Answer:
first side=40
second side=20
third side=22
Step-by-step explanation:
LET THE SIDES OF THE TRIANGLES BE y
Perimeter=82
first side=2 x y = 2y
second side=y
third side=2 +y
2y + y + 2 + y=82
4y+2=82
4y= 82-2
4y=80
y=80/4
y=20
first side=2y=2(20)=40
second side=y=20
third side= 2 + y= 2 + 20 = 22
1 mile = 1.6km.
so
100 miles x 1.6km = 160.
The number of km between two cities is 160km.
Answer:
18.75=p
s=14.06
b=2.34
Step-by-step explanation:
37.75=b+s+p
-4
33.75=b+s+p
s=3/4p
b=1/6s
33.75=1/6(3/4p)+3/4p+p
33.75=3/20p+3/4p+p
(33.75=18/20p+p)20
675=18p+p)/18
37.50=2p)/2
18.75=p
s=3/4p
3/4(18.75)
s=14.06
b=1/6s
1/6(14.06)
b=2.34
37.75-4=18.75+14.06+2.34=35.15
im missing 50 cents somewhere its wrong but close i think sorry
x is the 1st number, y is the 2nd number, z is the 3d number.
x+y+z = 2
x - y + z= -2
x - z = y +22 -----> x-y-z=22
x+y+z = 2
<u>x - y + z= -2</u>
2x + 2z =0
x + z = 0
x = -z
x - y + z= -2 and x = -z
-z - y + z = -2, y =2
x-y-z=22 and x = -z, and y = 2 -----> x -2 +x = 22 --->2x = 24 ----> x = 12
x= -z -----> z = - 12
Can you post what it says? I could probably help you out.
