Answer:
The number is -79.
Step-by-step explanation:
Let's set up equation for the given information.
Let the number as 'x'
Negative 1 times the sum of one and seven times a number x could be written as -1(1+7 x).
Now, 6 times the difference of negative seven and a number could be written as
6(-7-x)
Now,
-1(1+7 x) decreased by 6(-7-x) equals 36
So, we can set up equation as
-1(1+7 x)-6(-7-x)=36
Solve the equation for x
-1-7 x-42+6 x=36
Combine like terms
-x-43 =36
Add both sides 43
-x=79
Divide both sides by -1.
x=79

Step-by-step explanation:
9/20 is the probability that Bob's password consists of an odd single-digit number followed by a letter and a positive single-digit number
It is given that bob's password consists of a non-negative single-digit number followed by a letter and another non-negative single-digit number (which could be the same as the first one).
P (odd single digit number ) = ( 5 odd single digits / 10 non-negative single digits) = (5/10) = 1/2
P (positive single digit number ) = (9 positive single digits / 10 non-negative single digits) = 9/10
The total probability is (1/2) (9/10) = 9/20

Below
Step-by-step explanation:
The initial length of the road was 56. 56 is the y-intercept assuming that the graph of this function is a line.
so the equation is:
y= mx+56
m is the slope of the function wich is by how much the function grows.
By analogy, m is the distance added to the road each day.
● y= 3x+56
X is the number of days.
■■■■■■■■■■■■■■■■■■■■■■■■■■
To find the length of the road after 33 days, replace x by 33.
y= 3*33+56 = 155
So after 33 days the road is 155 miles.
