The answer to your question is X = -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)
Answer:
x r 1.26 cm
Step-by-step explanation:
This can easily be solved by congruence.
Both triangles have the same proportions.
9.8 : 8.8 = (2 + 9.2) : (x + 8.8)
Because these are proportional, we can use and write this as if they were fractions.
9.8 / 8.8 = (2 + 9.2) / (x + 8.8)
multiply crosswise, gives:
9.8 * (x + 8.8) = (2 + 9.2) * 8.8
9.8 * x + 9.8 * 8.8 = (11.2) * 8.8
9.8 * x + 86.24 = 98.56
9.8 * x = 98.56 - 86.24
9.8 * x = 12.32
Divide left and right of the = sign by 9.8 gives,
x = 12.32 / 9.8
x = 1.2(571428)
x = 1.26 cm
