Let
x------> amount of money Theo has
y------> amount of money Denise has
z------> amount of money Rudy has
we know that
x+y+z=$45-----> equation 1
x=5+y-----> equation 2
y=11+z----> equation 3
substitute equation 2 in equation 1
[5+y]+y+z=45-------> 2y+z=40-----> equation 4
y=11+z----> equation 3
2y+z=40-----> equation 4
resolves the equations system
using a graph tool
see the attached figure
the solution is
y=17
z=6
x=5+y----> x=5+17----> x=22
the answer is<span>
Denise has $17</span>

Answer:
1) 12 - 8/3 = ((12*3)-(8))/3 = 28/3
2) 10/ (4/7) = (10/1)*(7/4) = 70/4
3) 12/5 + 4/6 = ((5*4)+(12*6))/(5*6) = 46/15
Answer:
x = 8 or x = -8
Step-by-step explanation:
Solve for x over the integers:
-abs(x) = -8
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides by -1:
abs(x) = 8
Hint: | Eliminate the absolute value.
Split the equation into two possible cases:
Answer: x = 8 or x = -8
