Answer:
−7−6
Answer:
The expression
1
÷
1/4
is given. Give a real-life application to explain this expression and then simplify it.
Given a life expression to solve this, when one divide 100 pieces of pencil by 25 which is 1/4 of the entire pencil.
1/1/4=1 x 4/1
=4
Step-by-step explanation:
divide 1 by 1 over 4, then using cross multiply
then we have 1 multiply 4 divided by 1
4 is the final answer
Answer:
P = 0.5Q - 20
Step-by-step explanation:
P = kQ + c
substitute Q = 60 , P = 10 into the equation
10 = 60k + c → (1)
substitute Q = 240, P = 100 into the equation
100 = 240k + c → (2)
subtract (1) from (2) term by term to eliminate c
90 = 180k ( divide both sides by 180 )
= 
= 0.5 = k
substitute k = 0.5 into (1) and solve for c
10 = 60(0.5) + c
10 = 30 + c ( subtract 30 from both sides )
- 20 = c
then
P = 0.5Q - 20
