Let the number be x.
7x-x=42
6x=42
x=7
the number is 7
Answer:
420 points
Step-by-step explanation:
multiply 7 by 60
Let us assume that the number of pieces that can be cut = x
Length of each shelf board = 1 1/3 feet
= 4/3 feet
Total length of board available for making shelf = 18 foot
Then
4x/3 = 18
4x = 18 * 3
4x = 54
x = 54/4
= 13 2/4
As we can see from the above deduction, 13 shelf's can be made from the 18 foot board. There will be about 2/4th of the board remaining, but that 2/4th part will be wasted as it cannot create a complete board.I hope the answer is to your satisfaction and the explanation is clear to you.
F(x) = 2(x + 3), now if we distribute the 2, we get 2x + 6.
we know the lbs of apple is "x", and therefore, the lbs of orange will be the constant 3.
2x will then stand for the price for "x" lbs of apples.
and 2*3 will stand for the price of "3" lbs of oranges, which is 6 bucks.
since the 2 is multiplying the lbs quantity, it must then be the price, so both cost 2 bucks each per pound.
