Step-by-step explanation:
Do 4 1/4+ 3 1/3= 7 3/4
11- 7 3/4= 3 1/4
Hope this helped. Thank me later.
Two Geometric figures are similar if you can go from one to another only through rotation (spinning), translation(moving WITHOUT rotating), reflection (making a simetry) or scaling (like zooming)
When scaling, you have to scale both vertical and horizontal axis at the same rate (example, 2x, 7x or 0.3x)
As such, all squares are similar and so are all REGULAR poligons among each other (all equilateral triangles are similar, all regular pentagons, etc)
This gets a bit tricky if the polygons are not regular, but the principle remains the same. For example, if you have a triangle with sides measuring 2,5 and 4, it will be similar to a triangle with sides measuring 8, 20 and 16, because you have scaled it 4x, hence, it's internal angle remained the same.
Answer: i think C
Step-by-step explanation: Well the X Value would have to change because if you graphed it it would be a straight line going up which wouldnt pass a through a vertical line.
Answer:
The donuts cost $0.75 and the cookies cost $0.6
Step-by-step explanation:
You need to create a system of equations:
20d + 30c = 33
5d + 2c = 4.95
Now, let's isolate the cookies on the second equation:
2c = 4.95 - 5d
Multiply it per 15 to get the value of 30 cookies:
30c = 74.25 - 75d
Substitute in the first equation:
20d + 74.25 - 75d = 33
-55d = -41.25
d = -41.25/-55
d = 0.75
Now substitute the value of d in the second equation to find the value of c:
5•0.75 + 2c = 4.95
3.75 + 2c = 4.95
2c = 4.95 - 3.75
2c = 1.2
c = 1.2/2
c = 0.6
