Answer:
3n + 3
Step-by-step explanation:
Mia is correct
When n= 1 , 3n + 3 = 3*1 + 3 = 3 + 3 = 6
When n =2, 3n + 3 = 3*2 + 3 = 6 + 3 = 9
When n = 3 , 3n +3 = 3*3 + 3 = 9 + 3 = 12
When n = 4, 3n + 3 = 3*4 + 3 = 12 +3 = 15
Answer:
$12.40
Step-by-step explanation:
You can set this up as .20 x 62 which will give you $12.4 or $12.40. You get .20 by converting 20% to a decimal. Also you can simply put 60-20% on a calculator.
The scale factor is 0.6. Then the area of the actual garage is 19.44 m². And dimensions are 3.6 m and 5.4 m.
<h3>What is the scale factor?</h3>
Scale factor means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.
Given
A scale model drawing of a garage is 6 centimeters wide and 9 centimeters long.
The scale model uses a scale in which 3 centimeters represent 1.8 meters.
The scale factor will be
m
Then the dimension of the actual garage will be
Length = 0.6 x 6 = 3.6 m
Width = 0.6 x 9 = 5.4 m
Then the area of the actual garage will be
Area of garage = Length x Width
Area of garage = 3.6 x 5.4
Area of garage = 19.44 m²
Thus, the area of the actual garage is 19.44 m². And dimensions are 3.6 m and 5.4 m.

Answer:
On a coordinate plane, a line goes through (0, 3) and (2, 4) and another line goes through (0, 3) and (0.75, 0).
This answer almost coincide with option C. I suppose there was a mistype.
Step-by-step explanation:
The system of equations is formed by:
–x + 2y = 6
4x + y = 3
In the picture attached, the solution set is shown.
The first equation goes through (0, 3) and (2, 4), as can be checked by:
–(0) + 2(3) = 6
–(2) + 2(4) = 6
The second goes through (0, 3) and (0.75, 0), as can be checked by:
4(0) + (3) = 3
4(0.75) + (0) = 3
The total number of marbles is 15. The probability of picking a blue marble is 6/15. After putting the marble back, the probability of picking another blue marble is probably 1/9.
Answer: the probability of picking two blue marbles in a row is 1/9.
