Answer:
The number is 3.5.
Step-by-step explanation:
1) Form an equation.
8x-5= 23
2) Add 5 to both sides.
8x= 28
3) Divide both sides by 8.
X= 3.5
Let C = cost to rent each chairLet T = cost to rent each table
4C + 8T = 73
2C + 3T = 28
Multiply the 2nd equation by (-2) and then add the equations together
4C + 8T = 73
-4C - 6T = -56
2T = 17T = 17/2 = 8.5
Plug this in to the 1st equation to solve for C
4C + 8(17/2) = 73
4C + 68 = 73
4C = 5C = 5/4 = 1.25
So the cost to rent each chair is $1.25 and the cost to rent each table is $8.50
Answer: 
<u>Do Keep Change Flip (KCF)</u>
Keep: 5/6
Change: ÷ into ×
Flip: 3/1 into 1/3
Your new problem should be: 5/6×1/3
<u>Multiply</u>
5/6×1/3=5/18
Answer:
the answer is 15 because you have to do the problem in the parentheses first then multiply by 5
<u>Sin is -sqrt 2/2 cos is sqrt2/2 and tan is -1</u>
