dont know wish i could help you :( sorry i hate when i can't answer a question it makes me feel bad
None of these are correct, however of the ones you listed, A would be the most likely to be correct. y is greater than 3... therefore making y a number greater than zero.
Answer:
z=100
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary.
180-80=100
Option B. 8
7+3 = 10
18-10 = 8
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)
