Answer:
$11 approx
Step-by-step explanation:
Given data
Total cost of album= $11.65
Tax= 6%
Let the cost of the album without tax be x
x+ 6/100*x=11.65
x+0.06x=11.65
1.06x=11.65
x= 11.65/1.06
x=10.99
Hence the cost is $11 approx
Answer:
Yes
Step-by-step explanation:
9.8 - (-2.4) = 12.2
22 - 9.8 = 12.2
34.2 - 22 = 12.2
Since it increases by the same amount each time it is arithmetic
<u>x + 4 > 4 + pi</u>
You could subtract 4 from each side.
Then you would have
<em> x > pi </em> .
That looks like a solution to me.
Answer:
∠CDE = 76
Explanation:
1) Find ∠CED
- 180 - 116 = 64
2) Find <em>y</em>
- 4y + 7y + 6 + 64 = 180
- 11y + 70 = 180
- 11y = 110
- y = 10
3) Substitute 10 for <em>y</em>
- 7y + 6
- 7(10) + 6
- 70 + 6
= 76
