I did this earlier in the day :)
8th grade = 3x = 3(47) = 141 band members.
7th + 8th = 188
7th = x
8th = 3x
x + 3x = 188 ; x = 47 ; 47 + 3(47) = 47 + 141 = 188
4x = 188
4x / 4 = 188 / 4
x = 47 --> 7th grade
8th grade = 3x = 3(47) = 141
To check:
x + 3x = 188 ; x = 47 ;
47 + 3(47) = 188
47 + 141 = 188
188 = 188
Answer: y=-x-1
explanation: swapping the x and y

Answer:
2,914 mm^2
Step-by-step explanation:
The computation of the area of the rectangle is as follows
= Length × width
= 62mm × 47mm
=2,914 mm^2
We simply multiplied the length of the rectangle with its width so that the area of the rectangle could be determined
