Answer:

1.42%

Step-by-step explanation:

let y be the unknown number

49% × y = 49y%

49y% = 56

then the co-efficient of 'y' that is 49% will cancel out leaving 'y' and resulting in 56÷49 resulting in 1.42

therefore the original number is 1.42

Sydney is playing a game on a map with a marked grid. To start, she places a game piece at (1, 4). She moves 3 units east and 2
Anastasy [175]

Answer:

(7, 8)

Step-by-step explanation:

If Sidney places each piece 3 units east and 2 units north of the last one, we can figure out which coordinate comes first by subtracting the position of the second piece (S) by the position of the first piece (F):

S - F = (4,6) - (1,4) = (3,2)

We can conclude that coordinates are in the (East, North) format.

Therefore, the location of the third piece (T) is:

T = S(E,N) +(3,2)= (4,6)+(3,2)\\T = (7,8)

Slope (12,-18),(11,12)
olga nikolaevna [1]
If you are trying to find the slope using only these two points then you should first take note of what your X and Y values are. For instance, 12 & 11 are your X values and -18 & 12 are your Y values. Knowing this you can now find your slope by doing y2-y1/
x2-x1. You will get the fraction -30/1 or -30 which is your slope. Hope that made sense!
