Answer: 24
Step-by-step explanation:
Amount of bushels of peas collected = 42
Fraction that'll be sent to market = 3/7
Fraction that'll be kept = 1 - 3/7 = 7/7 - 3/7 = 4/7
The number of bushels that'll be kept will be:
= Fraction that'll be kept × Total number of bushels collected
= 4/7 × 42
= 24
Answer:
it`s not true that for every person, if the person is happy, the person has a large income/there are people that are happy and doesn't have large incomes
Step-by-step explanation:
let be x the group of people in the world
let be I(X)=x has a large income
let be H(x)=x is happy
Having a large income is not a necessary condition for a person to be happy.
¬∀x, H(x)-->I(x)
<em>it`s not true that for every person, if the person is happy, the person has a large income</em>
∃x / H(x)^¬I(x)
<em>there are people that are happy and doesn't have large incomes</em>
Problem 1
We replace every copy of x with 4c and simplify like so:
f(x) = 8 - 5x
f(4c) = 8 - 5*4c
f(4c) = 8 - 20c is the answer
This is equivalent to -20c+8.
====================================================
Problem 2
Same idea as before, but this time we'll plug in x = 2-k
Each x gets replaced with (2-k)
f(x) = 8 - 5x
f(2-k) = 8 - 5(2-k)
f(2-k) = 8 - 10 + 5k
f(2-k) = -2 + 5k
This is the same as saying 5k - 2.
====================================================
Problem 3
The steps are similar to earlier.
f(x) = 8 - 5x
f(4p+3) = 8 - 5(4p+3)
f(4p+3) = 8 - 20p - 15
f(4p+3) = -7-20p
This is the same as writing -20p - 7.
