8c + 4t = 45
3c + 2t = 20
Modify for elimination: ( multiply 2</span>nd<span> eq by -2)
</span><span>
8c + 4t = 45
-6c + -4t = -40</span></span>

Subtract and solve for "c":
2c = 5
c = $2.50 (cost of one chair)
Solve for "t":
3c + 2t = 20
3(2.50) + 2t = 20
7.50 + 2t =20</span></span>
2t=12.50
<span><span>T= 12.50/2 =6.25
</span>
t = $ 6.25 (cost of one table)</span>
Table = 6.25 each
Chair = 2.50 each
Check:
3(2.50) + 2(6.25) =
7.50 +12.50 = 20
8(2.50) + 4(6.25) =
20.00 + 25.00 = 45.00
Answer:
- The next term of the sequence is represented by the point (5, –64)
Step-by-step explanation:
<u>Note:</u> <em>The first point should be (1, - 4)</em>
According to the points, the sequence is:
- t₁ = - 4, t₂ = 8, t₃ = - 16, t₄ = 32
or
We can observe it is a geometric sequence with common ratio of - 2, as:
- r = 32/ - 16 = - 16/8 = 8/ - 4 = - 2
The following term is:
- t₅ = t₄*r = 32*(- 2) = - 64
The coordinates of same term are:
As we see the correct answer choice is D.
Answer:800cm2
Step-by-step explanation:
Cut the figure into two
Get mesurements (7×8×10)+(5×8×6)
Total= 800
