3x)
Answer: x = -6
Step-by-step explanation: The problem gave us the y value, so we can just substitute it into the equation and solve it.
y = x - 6
y = 2x
2x = x - 6 (substitute the y value into the equation)
1x = -6 (subtract x on each side)
x = -6 (1x is basically saying x so you do not need to divide)
Answer:
Step-by-step explanation:
WITHOUT replacement of first card drawn:
P(a 10 is drawn) = 13/52 = 1/4
P(the next draw is a 10) = 12/52 = 3/13
P(drawing two 10s without replacement of the first draw) = (1/4)(3/13) = 3/52
WITH replacement of first card:
P(two 10s are drawn) = P(first card is a 10)*P(first card is a 10) = (4/13)(4/13) =
16/169
