Answer: For each of the questions, the numerator gives you the whole number (integer) and the denominator gives you the fraction that it is being multiplied by.
1. It should be 2 times 1/5. Because if you multiply those, you will get back to the fraction of 2/5.
2. It is 5 times 1/12
3. It is 7 times 1/2
Original cost of the book = $25
Percentage of discount got by Marilyn while buying the book = 15%
Amount of discount got by Marilyn while buying the book = (15/100) * 25
= 375/100
= 3.75 dollars
So
The amount paid by Marilyn for buying the book = (25 - 3.75) dollars
= 21.25 dollars
<span>So the total amount paid by Marilyn for buying the book is $21.25.
I hope the procedure for doing this problem is clear to you.</span>
Answer:
Choice A.
Step-by-step explanation:
Slope intercept form of equation is y = mx + b where m is slope and b is y intercept. You can see from diagram that y intercept is -3, and if you count rise/run for slope you go up 2 over 1 so the slope is 2.
Answer: x = 4
Step-by-step explanation:
2(x+1)=10
Distributive properties
a*(b+c)=(a*b)+(a*c)
Using distributive properties
Then
2*(x+1)=(2*x)+(2*1)
2*(x+1)=2x+2
Now, commutative properties
a*b=b*a
Addition is cumulative
a+(-b)=(-b)+a
Therefore applying to 2x+2
2x+2+(-2)=2x+(-2)+2
Then, applying to the equation
2x+2+(-2)=10+(-2), +×-=-
2x+2 -2=10-2
2x=8
Using division properties
ax=b
If a is none zero
Then ax/a=b/a
Therefore x=b/a
Applying that to 2x=8
2x=8. Divide both side by 2 which is none zero
2x/2= 8/2
x=4
Option B
Subtraction Property of equality
