Answer:
53
Step-by-step explanation:
Given: The sum of two digit number is 8
Reversing the digit will get us number 18 less than the original.
Lets take x as tenth digit of our number and y as unit digit of our number.
As given sum of digit is 8
∴ 
∴ 
- equation 1
We also know that reversing the digit will get us number 18 less than the original.
∴ 
Now, lets put the value of y from equation 1
⇒ 
⇒ 
⇒ 
∴ 
Next, substituting the value of x in equation 1
⇒ 
∴ 
∴ The original number is 53, sum of the digit is 8 and if we reverse the digit of the number, we get 35, which is 18 less than the original number.

Answer:
B. 13 small bags and 12 large bags
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the number of small bags.
y is the number of large bags.
The Tuesday morning delivery consists of 25 bags
This means that 
, that is 
Bunyan Farm sells 3 pound and 5 pound bags of onions. Total of 99 pounds.
This means that 
Since
So 13 small bags and 12 large bags.
Answer:
(-2,7) reflects to (-2,-7)
(3,9) reflects to (3, -9)
(7,2) reflects to (7,-2)
(-3,9) reflects to (-3,-9)
Step-by-step explanation:
in reflection across the x-axis the x value of the coordinate stays the same and the y value is negated to show it been reflected
Answer:
The cost increase for each square of carpet by 12.
Step-by-step explanation:
The given function is
It is a slope intercept form of the line
Where m is the slope and b is y-intercept.
Therefore the slope of given function is 12 and the y-intercept is 50.
It means the initial ot fixed cost of the carpet is 50 and the cost increased by 12 for each square of carpet.
