Answer:
DG = 48
Step-by-step explanation:
if line r bisects DG at point E, then point E is midpoint of DG
so DG = 2DE
5z - 7 = 2(2z + 2)
5z - 7 = 4z + 4
5z - 4z = 4 + 7
z = 11
DG = 5z - 7 = 5(11) - 7 = 55 - 7 = 48
Step 1:
Solve one of the equations for either x = or y = .
Step 2:
Substitute the solution from step 1 into the other equation.
Step 3:
Solve this new equation.
Step 4:
Solve for the second variable.
Example 1: Solve the following system by substitution
Substitution Method Example
Solution:
Step 1: Solve one of the equations for either x = or y = . We will solve second equation for y.
solution step 1
Step 2: Substitute the solution from step 1 into the second equation.
solution step 2
Step 3: Solve this new equation.
solution step 3
Step 4: Solve for the second variable
solution step 4
The solution is: (x, y) = (10, -5)
Hope this helps!

6% = .06
“of” = multiply
so 6% of 9000 can be written as .06 x 9000 , which is 540
