A

since the 3 is outside the radical then \sqrt{9} = 3, hence

x = 9

B

using the law of radicals

\sqrt{a} × \sqrt{b} = \sqrt{ab}

we can separate the factors as

\sqrt{24} × √x^{10} × √y^{5}

= 2\sqrt{6} x^{5}y^{5/2}

C

\sqrt{121} + \sqrt{50} = 11 + 5\sqrt{2}

D

\sqrt{20} × \sqrt{63}

= 2\sqrt{5} × 3\sqrt{7}

= 6\sqrt{35}

The cost of 3 notebooks and 2 pencils is $5.10. At the same prices, the cost of 2 notebooks and 3 pencils is $4.65. What is the
Pepsi [2]

Answer:

$1.95

Step-by-step explanation:

notebook = n

pencil = p

3n + 2p = 5.10

2n + 3p = 4.65

multiply top equation by 2 and bottom by 3

6n + 4p = 10.20

6n +9p = 13.95

subtract bottom equation from the top equation

-5p = -3.75

divide by 5, negatives cancel out

p  = 0.75

sub p into either equation, I chose the original top equation

3n + 2(0.75) = 5.10

3n + 1.50 = 5.10

subtract 1.50 from both sides

3n = 3.60

divide both sides by 3

n = 1.20

p = 0.75

n + p = 1.95 (the fourth option)
