Step-by-step explanation:
I'm not sure where a is supposed to be in this equation, but I'm going to assume it's supposed to be written as either 3a x 4b = 54, or 304b = 54a. If it's something else, let me know, but I'll just answer these two for now.
1. 3a x 4b
So we know that b is equal to 9. Therefore, we can rewrite
as
To get rid of a multiplier on one side, divide both sides by the number you want gone. I'll use 4(9), which equals 36.
Then we can divide by 3 to get
0.5 isn't a viable answer, so I'll try the second interpretation.
2. 304b = 54a
This one is a bit easier. All we need to do is divide both sides by 54 to get
304 x 9 = 2736
2736/54 = 50.66...
Again, not a viable answer. Please edit your question to include a and I'll give it another shot!
Answer:
(4, 5 )
Step-by-step explanation:
Moving 7 left is in the x direction and means subtract 7 from the x- coordinate
Moving 5 down is in the y direction and means subtract 5 from the y- coordinate, that is
(11, 10 ) → (11 - 7, 10 - 5 ) → (4, 5 )
2(2x) + 2(10x + 24) = 360
use the distributive property
4x + 20x + 48 = 360
combine like terms
24x + 48 = 360
subtract 48 from both sides
24x = 312
divide both sides by 24 to isolate the variable x
x = 13
The correct answer is A. 13.
Answer:
2
Step-by-step explanation:
-3 log₂ (-n + 10) = -16+7
-3 log₂ (-n + 10) = -9
log₂ (-n + 10) = -9/-3
log₂ (-n + 10) = 3
-n + 10 = 2^3
-n + 10 = 8
n=2
Inverse means the opposite. it's a bit confusing..I believe it's either C or D.
