Answer:
48 miles per hour
Step-by-step explanation:
José left Westcliffe on his bicycle riding at an average rate of 8 miles per hour five hours before his father left by automobile. The father overtook José in exactly one hour. This means Jose was riding
5 hours + 1 hour = 6 hours.
Use formula
where
D = distance
r = rate
t = time
In Jose's case,
D = unknown
r = 8 miles per hour
t = 6 hours
Hence,
In Jose's father case,
D = 48 miles
r = unknown
t = 1 hour (father overtook José in exactly one hour)
Hence,
Answer:
x = 98°
Step-by-step explanation:
95 + 53 + (180 - x) = 180
148 + 180 - x = 180
328 - x = 180
328 - x + x = 180 + x
x + 180 = 328
x + 180 - 180 = 328 - 180
x = 98°
Answer:
A)SAS
Step-by-step explanation:
Answer: the number of children tickets sold 265
the number of adult tickets sold 77
Step-by-step explanation:
Let x represent the number of children tickets sold.
Let y represent the number of adult tickets sold.
They charge $5 per ticket for a child and $12 per ticket for an adult. They were sold for a total of $2250. This means that
5x + 12y = 2250 - - - - - - - - - -1
The total number of tickets sold is 342. This means that
x + y = 342
Substituting x = 342 - y into equation 1, it becomes
5(342 - y) + 12y = 2250
1710 - 5y + 12y = 2250
- 5y + 12y = 2250 - 1710
7y = 540
y = 540/7 = 77
x = 342 - y = 342 - 77
x = 265
