Answer:
x=1.25
Step-by-step explanation:
Let us replace the number with the variable "x". You will then get this equation:
8x-2=8
Move the -2 to 8 and you would get the equation:
8x=8+2
Simplify:
8x=10
Simplify:
x=10/8
You would then get the answer "x=1.25"
I hope this helps :)
Answer:
x = 30 and y = -34
Step-by-step explanation:
Given the following functions
(1/4)^(x+y) = 256... 1
log₄(x-y) = 3.... 2
From equation 2;
x-y = 4³
x-y = 64
x = 64 + y ... 3
Substitutw 3 into 1
From 1:
(1/4)^(x+y) = 256
(1/4)^(64+y+y) = 256
(1/4)^(64+2y) = 256
Take log₄ of both sides
64+2y log₄ (1/4) = log₄256
-(64+2y) = 4log₄4
-(64+2y) = 4
64+2y = -4
2y = -4 - 64
2y = -68
y = -34
Since
x = 64 + y .
x = 64 - 34
x = 30
Hence x = 30 and y = -34
Isolate "x" on one side of the algebraic equation by dividing the number that appears on the same side of the equation as part of "x."
Answer:
12
Step-by-step explanation:
2x4=8
5x4=20
2x4=8
each side is multipled by 4
Wow I don't get it either but my guess would be 9,6...sorry....
