Answer:
14
Step-by-step explanation:
11 - n = -3
-n = -3 - 11 = -14
n = 14
OR
add n to both sides of equation and add 3 to both sides of equation:
11 - n + n + 3 = -3 + n + 3 ----> n = 14
Answer:
Point D
Step-by-step explanation:
To draw a perpendicular bisector between BE, you have take more than half of the length BE on the compass. So, it should be D
C = # of carpenter hrs , b = # of blacksmith hrs
c + b = 30...c = 30 - b
20c + 25b = 690
20(30 - b) + 25b = 690
600 - 20b + 25b = 690
-20b + 25b = 690 - 600
5b = 90
b = 90/5
b = 18 <== hrs worked as blacksmith
c + b = 30
c + 18 = 30
c = 30 - 18
c = 12 <== hrs worked as carpenter
