Answer:
Step-by-step explanation:
the perimeter is : p = 2(x+y)..... x : width y : length
you have the system ; 2(x+y) = 252.......(1)
x = (2/7) y ...........(2)
y > x ....(3)
Substitute x = (2/7) y into (1) and simplifiy and solve for y :
(2/7) y + y = 126
(2y+7y)/7 = 126
9y = 882
y = 98 m ( the length )
Answer:
Step-by-step explanation:
angle:: x
complemet: 90-x
supplement: 180-x
Equation:
180-x = 4(90-x)+60
180-x = 360 -4x + 60
3x = 240
x = 80 degrees (the angle)
90-x = 10 degrees (the complement)
180-x = 100 degrees (the supplement)
200=7p or 7p=200 I hope I could help you with your problem
Answer:Repeating Decimal
Step-by-step explanation:
Answer:
1 56/100 or 1 28/50 or 1 13/25 or 14/9.
Step-by-step explanation:
1.5555555556 rounded is 1.56 which is 1 56/100 which can be made in improper form and made in simpler form.
10x = 15.55555555.
x = 1.55555555.
10x - x is 15.55555555 − 1.555555555.
9x is 14.55555555.
Divide both sides by 9/
x is 14/9.
