Can someone help me with this ONE question? Write an equation.. and solve for X

matrenka [14]

Answer:

Equation: 720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)

x=17

Step-by-step explanation:

A 6 sided polygon is 720° degrees

so

720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)

Simplify

720=(8x+5x+7x+6x)+(−1+110+36+116+19+−2)

Combine like terms:

720=26x+278

flip equation:

26x+278=720

subtract 278 from both sides

26x=442

divide by 26 both sides:

x=17

Hope this helps.

Priya measured the length of lizard to be 11 cm. The actual length is 12 cm. Find the % error.

Aleksandr [31]

Answer:

8.33%

Step-by-step explanation:

Formula for percent error:

$|\frac{observed value - expected value}{expected value} | * 100%$

Using this formula, we get:

$|\frac{11-12}{12} |* 100 = \frac{100}{12} = 8.33$
