Answer:

Necklace cost $144 and bracelet cost $48

Step-by-step explanation:

call x is the price of necklace, y is the price of bracelet

because necklace cost 3 time as much as the bracelet

=> 3x = y

A necklace and a bracelet cost $192

=> x + y = 192

=>set of equations

3x = y and x+y = 192

x= 3y and 3y + y = 192

=> y = 48 and x = 3 . 48 = 144

Answer: -22


Step-by-step explanation:

In the first question, we can simplify 2√8 to 4√2, making it :

(√10 + 4√2)(√10 - 4√2)

When you FOIL, √10(√10) = 10, and 4√2 * -4√2 = -32. The others cancel each other out. So -32 + 10 = -22.

inessss [21]
Pick any two points
(0, 3), (-1,9)
Find slope (y2-y1)/(x2-x1)
(9-3)/(-1-0) = 6/-1 = -6
Y = -6x + b
Plug in a point
3 = 0 + b, b= 3
Final equation: y = -6x + 3

( 3 x 2 ) ^ 4 x 3 ^ -3 / 2 ^ 3 x 3 =<br><br> Simplify the exponential expression
Korvikt [17]

Answer:

2

Step-by-step explanation:

\frac{(3*2)^4*3^{-3}}{2^3*3}

we start simplifying by removing the parenthesis

Multiply the exponents inside the the parenthesis

3^4  * 2^4

\frac{3^4*2^4*3^{-3}}{2^3*3}

Now we apply exponential property

a^m * a^n = a^ (m+n)

3^4 * 3^-3 = 3^ (4-3) = 3^1

3 or 3^1  are same

\frac{3^1*2^4}{2^3*3^1}

3^1 at the top and bottom so we cancel it out

\frac{2^4}{2^3}

we apply log property . a^m / a^n = a^m-n

Now subtract the exponents

2^(4-3) = 2^1 = 2

What is your reading rate if you read 2/3 of a chapter in 3/4 an hour expressed in chapters per hour
andrew-mc [135]
¾ an hour is 45 minutes

So to have your answers you need to do a cross product :

45 minutes —> 2/3 of a chapter
60 minutes —> X of a chapter

((2/3) • 60) / 45

40/45 = 8/9

Answer : You read 8/9 of a chaper per hour! :)
