Answer: D. x=9√3; y=18
Step-by-step explanation:
This is a 30-60-90 special triangle, where we can use the rules to find the value of x and y. (For specific explanation, please look at the attachment below)
-----------------------------------------------------------------------------------------------------
<u>X value</u>
- The shortest side of the triangle that corresponds with [x] is 9 units. This is because it is half of the larger triangle's side length.
- Using the rules, the shortest side is x, then the second short side is x√3
- Substitute value in= x√3=(9)√3=9√3
Y value
- The shortest side of the triangle that corresponds with [x] is 9 units. This is because it is half of the larger triangle's side length.
- Using the rules, the shortest side is x, then the longest side is 2x
- Substitute value in= 2x=2(9)=18
Hope this helps!! :)

Answer:
148-13=135
4x+13= - 3.25
6x+2 = - 0.33
Step-by-step explanation:
1) SIMPLE SUBTRACTION
148
- 13
---------
135
---------
2)
4x+13=0
4x= - 13
x= -13/4
x= - 3.25
3)
6x+2 = 0
6x= -2
x= -2/6
x = -0.33
Answer:
3.4
Step-by-step explanation:
Let the original price of the bag be = P, the selling price =2.89 after a 15% discount,
Then, Selling price= Original price- Discount on original price





Thus, the original price was 3.4.
