14n-22 is the answer. Use the distributive property.
Theyre both divisible by 3
15n-18= 3(5n - 6)
Answer:
1:50 PM
Step-by-step explanation:
Left school at 10:38 AM,
took them 51 minutes,
38+51=89,
89-60=29,
so when they drove to the museum, it was 11:29 AM.
From here, they stayed at the museum for 1 hour and 26 minutes,
so they stayed at the museum until 12:55 AM since 29+26=55.
Now, it took them 55 minutes to drive back to the school,
so 12:55 plus another 55 minutes,
it's going to be 1:50 PM when Dale's class got back to school.
The best way to solve this one is with a proportion:
(15 steps) / (5 minutes) = (75 steps) / ('x' minutes)
Cross-multiply the proportion: 15 x = 5 x 75
Divide each side by 15 : x = 5 x 5 = <em>25 minutes</em>.
You are correct, and Paul walks very slowly.
Answer:
13

We replace each X with a 3, so
4 + 3 + 3 + 3
which equals to 13
