Answer:
96
Step-by-step explanation:
Day 1: 144-8= 136
Day 2: 136-8= 128
Day 3: 128-8= 120
Day 4: 120-8= 112
Day 5: 112-8= 104
Day 6: 104-8=96
Answer:
0.729
Step-by-step explanation:
Greater than
1/6 x 3/2 = 1/4
1/4 > 1/6
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
Subtract these 2 equations,
5x-5x +3y-y = -4-6
2y = -10
y = -5
-5 is your answer.
