Answer:
7. x=3, 8. x=7, 9. x=15.
Step-by-step explanation:
7. If lines m and n are congruent, then angles DCF and CFE are congruent. 15x+3=18x-6. Solve for x. --> 15x+9=18x-->3x=9-->x=3
8.If line m is parallel to line n, then the corresponding angles are congruent. So, 20x+1=22x-13 Solve for x. 20x+14=22x-->14=2x-->x=7.
9. The supplementary angle of 110 is 70. Note that all of the inner angles of a triangle are equal to 180. Form an equation using the the values: (4x+8)+(2x+12)+70=180. Simplify; 6x+90=180. Solve for x: 6x+90=180-->6x=90-->x=15.

Step-by-step explanation:
X + y = 120(being alternate angle)
or,X=120-y
then
2x-y=120
or,2(120-y) - y= 120
240-2y-y=120
y=240-120
y= 120
again,
X=120-y
= 120-120
=0
hence,
X= 0
y= 120
Hello,
The camera is $150
The discount is 30%
First multiply the % by 100 to get a decimal
150 * 0.30 = 45
-----------------------------------------------------------------------------------------------------------------
The Camera now costs $105
The discount price was $45
Hope this helps
