1. Since school starts at 7:30, then he wanted to get to school 20 mins early, and he took 70 mins to get ready + to drive to school, we will just use simple math in this problem.
Step-by-step explanation:
7:30 - 20mins (to know what time should he arrive at school)
=7:10 ⇒ is the time Brady should arrive at school)
And since he has 45 mins to get ready and 25 mins to drive to school, 70 mins in total, we will subtract them to 7:10 to know what time should he wake up.
Since 70 mins have 1 hour and 10 mins, we will subtract 1 hour and 10 mins to 7:10 to know the time Brady should wake up.
7:00 - 1hr = 6:00
10mins - 10mins = 0
Therefore, Brady should wake up at 6:00 in the morning to arrive at school 20 mins early.
Answer:
2. Let us add symbols to solve this problem:
Let Judy's sold tickets be variable J
Let Amy's sold tickets be variable J+2 since she sold 2 more than Judy's.
Step-by-step explanation:
The equation will be:
J + J+2 = 12 ⇒ J will be Judy's sold tickets and J+2 will be Amy's sold tickets
2J = 12 - 2 ⇒ Combine the J's and transpose the 2
2J = 10 ⇒ Subtraction property
J = 5 ⇒ Division property and is Judy's sold tickets
Since Judy got 5 sold tickets, then we can use the equation J+2 to solve Amy's sold tickets.
J+2=Amy
5+2=Amy
7=Amy
Therefore, Judy sold 5 ticket shows while Amy sold 7 ticket shows and have a total of 12 sold tickets.
