Answer:
Bill is 25 years old and Jenny is 29 years old
Step-by-step explanation:
Systems of Equations:
J = 4 + B
J + B = 54
Substitute J into the first equation.
4 + B + B = 54
Add like terms.
4 + 2B = 54
Isolate the variable.
4 + 2B = 54
-4 -4
2B = 50
2B/2 = 50/2
B = 25 years old
Plug in B into the second equation of the system.
J + B = 54
J + 25 = 54
Isolate the variable.
J + 25 = 54
-25 -25
J = 29 years old
Check your answer. Pick whatever equation in the system and plug in your answers.
J = 4 + B
29 = 4 + 25
29 = 29
Answer: v = 3/7
Step-by-step explanation:
5 ( 6 - 4v ) = v + 21
30 - 20v = v + 21
30 - 20v - v = 21
30 - 21v = 21
-21v = -30 + 21
-21v = -9
v = -9/-21
v = 3/7

Answer:
AC = 25
Step-by-step explanation:
The product of the near and far distances from C to the circle is the same for each segment. For segment CD, the near and far distances are the same. So, we have ...
CD² = CB·CA
CA = CD²/CB = 15²/9 = 25
The length AC is 25 units.
_____
It seems possible that in some other versions of this question you might be asked to find x. Then you have ...
AB = AC -BC = 25 -9 = 16
3x +1 = 16 . . . substitute for AB
3x = 15 . . . . . subtract 1
x = 5 . . . . . . . divide by 3
Answer:
Rigid Motion and Congruence Two figures are congruent if and only if there exists one, or more, rigid motions which will map one figure onto the other. (thus maintaining the conditions for the figures to be congruent).
