Answer:
1
Step-by-step explanation:
Column A=X the first value for x is 1
Column B has the x value replaced in the equation 5x+8. 5(1) + 8
Column C has the result, y=13
I don’t feel like doing it but I we’ll tell you how to do it you multiply it by 3 so 6 x 3 equals 18 just in negative do 18 x 3 equal 54 so every other on is a negative it’s Simone
Answer:
157 cm²
Step-by-step explanation:
volume = (1/3) * π * r² * h
volume = (1/3) * π * 5² * 6
volume = (1/3) * π * 25 * 6
volume = (1/3) * π * 150
volume = (1/3) * 471
volume = 157 cm²
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
