Answer:
Width = 18 inches
Length = 59 inches
Step-by-step explanation:
The length of a rectangle is five more than triple the width. If the perimeter is 154 inches, what are the dimensions
Perimeter of a rectangle = 2L + 2W
The length of a rectangle is five more than triple the width.
L = Length = 5 + 3W
W = Width
If the perimeter is 154 inches, what are the dimensions
Hence,
154 = 2L + 2W
154 = 2(5 + 3W ) + 2W
154 = 10 + 6W + 2W
Collect like terms
154 - 10 = 8W
144 = 8W
W = 144/8
W = 18 inches
Length = 5 + 3W
Length = 5 + 3(18)
Length = 5 + 54
Length = 59 inches
No, the y-intercept is the value of y at the point where a line crosses the y-axis.
Answer:
if im understanding right the answer should be x = -1
Step-by-step explanation:
5x - 11 = 3x - 9
subtract 3x
2x -11 = -9
add 11
2x = -2
divide by 2
x = -1
Answer:
-11
Step-by-step explanation:
−5−6
=−5−6
=−5+−6
=−11
