Answer: 7, 2 in order.
Step-by-step explanation:
We can combine like terms.
5 - 4 + 1 = 2.
Therefore, 5 - 4 + 7x +1 = 7x + 2.
Thus, the blanks are 7, 2 in order.
Answer:
So there is a 2 in 13 chance to pull out either an ace or king from the deck
Step-by-step explanation:
<span><span>Equations:
</span><span>
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>
<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:
