Answer: C, y=-4
Step-by-step explanation:
Answer:
y = 
Step-by-step explanation:
9x-4y = 20
<u><em>Given that x = -2</em></u>
<em>Putting in the above equation</em>
9(-2) -4y = 20
-18 - 4y = 20
-4y = 20+18
-4y = 38
<em>Dividing both sides by -4</em>
y = 
y = 
y = 
Answer:
W is 6
L is 19
Step-by-step explanation:
L= 4W - 5
P= 2L + 2W
P= 2(4W-5) +2W
50=8W -10 +2W
60 = 10W
W= 6
L= 19
I think the answer is 54 to question B but don't take my word for it.
