Answer: " b = 3 ⅕ ; or, write as: 3.2 .
_____________________________________
Given: "A = (1/2) * b * h " ;
↔ A = (b * h) / 2
2A = (b*h) ;
2A/ h = b ;
↔ b = (2A) / h ;
Given A = 48 ; and h = 30 ; Plug in these values; and solve for "b" ;
→ b = (2*48) / 30 ;
= 96/30 ;
= (96÷6) / (30÷6) ;
→ b = 16/5 ; = 3 <span>⅕ ; or, write as: 3.2 .

Answer:
The line of reflection is 
Step-by-step explanation:
In reflection, the image and the pre-image are the same distance from the line of reflection.
We choose any pair of corresponding points and find the midpoint.
The points (-1,3) and (3,3) are corresponding points.
The x-coordinate of the midpoint is 
Hence the line of reflection is
Answer:
Step-by-step explanation:
Billy and Maria mow lawns. Billy earned $15 the first day and $20 every day after that. This means the if Billy mowed lawns for x days after the first day, the total amount earned by Billy would be
15 + 20x
Maria earned $10 the first day and $25 every day after that. This means the if Maria mowed lawns for y days after the first day, the total amount earned by Maria would be
10 + 25y
To determine how much each earns after 15 days, it becomes
For Billy, x = 15
Amount earned = 15 + 20×15 = $315
For Maria, y = 15
Amount earned = 10 + 25×15 = $385
Maria earns more than Billy
