Rewriting the question, the given lengths that were cut from the board were 30 3/4 inches, 12 1/4 inches, and 16 1/4 inches. To obtain the remaining length of the board, all of the measurements cut are to be added and subtracted from 72 inches. This is shown below:
30 3/4 + 12 1/4 + 16 1/4 = 237/4 = 59.25 inches.
Remaining length of board = 72 - 59.25 = 12.75 inches.
Therefore, there will be 12.75 inches remaining of the board.
Answer:
The solutions are 1 , -6
Step-by-step explanation:
∵ (x + 2)(x + 3) = 12
∴ x² + 3x + 2x + 6 - 12 = 0
∴ x² + 5x - 6 = 0
∴ (x - 1)(x + 6) = 0
∴ x - 1 = 0 ⇒ ∴ x = 1
∴ x + 6 = 0 ⇒ x = -6
Well there can be two different solutions for this but i will choose the easier one. Obviously one requires a system of equations which obviously will involve a lot of thinking and some good algebra solving in order for them to solve.
As for hit and trial it is very easy, we can just keep adding the distance as we know they are in different directions. 60 + 61= 121. So 121 x 4.5 = 544.5 miles. So after around 4.5 hours they will be 544.5 miles apart if they continue at the same pace.
Answer:
An integer is a whole number, positive or negative. A rational number is a number which can be expressed as a fraction between 2 whole numbers. An integer is a rational number, because every integer can be expressed as a fraction between itself and 1, both whole numbers.
