A student provided the following solution for solving an equation What mistake did the student make? In the third line of the solution 3a should be
subtracted from each side instead of adding a to
each side
Original equation:
3(a - 2)+14 = 8-6
In the second line of the solution like terms were
combined incorrectly.
Solution: 3a - 2 + 14 =8-6a
3a + 12 = 8-60
9a + 128
9a --4
In the last line of the solution, the final answer
should be instead of -
4
9
In the first line of the solution, the distributive
property was applied incorrectly.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

i am pretty sure

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
