Answer:
Before going to the bakery, Lisa had more than $32.40.
Step-by-step explanation:
Hi there!
Let x be Lisa´s savings.
She brings half of her savings to the bakery and expends $14.20. What is left is more than $2.00. Then:
x/2 - 14.2 > 2
Let´s solve the inequality:
x/2 - 14.2 > 2
Add 14.2 to both sides of the inequality.
x/2 > 2 + 14.2
x/2 > 16.2
Multiply by 2 both sides of the inequality.
x > 32.4
Before going to the bakery, Lisa had more than $32.40.
Answer:

Answer:
2.675 or 107/40
Step-by-step explanation:
- 3/4 x (2 2/5 - 5/6)
- 3/4×107/30
- 107/40
Let "a", "b" and "с" be sides of the triangle ("с" is the longest side). The triangle will be right if a² + b² = c²
A.
a² + b² = 12² + 13² = 144 + 169 = 313
c² = 25² = 625
313 ≠ 625
B.
a² + b² = 36² + 77² = 1296 + 5929 = 7225
c² = 85² = 7225
7225 = 7225 ← right triangle
C.
45, 45, 45 ← this is an equilateral triangle (all angles = 60°)

D.
</span>a² + b² = 45² + 56² = 2025 + 3136 = 5161
c² = 67² = 4489
5161 ≠ 4489
Answer is B
