Answer:
time= half hour= 30 min
words = 450
number of words in 30 min= 450
number of words in 1 min= 450/30
number of words in 7 min = 450/30 x 7
= 105 words
Step-by-step explanation:
<h3>5) Find the solution set of the inequality
</h3>
From given,
The solution set is:
6)
<h3>Write an inequality that represents all solutions to
</h3>
From given,
The solution set is:
6)
<h3>What is the solution set of the inequality 6(2 - r) < 18 ?</h3>
From given,
When, we multiply or divide both sides by negative number, we must flip the inequality sign
The solution set is:
7)
<h3>Solve the inequality 4(-3b + 4) - b > -16b + 12</h3>
From given,
The solution set is:
Initial condition:
g+d=700
g=700-d
final condition
d+20=(2g/3)(1/6)
d+20=g/9
9d+180=g, and since g=700-d we can say
9d+180=700-d
10d+180=700
10d=520
d=52, and since g=700-d
g=648
The original number of ducks was 52 and the original amount of geese was 648.
So there were originally (648-52) 596 more geese than ducks.
They would have 2 because is it 10:1 just double it to be 20:2
