Answer:
15 feet
Step-by-step explanation:
Perimeter = All outside lengths added together
We know that the shape is a square, and squares have 4 sides.
So, divide 60 by 4.
60 / 4 = 15.
The length of one side is 15 feet.
Step-by-step explanation:
open brackets and work out
2(3x - 4) = 2x + 12
6x - 8 = 2x + 12
4x = 20
x = 5
AB = 3(5) - 4 = 11
AC = 2(5) + 12 = 22
BC = 7(5) - 2 = 35 - 2 = 33
AC:BC = 22:33 = 2:3
Answer:
y = 10
x = 25
Step-by-step explanation:
From the U theorem the sum of these two angles 120+2x+y = 180
same goes for the bottom part too:
2x-y+140 = 180 now add two equations up
120+2x+y + 2x-y+140 = 180 + 180 add like terms (-y will eliminate +y)
4x + 260 = 360 subtract 260 from both sides
4x = 100 divide both sides by 4
x = 25 since the sum of 2x-y+140 = 180 we can find the value of y by replacing x with 25
2*25 - y + 140 = 180
50 - y + 140 = 180 add like terms
190 - y = 180 subtract 190 from both sides
-y = -10 and y = 10
Answer:
Step-by-step explanation:
ok so, we know they washed 34.
x-5=Trucks washed [19.5-5=(14.5)]
x=cars washed (19.5)
x+x-5=34
2x-5=34
+5 +5
2x=39
divide 2 both sides
x=19.5
To check work: 19.5+14.5=34!
Hope this helps :)
