Equivalent expressions are defined as algebraic expressions which give the same resulting expression. An algebraic expression (or) a variable expression is defined as a combination of terms by the operations such as addition, subtraction, multiplication, division.

Here, given expression

$\sqrt{2/x^2} X \sqrt{x^2/18}$

= $\sqrt{2 X x^2/18x^2}$

= $\sqrt{1/9}$

= 1/3

Thus, the equivalent expression to given expression is 1/3.

Cara and John collect baseball cards.Cara has 12 times as many baseball cards as John.Together they have 117 cards.How many card

enyata [817]

Answer:

Cara:108

Step-by-step explanation:

John: x number of cards

Cara: 12 times x number of cards(she has 12 times more cards than John)

Cara+John=117 cards

$12 \times x + x = 117 \\ 13x = 117 \\ x = \frac{117}{13} \\ x = 9$

Cara has 12×9 cards, so she has 108 cards.

Hope this was helpful :)

Answer:

Hi there!

Your answer is;

i) 400% of 240

240 is 100%

× 4

960= 400%

ii) 40% of 240

100% = 240

/100

1% = 2.4

× 40

40% = 96

iii) 4% of 240

100% is 240

/100

1% = 2.4

× 4

4% = 9.6

iv) .04% of 240

100% = 240

/100

1% = 2.4

/100

.01% = .024

× 4

.04% = .096

b) the patterns is that all these numbers equal sometime 96. Each of these have a different decimal place, but have the same actual numbers.

c) 4000% = 240

take the pattern:

400% is 960

Scale it up to 4000 by 10

400% is 960

× 10

4000% is 9600

Hope this helps!
