r = 3

a_n = a_1(rⁿ⁻¹)

a₁₀ = 7(3¹⁰⁻¹

a₁₀ = 7(3⁹)

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

A book costs $25 .Marilyn bought the book during a sale with 15% discount. How much did she pay for the book
belka [17]
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>

What is the slope-intercept equation of the line below?
Reptile [31]

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.

Brums [2.3K]

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
