Answer:

Step-by-step explanation:

Convert the above mixed numbers to improper fractions through this simple approach: 3 × 10 + 1 /10 = 31/10. Similarly, 2 × 6 + 5 /6 = 17/6

Take the LCM of the denominators and simplify. LCM = 60. Thus, 60/10 = 6; 6 × 31 = 186. Also, 60/6 =10; 10×17 =170 all divide by 60:

Common factors between the numerator and denominator is 4, therefore 16/4 = 4 and 60/4 = 15.

Therefore the answer is 4/15 in simplest form.
Let distance be s and velocity be v
s = 5t⁴ - 10t² + 6
We know velocity is the change in distance per unit time, so
v = ds/dt
v = 20t³ - 20t
Answer:
7
Step-by-step explanation:
625 - 576 = 49
square root of 49 = 7
One pound bag cost $1.10
