Answer:
7/11
Step-by-step explanation:
7y +6+4y+13=26
firstly collect like terms
7y+4y+6+13=26
11y+19=26
11y=26-19
11y=7
then divide through by 11
y=7/11
the answer to 3806 divided 22 is 173
The answer is 104.
1/4 of 104 is 26, 104 - 26 = 78
78 - 7 = $71
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.
Hope this helps!
