Answer:
x = 2
y = -3
z = 4
( 2 , -3, 4 )
Step-by-step explanation:
x + y + z = 3 ---- i
x – y =5 ---- ii
y - z = -7 ---- iii
ii + iii
x - z = -2 ---- iv
i + ii
2x + z = 8 --- v
iv + v
3x = 6
x = 2
x=2 substitute for v
z = 4
x =2 substitute for ii
y = -3
Answer: I think 13
Step-by-step explanation:
60 hundreds means 6000 = 6 thousands;
So, 10 · x = 6000;
x = 600;
600 means 6 hundreds;
Finally, 10 times as many as 6 hundreds is 60 hundreds or 6 thousands.
Lets say x is quantity
65%x+25%(600-x)=45%of 600
.65x+.25(600-x)=.45*600
.65x+150-0.25x=270
0.4x=120
x=300ml
Answer:
(16 x^8 - x^3 + 6)/(2 x^3)
Step-by-step explanation:
Simplify the following:
(64 x^8 - 4 x^3 + 24)/(8 x^3)
Factor 4 out of 64 x^8 - 4 x^3 + 24:
(4 (16 x^8 - x^3 + 6))/(8 x^3)
4/8 = 4/(4×2) = 1/2:
Answer: (16 x^8 - x^3 + 6)/(2 x^3)
