if your wanting to know how far the diver will be down you do 240+25 which is 265
265-80=185 (cause the diver swims up)
185+12+30 =227
227-16 =211
the deep see diver is at 211 meters below the surface
The equivalent expression for the given expression is 28p + 14q + 21r.
<h3>What is an equivalent expression?</h3>
An expression that gives the same value as the original expression when the same value of a variable is substituted is said to be an equivalent expression.
An equivalent expression is simplified to the original expression by using the distributive property.
<h3>What is distributive property?</h3>
The distributive property is
a(b + c) = ab + ac
<h3>Calculation:</h3>
The given expression is 7(4p + 2q + 3r)
Applying the distributive property,
7(4p + 2q + 3r) = 7(4p) + 7(2q) + 7(3r)
⇒ 28p + 14q + 21r
Thus, the equivalent expression for the given expression is 28p + 14q + 21r.

Answer:
Part A) The equation that represent the situation is
Part B) The value of n is
Part C) The equation is and the solution is
Step-by-step explanation:
Part A) A number is increased by 54. The sum is then divided by 9. The result is 21. Write an equation to represent the description above. Use n for the number
Let
n-----> the number
we know that
The linear equation that represent this situation is equal to
Part B) Find the value of n
we have
solve for n
Multiply by 9 both sides
Subtract 54 both sides
Part C) Choose two numbers and use them to do the following:
Write an equation that shows your first number added to n equal to your second number. Solve your equation for n
I choose 35 and 60
Solve for n
Subtract 35 both sides
