Answer:
which do you prefer going, English or math class.
Step-by-step explanation:
Length of rectangle = 5 less than 2x width
Perimeter = 146 cm
<u>Equations we will use...</u>
w = width
(2w - 5) = length (l)
perimeter (p) = 2(l + w)
<u>Substitute equation for </u><u>length</u><u> into equation for </u><u>perimeter</u>
p = 2(l + w)
146 = 2((2w - 5) + w) [use distributive prop.]
146 = 4w - 10 + 2w [combine like terms]
146 = 6w -10 [solve for w]
156 = 6w
w = 26 cm
<u>Now substitute width back into the </u><u>equation</u><u> for length...</u>
l = 2w - 5
l = 2(26) - 5
l = 47
Double check to make sure values added up to 146 cm
w + w + l + l = 146
26 + 26 + 47 + 47 = 146
146 = 146
Therefore, the width is 26 cm and the length is 47 cm.
Answer:

Answer:
Step-by-step explanation:
a) +200
b) - 200
c) -500m {well is below sea level.For bellow sea level use - sign}
d) + 5000m
6) a) 12 - 3x
b) (x +10)/7
c) -5y + 16
d) 2m - 11
The equation would be 651=58x+129. Subtract 129 from both sides of the equation. you get 522=58x. Then divide both sides of the equation by 58 to get x alone and you get 9=x. The membership is 9 months. Hope I helped and if you have any questions, just leave a comment.
