Answer:
The answer is QR and TS are parallel. QT and RS are parallel
Step-by-step explanation:
You can find the slope of each line using the formula y2-y1/x2-x1 and to help organize your ideas or understand better, you can graph the points in a cardinal plane.
16/14 = 8/7
-------------------------
64/60 = 32/30 = 16/15
-----------------------------
The answer is no.
8/7≈1.14
16/15≈1.07
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
The other factor is 6 cause 4x6=24 and 4 is one factor but also 6
