Answer:
n = 5
Step-by-step explanation:
Given
3( n - 2) = 9 ( 6 - n)
3n - 6 = 54 - 9n
3 n + 9n = 54 + 6
12n = 60
n = 60/ 12
n = 5
Question:
Two rectangular picture frames have the same area of 45 square inches but have different side lengths. Frame A has a length of 6 3/4 inches, and Frame B has a length of 7 1/2 inches.
Answer:
1. the longer frame (B) has the shorter width
2. the shorter width is 6 3/7 inches, area divided by length
Step-by-step explanation:
The relation between area, length, and width is ...
A = LW
Then the width is ...
W = A/L . . . . . inversely proportional to length
1. Since length and width are inversely proportional (when area is constant), the shorter width will be associated with the longer length. Frame B will have the shorter width.__
2. The width of frame B is ...
W = A/L = (45 in²)/(7 in) = 45/7 in = 6 3/7 in

Answer:
3x + y = -16
Step-by-step explanation:
this is because
5x-2x = 3x
6y-5y = 1y which is written as y
-5 -11 = -16

Answer:
y=4x-1
Step-by-step explanation:
y2-y2/x2-x1
3--9/1--2=12/3=4
now the second part finding b
3=4(1)+b
3=4+b
-1=b
