Your equation is 3(8-4)+2*5.5
you want to follow PEMDAS
Parenthesis
Exponents
Multiplication
Division
Addition
Subtaction
so first you will solve the parenthesis (8-4) = 4
put it into your exquation
3(4)+2*5.5
now the next thing we have is multiplication
3(4) = 12
2*5.5 = 11
now plug it into the equation
12+11=?
now you just do the addition
your answer should be
A. 23
Answer:
Speed of plane in still air = 825 km/h
Step-by-step explanation:
Given:
Speed of plane with the wind is 145 km/h faster than what it would have with still air.
Speed of plane with wind = 970 km/h
To find speed of plane in still air.
Solution:
Let speed of plane in still air be =
km/h
Thus speed of plane with wind would be given as =
km/h
Speed of plane with wind is given =970 km/h
So, we have:

Solving for
.
Subtracting both sides by 145.

∴
km/h (Answer)
Thus, speed of plane in still air = 825 km/h
11/8 is 1.375 that times 12 is 16.5 so 16.5 dollars
An equation is said to have a constant of proportionality if 'x' is a multiple of 'y' or 'y' is a multiple of 'x'.
