Answer:
x = -2, y = 5, z = 7
Step-by-step explanation:
Let these 3 numbers be x, y, and z
x is the first
y is the second
z is the third number.
Then:
x + y + z = 10
2*y - x = 12
x - y + 2z = 7
x = 2y - 12
(2y - 12) + y + z = 10
and
(2y - 12) - y + 2z = 7
so
3y + z = 22
y + 2z = 19
y = 19 - 2z
3*(19 - 2z) + z = 22
57 - 6z + z = 22
57 - 5z = 22
35 = 5z
z = 7
y = 19 - 2*7 = 19 - 14 = 5
x = 2y - 12 = 2*5 -12 = 10 -12 = -2
Charlie has 5 times as many stamps as Ryan then C = 5R.
R + C = 1608.
So we plug in for C
R + 5R = 1608
6R = 1608
R = 268
Now find Charlie by plugging in and we get
268 + C = 1608
C = 1340
Lets check our answer
1340 = 5(268) yup we are right.
Answer:
C. The expression cannot be factored.
