what does x equal
well do 180/-9=-20
then you need to do -20+18 whic equals -2.
there you go

Answer:
15.50h + 50 > 400
Step-by-step explanation:
Given;
Weekly salary = $50 per week
Additional pay = $15.50 per hour
The variable h represent the number of hours worked per week
The total amount earn per week is;
Weekly salary + total additional pay per week
50 + 15.50h
To earn more than $400 this week, the total amount earned in a week must be greater than 400;
15.50h + 50 > 400
Solving the equation we have;
15.50h > 400-50
h > (400-50)/15.50
h > 22.58 hours per week.
Answer:
1/12 of a mile.
Step-by-step explanation:
1. Find a common denominator. In this instance, we can use the denominator of 12 because both 3 and 4 are multiples of 12.
2. Multiply each fraction (numerator and denominator) to convert them.
1/3(4/4) = 4/12
1/4(3/3) = 3/12
3. Subtract.
4/12-3/12 = 1/12

Step-by-step explanation:
Answer:
The number of days the number will be greater than 60 is 45.
Step-by-step explanation:
Since there are 80 total numbers and a number of the day can be repeated, then there is the same chance each day of picking one of the numbers. There are 20 numbers greater than 60 between 1 and 80. So, the chances of picking a number greater than 60 each day is 20/80, or 1/4 (25%). This probability is the same each day and we would take the total number of school days (180) multiplied by this probability to get our predicted number of days the number would be greater than 60 during the school year. 180 x .25 = 45.
