The correct answer is the first one(a): To get the system B,..., the first equation multiplied by 4...
Explanation:
1. Let us first multiple the first equation in System A with 4, we would get:
4(2x - y) = 4 * 3
=> 8x - 4y = 12 --- (A)
Now add the equation (A) and the second equation of System A:
8x - 4y = 12
3x + 4y = 10
------------------
11x = 22
Hence,
System B:
2x - y = 3
11x = 22
-i
Answer:
347
Step-by-step explanation:
2(3) + 210 = 216
2(3) + 125 = 131
216+131 = 347
X=7
25=DO
35=OG
THESE ARE THE ANSWERS
Answer:
ok so i am just dividing it out the answer would be 0.42185792
Step-by-step explanation:
3.86/9.15=0.42185792
So 11 and a half day so count up how the hours in a day so 24 hr and multiply it by 11 and 0.5 ( bc 0.5 is 1/2)
That’s the first part Ik how to do
