Answer:
no they are not
Step-by-step explanation:
Firstly you have to reduce the 4 variables to a double system of equation with only 2 variables.
Let's say, first we have to eliminate Z:
Take 1st & 3rd equation & multiply each term of the 1st by (- 1). One done you add up the 1st & the 3rd & you will get:
5W - 4x + 2y = - 18
Follow the same methodology to find another equation without z. Once done you will have a system of 2 equation with 2 variable easy to solve,
At the end you will find:
w = -3
x = -2
y = -1
z = 3
The answer is 3 because if you were to round 2.9 the next whole up from that is 3
Answer:x=10/3
Step-by-step explanation:
Answer:
1.67miles/hour
Step-by-step explanation:
Speed of the penguin = Distance/Time taken
Given
Distance = 1/3 mile
Time = 1/5 hour
Substitute the given data into the speed formula;
Speed = (1/3)/(1/5)
Speed = 1/3 * 5/1
Speed = 5/3
Speed = 1.67miles/hour
Hence the penguin speed in mi/hr is 1.67mi/hr
