Y=6x 2x+3y=20 solving equation using substitution
RUDIKE [14]

Answer:

x = 1, y = 6

Step-by-step explanation:

y = 6x

2x + 3y = 20

Plug y as 6x in the second equation and solve for x.

2x + 3(6x) = 20

2x + 18x = 20

20x = 20

\frac{20x}{20}= \frac{20}{20}

x = 1

Plug x as 1 in the first equation and solve for y.

y = 6(1)

y = 6

Question 9 Eight wooden spheres with radii of 3 inches are packed snuggly into a cube-shaped box 12 inches on one side. The rema
kobusy [5.1K]
Answer is 823.2 cu.in.
Reason
For the sphere
We know V=4/3 TT r^3
Radius is 3
V=4/3 (3.14) 3^3
V= 4/3 (3.14) 27
V= 113.1 for each sphere
8 spheres x 113.1 = 904.8 cu.in.

For the cubed shaped box
We know v= length x width x height
V= 12 x 12 x 12
V = 1728 cu.in.

Now we take volume of box and subtract volume of spheres to get space filled by packing beads
1728 - 904.8 = 823.2 cu.in.
