<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution of the equation,
x + 21 = 62
x = 62 - 21
x = 41
Hence, the solution of the equation is 41.

Answer:
The first question is A) P + 0.15P + 0.08P
The second question is B) 1.09P
Step-by-step explanation:
The cost of the dinner is the amount for the dinner, P plus the tax, 8% of P, which is 0.08P, plus the 15% tip, which is 0.15P
The cost of the car is P, or $15, plus the tax is 9%, or 0.09P
P + 0.09P = 1.09P
Answer:
64.8°
Step-by-step explanation:
A
Please see attached a rough sketch for your reference
Step one:
Given data
the distance you are standing from the building represent the adjacent =400ft
and the height of the building represents the opposite= 850ft
Step two:
Required is the angle of elevation
applying SOH CAH TOA
Tan ∅= opp/adj
Tan ∅= 850/400
Tan ∅=2.125
∅=Tan-1(2.125)
∅=64.8°
The angle of elevation 64.8°
