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
Answer:
0.4970
Step-by-step explanation:
I might be wrong
20*6=120seconds +3600second in an hour so 3600*4=14400
1210+14400=14520
14520 is the answer I hope this helps!
Answer:
it would be 100
Step-by-step explanation:
if 1=50 and you have 2 then multiple 50 by 2 and that gives you 100
Answer:
It Is 175% Of 88.
Step-by-step explanation:
154 ÷ 88 = 1.75
To Convert A Decimal Into Percent, You Multiply By 100.
1.75 · 100% = 175%
Therefore, The Answer Is 175%.
