If you add the digits in a two-digit number and multiply the sum by 7, you get the original number. If you reverse the digits in the two-digit
number, the new number is 18 more than the sum of its two digits. What is the original number?
A. 42
B. 24
C. 64
D. 46
Е. 36
The answer is A. 42
Solution:
Let x= ones digit, y=tens digit
1st condition (original number) : 7(x+y)=10y + x
2nd condition (new number by reversing the digits): 18+x+y=10x+y
simplifying:
1st condition: 6x=3y
2nd condition: x=2
substituting x=2 to 6x=3y
y=4
Answer:
42

75b
0.25b
B - 0.75b
Answer:
try b-0.75b
Step-by-step explanation:
Cost of the bag after the discount is given by the equation A = B - 0.75B
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of the bag be represented as B
Now , the equation will be
The discount percentage of the bag is = 75 %
So , the cost of the bag after discount = cost of the bag - ( cost of the bag x discount percentage )
Substituting the values in the equation , we get
The cost of the bag after discount = B - ( 75/100 ) B
On simplifying the equation , we get
The cost of the bag after discount = B - 0.75B
Hence , the equation is B - 0.75B

Diego is building a patio deck. The length of the deck is (x + 8) feet. The width of the deck is (x + 3) feet. What is the simplest form expression for the perimeter of the deck?
Answer:
(4x + 22) feet
Step-by-step explanation:
Diego is building a patio deck. The length of the deck is (x + 8) feet. The width of the deck is (x + 3) feet. What is the simplest form expression for the perimeter of the deck?
A patio deck = Rectangular in shape
Hence:
The formula for the Perimeter of a rectangle = 2L + 2W
Where
L = Length
W = Width
The length of the deck is (x + 8) feet. The width of the deck is (x + 3) feet.
The perimeter of the deck =
2(x + 8)feet + 2(x + 3)feet
= (2x + 16) feet +( 2x + 6)feet
= (2x + 2x + 16 + 6) feet
= (4x + 22) feet
Therefore, the perimeter of the deck = (4x + 22) feet

How would you write y = 2x - 3 in function notation? *
Answer:
f(x)=2x-3
Step-by-step explanation:
To write an equation in function notation change the y to an f(x). Then, if you plug something in for x also replace it in f(x). For example, if x=3 then the equation would be f(3)=2(3)-3.

Answer:
1/2
Step-by-step explanation:
you the x and the y intercepts!
the X intercept is (4,0) and the Y intercept is (0,-2)
and in having those two intercepts, it made solving for the slope a whole lot easier!!!
heres what you do:
-2 - 0 = -2
0 - 4 = -4
and that can be simplified down to 1/2 :D
