Answer:
Sara's number is 28
Step-by-step explanation:
Let's assign Sara's number the variable x and solve this equation using the information provided.
"If you subtract 14 from my number"
x - 14
"and multiply the difference by - 3"
-3(x - 14)
"the result is – 42."
-3(x - 14) = -42
Now we can solve from here for x.
-3(x - 14) = -42
x - 14 = 14
x = 28

Answer:
Small rooms=6
large rooms=10
Step-by-step explanation:
Let the number of small rooms be x
given alexander booked 4 more large rooms than the small rooms.
Therefore the number of large numbers be x+4.
Given each small room can accommodate 3 people.Therefore the total number of people in small rooms are 3x
Given each large room can accommodate 4 people. Therefore the total number of people in large rooms are 4(x+4)
Given total number of people accommodated=58
Total number of guests =number of guests in small rooms + number of guests in large rooms



therefore the number of small rooms =6 and number of large rooms =10
<h3>hello!</h3>
the "sum of" means we add.
So the sum of n and 12 means we add n and 12:-
n+12
or
12+n (both of these expressions mean the same thing)
