0.25b
B - 0.75b
Answers
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

Answers
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

measure 1 and measure 2 are supplementary. if measure 1 equals (3x - 17) degrees in measure angle two equals (5x + 21) degrees find the value of x
Answers
Answer:
x = 23 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees. Thus, 3x - 17 degrees plus al 5x + 21 deg must equal 180 degrees.
Combining like terms, we get 8x - 4 = 180, or 8x = 184.
Dividing both sides by 8 yields x = 184/8 = 23 = x (measured in degrees)
