Let s be the length of a section for plants.
Because opposite sides in a rectangle are equal we can state that 7 + 5s = 4 + 6s
Subtract 5s and 4 from both sides to get 7 - 4 = 6s - 5s which simplifies to 3 = s
The length of the wall = 7 + 5 x 3 = 22 ft
Check on opposite side: 4 + 6 x 3 = 22 ft
Answer:
Step-by-step explanation:
X-3y=-5x
(-2y)-3y=15(-2y)
-3y=15
y=-5
Answer:
196 children, 195 adults
Step-by-step explanation:
Use a for adults and c for children
a + c = 391
6a + 1.25c = 1415
Rearrange the first equation to be one variable alone:
a = 391 - c, then replace a in the second equation with that
6(391 - c) + 1.25c = 1415
2346 - 6c + 1.25c = 1415
2346 - 4.75c = 1415
-4.75c = -931
c = 196
There were 196 children admitted.
Now replace that into the original equation:
a + 196 = 391
a = 195 195 adults attended
Answer:
(a-b+2)/3 = c
Step-by-step explanation:
a=b+3c−2
Add 2 to each side
a+2=b+3c−2+2
a+2 = b+3c
Subtract b from each side
a+2 -b =3c
Divide each side by 3
(a-b+2)/3 = 3c/3
(a-b+2)/3 = c
