Answer: A student who owns a cell phone is more likely to have brought a personal device than not to have brought one.
Step-by-step explanation:
Hola!
x = 9
Explicación:
Resta 11 de ambos lados
5x + 11 - 11 = 56 - 11
Usted obtiene:
5x = 45
Divide ambos lados por 5
5x/5 = 45/5
Usted obtiene:
x = 9
English:
Subtract 11 from both sides
5x + 11 - 11 = 56 - 11
You get:
5x = 45
Divide both sides by 5
5x/5 = 45/5
You get:
x = 9
Answer: 51m²
Step-by-step explanation:
To solve this type of problem , you first of all consider the diagram asba complete block.The diagram is a complete block or rectangle upon which a triangle is superimposed. To find the area of the shaded region , just find the area of the whole block and removed the area of the triangle that was superimposed.
Now, let move to the real work
Area of the whole block
= length × breadth
= 7m × 9m
= 63m²
Step ii,
Area of the right angle triangle
= (1/2)bh
= 1/2 × b × h
Now to get the dimensiona of the triangle, we need to do some deductions. Since the widths of the triangle is 9m, therefore, the height of the triangle wil
= 9m - 3m
= 6m.
h = 6m.
Since the length of the triangle is 7m, therefore, the base of the triangle will be
= 7m - 3m
= 4m.
Step iii, to find the area of the triangle now , we applied the formula.
Area = 1/2 × 6 × 4
= 12m².
Now to find the area of the shaded region , we carry out subtraction
Area = 63m² - 12m²
= 51m².
