Step-by-step explanation:
2/5×n=18
2n/5=18
2n/2=90/2
n=45
60-3d + 20-6 =4d
74-3d =4d
-3d =4d -74
-7d = -74
D=74/7

Answer:
8x + 4 - z
Step-by-step explanation:
Given the following :
The distance from her house to school is 2x+5 The distance from the school to the park is z If the total distance she was that day is 10x +9 how far is it from the park back to her
Distance from house to school = 2x + 5
Distance from school to park = z
Total distance covered = 10x + 9
Distance from park to house =?
Total distance = (distance from house to school + distance from school to park + distance from park to house)
Let p = distance from park to house
10x + 9 = (2x + 5 + z + p)
10x + 9 - 2x - 5 - z = p
8x + 4 - z
Y=x-3 and Y=1/2x-3/2 and that is ur answer
