<span>Three numbers can be defined as x, y, and z.
x + y + z = 64
y = x+3
z = 2x - 11
.
substitute for y and z
x + (x+3) + (2x-11) = 64
4x -8 = 64
4x = 72
x = 18
.
y = x+3 = 21
z = 2x -11 = 2(18) -11 = 36-11 = 25
.
x + y + z = 18 + 21 + 25 = 64
Correct.
.
Answer: The three numbers are 18, 21, and 25.</span>

Step-by-step explanation:
Let x be the adult weight of puppy B
75% of x =8 pounds
Answer: C
Y=90+6x/x
90 new tools + 6 dollars (x) over x dollars
To find the volume, you cube the edges.
So make it easier, you can cube the numerator and then the denominator.
2*2=4*2=8
3*3=9*3=27
8/27
You cannot simplify it any more.
The volume of the container is 8/27 feet cubes.
Answer: CD=18
Explanation: Use the side-splitter theorem and solve.
1) (3/x)=(4.5/(x+6)), cross multiply and solve for x
2) 6x+36=9x
3) x=12
4) Solve for CD
5) (12)+6=18
