Answer:
(b)
Step-by-step explanation:
graph plotting
when x = -3 , y = 4
when x= -2 , y = 0
when x = -1 , y = -2
when x = 0 , y = -3
when x = 1, y = -3.5
Set up a proportion.
30/6 = 300/x
Cross multiply:
6 * 300 = 30 * x
1800 = 30x
Divide 30 to both sides:
x = 60
So it will take her 60 hours to read the entire book.
In this case, the amount of people that know would be multiplied by two in every minute
1 person - - - - - > 1 person = 2 people know after the first minute
1 person ---------> 1 person
= 4 people know after the second minute
1 person -----------> 1 person
After 3 minutes , all the people will know.
so the answer is 3 minutes
Step-by-step explanation:
In a square,
we know that when diagonals bisect each other it is divided into two equal parts
so
TR = TP
So
PR = x +11 + x + 11
= 2x + 22
And
Both diagonals are equal so
QS = PR
7x - 3 = 2x + 22
7x - 2x = 22 + 3
5x = 25
x= 25 /5
x = 5
Now
PR = 2 * 5 +22= 10 +22 = 32
Answer:
Step-by-step explanation:
To factor out -3/4 out of that equation, multiply and divide by -3/4.
Say ;
=
=
Now, rearranging and making necessary commutations.
=
=
Factoring -3/4 we get an equation without any fractions
= -2x + 3y
