Answer:
25
Step-by-step explanation:
Answer:
l = 14 , w = 12
Step-by-step explanation:
2l + 2w = 52 → (1)
l - w = 2 → (2)
multiplying (2) by 2 and adding to (1) will eliminate the w- term
2l - 2w = 4 → (3)
add (1) and (3) term by term to eliminate w
4l + 0 = 56
4l = 56 ( divide both sides by 4 )
l = 14
substitute l 14 into either of the 2 equations and solve for w
substituting into (1)
2(14) + 2w = 52
28 + 2w = 52 ( subtract 28 from both sides )
2w = 24 ( divide both sides by 2 )
w = 12
Answer:
Width = 14 inches
Length = 42 inches
Step-by-step explanation:
Length = 3 x width Width = 1/3 x length
First, construct a equation first using one of my formula on the top:
Length = 3 x width
2y + 6 = 3 ( y - 4 ) Distribute 3 to the values inside the ( )
2y + 6 = 3y - 12 Subtract 2y on both sides so there is only one
variable on one side
6 = y -12 Add 12 on both sides
18 = y
Width = ( y - 4 ) in <u><em>OR </em></u> 18 - 4 or 14 inches
Length = ( 2y + 6 ) in <em><u>OR </u></em> 36 + 6 = 42 inches

Answer:
−10x+3
Step-by-step explanation:
Answer:
13) 4
14) 7
15) 8
How?
21x+6 = 90 by the alternate exterior angles rule so solve and get 4
11x-2=75 by the Corresponding exteriors angles rule so solve and you get 7
8x-4=60 by the vertical angle rule solve and you get 8
Hope this helps :D
