1 answer:
Kisachek [45]3 years ago

Answer:

At 50 km/hr, she travels a distance of 40 km

At 100 km/hr, she  travels a distance of 160 km

Step-by-step explanation:

The general formula for distance = d = r*t

distance / rate = time

x/50 + y / 100 = 2.4       Multiply by 100

2x + y = 240

x + y = 200

Subtract the two equations

x = 40 km

y = 200 - 40

y = 160 km

So x^3 = x*x*x
f(-2) = (-2)(-2)(-2) = -8

How does algebra affect how people can learn from each other?
pantera1 [17]

Algebra is Faster And Better Than “Basic” Math

Just as multiplying two by twelve is faster than counting to 24 or adding 2 twelve times, algebra helps us solve problems more quickly and easily than we could otherwise. Algebra also opens up whole new areas of life problems, such as graphing curves that cannot be solved with only foundational math skills.
