Answer:
50
Step-by-step explanation:
because the total number of traingle =180 so we have 15 and 35 which equal 50 and the inside angle = 130 and x = 50
Use FOIL and simply, First times First, Outside times Outside, Inside times Inside, Last times Last.
(3x+5)(4x-1)
3x * 4x = 12x²
3x * -1 = -3x
5 * 4x = 20x
5 * -1 = -5
12x² - 3x + 20x - 5
Now simplify by adding -3x to 20x and get:
12x² + 17x - 5
53/100 ÷ 5 can be reduced down to
7

Answer:
The pencil cost $0.05 and the pen cost $1.05.
Step-by-step explanation:
Let, the price of the pencil is $ .
Given that the pen costs a dollar more than the pencil,
So, the price of the pen=$+1.
Therefore, ++1=1.10
, 2+1=1.10
, 2=1.10–1
, 2=0.10
, =0.10/2
, =0.05
The pencil cost $0.05 and the pen cost $1.05.
