Answer:
Nico, Raj and Sandra are correct
Step-by-step explanation:
we have

<em>Method 1</em>
Solve for x
That means ----> isolate the variable x
we have

Multiply by 5/2 both sides


subtract 6 both sides


<em>Method 2</em>
Solve for x
That means ----> isolate the variable x
we have

Multiply by 1/2 both sides


Multiply by 5 both sides


subtract 6 both sides


<em>Method 3</em>
Solve for x
That means ----> isolate the variable x
we have

Apply distributive property left side


subtract 2 both sides


Multiply by 5/2 both sides


therefore
Nico, Raj and Sandra are correct
Saw the image.
Given:
Whole wall is 13 2/3 ft by 25ft
4 menus (gray areas) with measurements of 6 ft wide and 7 1/2 ft tall.
Convert mixed fractions into improper fractions.
13 2/3 ft = ((13*3)+2)/3 = 41/3
Area of the Wall = 41/3 ft * 25 ft = (41*25)/3 = 1025/3 ft² = 341 2/3 ft²
7 1/2 ft = ((7*2)+1)/2 = 15/2
Area of the menu = 15/2 ft * 6 ft = (15*6)/2 = 90/2 = 45 ft²
45 ft² x 4 menus = 180 ft²
Area of wall space not covered by the chalkboard paint:
A = 341 2/3 ft² - 180 ft² = 161 2/3 ft²
