x + 2x - x - 1
- Substitute 2 for x into the expression.
(2) + 2(2) - (2) - 1
(2) + (4) - (2) - 1
- Solve from left to right.
- (2 + 4) - 2 - 1 = 6 - 2 - 1
6 - 2 - 1
- Solve from left to right.
- (6 - 2) - 1 = 4 - 1
4 - 1 = 3
<h3>Your answer is 3.</h3>
The first one is d. the second one is c.
Answer:
C, D, F
Step-by-step explanation:

E. 32
F. -32
Answer:
Equations::
4c + 8t = 58
2c + 3t = 23
----------------
Modify for elimination:
4c (4c*1) + 8t (8t*1)= 58
4c (2c*2) + 6t (3t*2)= 46
---------------------
Subtract and solve for "t":
2t (8t-6t) = 12
t = $6 (cost of one table)
-----
Solve for "c":
2c + 3t = 23
2c + 18 = 23
2c = 5
c = $2.50 (cost of one chair)
Answer:
664
Step-by-step explanation:
