Answer: x=-1/2
Step-by-step explanation:
2/3x+1/2=1/6
Subtract the 1/2
2/3x=-1/3
Divide by 2/3
x=-1/2

9
noting that | a | = | - a | = a
The distance between the 2 numbers is
| 14 - 2 | = | 12 | = 12
OR
|2 - 14 | = | - 12 | = 12
--------------------------------------------------------------------
10
The distance between the 2 numbers is
| - 10 - 8 | = | - 18 | = 18
OR
| 8 - (- 10) | = | 8 + 10 | = | 18 | = 18
I believe it is c but im not positive
We know that
in the triangle ROA
tan (∡ROA)=12/5
(∡ROA)=arc tan(12/5)---------> 67.38°
in the triangle OPA
(∡POA)=(∡ROA)-------> 67.38°
sin (∡POA)=PA/5-------> PA=5*sin (67.38°)-----> 4.62 units
the answer is
PA=4.62 units
<span>alternative method
</span>in the triangle ROA
RO²=12²+5²-------> RO=13 units
sin (∡ROA)=12/13
in the triangle OPA
(∡POA)=(∡ROA)
sin (∡POA)=12/13
sin (∡POA)=PA/5
12/13=PA/5-------> PA=12*5/13-------> PA=4.62 units
Answer: 10
Step-by-step explanation:
The store wants to make a 20% profit:
Multiply the cost of the toy by 1.20 ( cost plus 20%).
6.25 x 1.20 = $7.50
This means when the toy is sold at 25% off, it needs to be $7.50 to make the 20% profit.
When the item is 25% off, that means it would sell for 75% of the original price.
Now to find what the price needs to be before the 25% off divide the profit price by 75%
7.50 / 0.75 = $10
K = $10
