Answer:
844368.7 m
Step-by-step explanation:
We are given that a typical sugar cube has an edge length of 1.00 cm.
We have to find the edge length of the box in meters.
Edge length of sugar cube=1 cm =
(
)
Volume of a sugar cube=
1 mole of sugar=
Volume of 1 unit=
Volume of
units=
Volume of box=1 mole of sugar=
Edge length of box=![\sqrt[3]{6.02\times 10^{17}}=844368.7 m](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B6.02%5Ctimes%2010%5E%7B17%7D%7D%3D844368.7%20m)
Y=1/9(-1)+4
Explanation:
X=-1 and y=8
Answer:
x=4
y=2
Step-by-step explanation:
2x+2y=12
x−y=2
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
2x+2y=12,x−y=2
To make 2x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 2.
2x+2y=12,2x+2(−1)y=2×2
Simplify.
2x+2y=12,2x−2y=4
Subtract 2x−2y=4 from 2x+2y=12 by subtracting like terms on each side of the equal sign.
2x−2x+2y+2y=12−4
Add 2x to −2x. Terms 2x and −2x cancel out, leaving an equation with only one variable that can be solved.
2y+2y=12−4
Add 2y to 2y.
4y=12−4
Add 12 to −4.
4y=8
Divide both sides by 4.
y=2
Substitute 2 for y in x−y=2. Because the resulting equation contains only one variable, you can solve for x directly.
x−2=2
Add 2 to both sides of the equation.
x=4
The system is now solved.
x=4,y=2
Correct choice is B) x=4.
