10% of 26 is 2.60. Now, half of that is 1.30. Add both of them and you get 3.90. Same logic can work for a 20% tip, just double to 10%.
408x or 408 to find the properties to 8x51.
Answer:
(y - 3)(y + 1)
Step-by-step explanation:
Given
(y - 1)² - 4 ← this is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), thus
(y - 1)² - 4
= (y - 1)² - 2²
= (y - 1 - 2)(y - 1 + 2)
= (y - 3)(y + 1) ← in factored form
Answer:
Slope is 2/5x
Step-by-step explanation:
Answer:
65°
Step-by-step explanation:
The sum of the angles of a triangle is always 180°. Meaning, ∠P + ∠Q + ∠R = 180.
(2x-9) + (2x+4) + x = 180
Combine like terms:
5x-5 = 180
5x = 185
x = 37
P = (2x - 9) = 2(37) - 9 = 74 - 9 = 65
