Answer:
just letting you know no one can see the photo very well
Step-by-step explanation:
Cd + z = m - cb
cb + z - m = cb
z - m = cb + cb
z - m = c(d + b)
c = (m - z)/(d + b)
Answer:
1/5
Step-by-step explanation:
divide each side by 5
5x/5=1/5
simplify
x/5=1/5
Diagonals of a parallelogram bisect each other
or they intersect each other in the halfway
x+4=3y-11-------------------------equation1
2x-1=y-1-------------------------------equation2
mulitply equation 1 to 2
2x+8=6y-22-----------------------equation3
equation2 - equation3
-9=-5y +21
5y=30
y=6
then x= 3
now PT=2x-1=5
TR=y-1=5
ST=3y-11=7
TQ=x+4=3+4=7
First, you have to combine the 6x and the 10x you do this by subtracting 6x from each side. doing that you get....
-11=4x-51
then, you have to combine the -11 and the -51 you do this by adding 51 to each side. doing that you get....
40=4x
lastly, you need to divide each side by 4 to isolate the variable x. you get...
x=10
