At present the sum of Monica's age and daughter's age is 44 years. . After 2 years Monica's age will be three times that if her

sergeinik [125]

Answer:

Monica's age = 34 years

Her daughter's age = 10 years

Step-by-step explanation:

Let Monica's age = x

Let her daughter'sage = y

x + y = 44 -------> equ 1

After 2 years:

Monica's age = x + 2

Her daughter's age = y + 2

x + 2 = 3 * (y+2)

x + 2 = 3y + 6

x = 3y + 6 -2

x = 3y + 4

Put x value in equ 1:

3y + 4 + y = 44

4y = 44 - 4

4y = 40

y = 40/4

y = 10

x = 44 -10

x = 34

What is the solution to 2 log Subscript 9 Baseline (x) = log Subscript 9 Baseline 8 + log Subscript 9 Baseline (x minus 2) x = n

Kaylis [27]

Answer:

$\large\boxed{\large\boxed{x=4}}$

Step-by-step explanation:

The equation to solve is:

$2\log_9 x=\log_9 8+\log_9 (x-2)$

1. <u>On the left-hand side </u>use: "The product of a constant by a logarithm is equal to the logarithm raised to the constant"

Thus, the left-hand side is:

$2\log_9 x=\log_9 x^2$

2. On the <u>right-hand side</u> use "The sum of two logarithms with the same base is the logarithm of the product":

Then, on the right-hand side:

$\log_9 8+\log_9 (x-2)=\log_9 8(x-2)$

3. <u>Make them equal</u>:

$\log_9 x^2=\log_9 8(x-2)$

4. Since the two functions are the same, <u>make the arguments equal</u>:

$x^2=8(x-2)$

5. <u>Solve the equation</u>:

$x^2=8x-16\\\\x^2-8x+16=0\\\\(x-4)^2=0\\\\x-4=0\\\\x=4\leftarrow solution$

Mr. Chin's hotel bill is $143. He leaves 12% of the hotel bill as a tip for the housekeeping service. What is the total amount M

Vlada [557]

First, begin by converting the tip of 12% to a decimal.

.12

Now, multiply that by the total bill.

.12*143=17.16

We now know the numerical value of the tip.

Add the tip to the total bill and get your answer.

143+17.16=160.16

How to decompose a rectangle into two or three smaller rectangles to demonstrate the distributive property?

koban [17]

Answer:

See explanation

Step-by-step explanation:

The distibutive property states that for all real numbers a, b and c

$(a+b)c=ac+bc$

Draw a rectangle with length of (a+b) units and width of c units. The area of this rectangle is

$(a+b)c\ un^2.$

Divide this rectangle into two rectangles: first rectangle with the length of a units and the width of c units and the second rectangle with the length of b units and the width of c units. The area of these rectangles are

$a\cdot c\ \text{and}\ b\cdot c$

These two rectangles together form initial rectangle, so the sum of the area of two smaller rectangles is the area of the bigger rectangle.
