Answer:
9 = n
Step-by-step explanation:
12 = 6(n – 7)
Divide by 6 on both sides
12/6 = 6/6(n – 7)
2 = n-7
Add 7 to each side
2+7 = n-7+7
9 = n
Answer:
0
Step-by-step explanation:
They are the same set
Hello!
You can solve this algrbraically
2/3 x = -20
Multiply both sides by 3
2x = -60
Divide both sides by 2
x = -30
The answer is B) -30
Hope this helps!
Answer:
x=0
y=8
Step-by-step explanation:
This is a simultaneous equation
So let's solve
y=-8x+8..(1)
y=-8x+8...(2)
Add (1) and (2)
2y=16
Make y the subject of formula by dividing both sides by 2
y=8
Substitute the value for y into (2)
8=-8x+8
Collect like terms
8-8=-8x
0=-8x
Divide both sides by-8
x=0
Therefore x is 0 and y is 8
Depth = Volume / (length x width)
