Step-by-step explanation:
Simplify the following:
(((-3)/4)^5)^2
Multiply exponents. (((-3)/4)^5)^2 = ((-3)/4)^(5×2):
((-3)/4)^(5×2)
5×2 = 10:
((-3)/4)^10
((-3)/4)^10 = (-3)^10/4^10:
(-3)^10/4^10
(-3)^10 = (-1)^10×3^10 = 1×3^10:
3^10/4^10
4^10 = (4^5)^2 = (4×4^4)^2 = (4 (4^2)^2)^2:
3^10/(4 (4^2)^2)^2
4^2 = 16:
3^10/(4×16^2)^2
3^10/(4×256)^2
4×256 = 1024:
3^10/1024^2
3^10/1048576
Answer=3^10 / 2^20
(k+1)x-(2k+3)y-3k-5=0
kx + x - 2ky - 3y - 3k - 5 = 0
(x - 2y) k + (x - 3y) = 3k + 5
therefore
x - 2y = 3
x - 3y = 5
Subtract 2 equations
y = -2
x = -1
Answer:
c. 6 cups
Step-by-step explanation:
The proportion is 1 cup of sugar for 1 dozen cookies (1/1). So if you multiply the denominator by 6 you must multiply the numerator by 6, and 6*1=6. Therefore you need 6 cups of sugar to make 6 dozen cookies.
i believe the answer is y=1/9+3 4/9

Answer:
I don't know if I understood correctly but here is the answer I think could be right.
-5-(-8)=3
2+1=3
