Ответ:
68 degrees
Step-by-step explanation:
Angles HJI and JHG are alternate angles, which means that they equal each other. So, we can set them equal:
7x - 16 = 5x + 8
Then, we just solve for x:
7x - 16 = 5x + 8
2x = 24
x = 12
Finally, we plug this value of x into 7x - 16 to find angle HJI:
7x - 16 = 7 * 12 - 16 = 84 - 16 = 68 degrees
Thus, angle HJI is 68 degrees.
Hope this helps!
Ответ:
23.75 + [(0.18)(23.75)]
Step-by-step explanation:
Ellen plans to leave an 18% tip with her $23.75 lunch bill.
Therefore, to determine her total bill, she use the expression
= 23.75 + ( 18% of 23.75 )
= 23.75 + ( 0.18 × 23.75 )
or 23.75 + [(0.18)(23.75)]
So the expression is 23.75 + [(0.18)(23.75)] to determine her total bill.
