Answer:
The expression is 3(v - ut)
Step-by-step explanation:
* Lets explain how to solve the problem
- There are some words we can change them to mathematics symbols
# Add ⇒ +
# Subtract ⇒ -
# Multiply ⇒ ×
# Divide ⇒ ÷
- Ex:
# Add x and 6 ⇒ x + 6
# Subtract 7 from y ⇒ y - 7
# Multiply 5 by m ⇒ 5 × m = 5m
# Divide n by 2 ⇒ n ÷ 2 = n/2
*<em> Lets solve the problem</em>
- We want to write an expression for the sequence of operations
described below
- Multiply u by t, subtract the result from v, then triple what you have
* <em>Lets make these operations</em>
- Multiply u by t
∴ u × t = ut
- Subtract the result from v
- Means take ut from v, so v will come first
∵ The result is ut
∴ v - ut
- Triple what you have
∵ Triple means multiply by 3
∵ we have (v - ut)
∴ 3(v - ut)
* The expression is 3(v - ut)
