A. Find 10% of $20, which is $2. Then subtract the sale 20-2, which is $18
B. Since you know the price without taxes is $18, you have to multiply 8.5% of 18, which is $1.53. $18.00 + $1.53= $19.53
So the answer is $19.53

The border will have to be 33b - 8
Step-by-step explanation:
Antoine is making a banner in the shape of a triangle
- He wants to add a decorative border around the edges
- The length of the three sides of the triangle are 9b + 8, 12b - 8 and 12b - 8
We need to find the length of the border
The length of the border is the sum of the lengths of the three sides of the triangle
∵ The length of one side = 9b + 8
∵ The length of another side = 12b - 8
∵ The length of the final side = 12b - 8
- Add the lengths of the 3 sides to find the length of the border
∴ The length of the border = 9b + 8 + 12b - 8 + 12b - 8
- Add like terms
∴ The length of the border = (9b + 12b + 12b) + (8 - 8 - 8)
∴ The length of the border = 33b - 8
The border will have to be 33b - 8

Answer:
20
The strawberry is 3, The watermelon is 3, The peach is 9, and the other one is 5
3+3+9+5=20
Step-by-step explanation:
18+ 5(2x + 5) = 12
18 + 10x + 25 = 12
43 + 10x = 12
10x = 12 -43
10x = -31
x = -3.1
Rewrite
(4)(3.63) * (10^4)(10^-4)
multiply
14.52 * (10^4)(10^-4)
multiplication of the coefficient is the addition of the exponent
so 4 -4 is 0
14.52
