Answer:
linear equation has two variables doesn't involve any power
quadratic equation involves one of the variables raised to the second power.
Step-by-step explanation:
A <u>linear equation</u> in two variables doesn't involve any power higher than one for either variable. It has the general form Ax + By + C = 0, where A, B and C are constants. ... A <u>quadratic equation</u>, on the other hand, involves one of the variables raised to the second power.
Okay and what do you need to find??
Answer:
1.248
Step-by-step explanation:
6/5 ⇒ 1.2
25/24 ⇒ 1.041666666666667 or approximately 1.04
1.2 * 1.04
= 1.248
Answer:
4.5 x 10 ^9
Step-by-step explanation:
D = vt
Distance traveled by train
d = 55t
Distance traveled by plane
d = 285t
Total distance
d = 1020
So, you do:
distance traveled by plane + distance traveled by train = total distance
(55t) + (285t) = 1020
Solve for t
t = 3 hours
t is the time traveled by each so 3 hrs traveled by train and 3 hrs traveled by plane
Total time = 3 + 3 = 6 hours
