Help No Google answer

Answer»

Step-by-step explanation:

1) a)

12 = 2x 2x 3

20 = 2 x2 x 5

CF = 2 x2

RF = 3 x 5

So,

LCM = cf x Rf

= 4 x 15

= 60 answer

( Do all by same way )

2) a)

C.F from both term = 3 x 7

RF from both term = 2 x 5 x 5

So,

hlo answer this and take 40 points the numerator of a fraction is 6 less than the denominator. if 3 is added to the numerator, the fraction is equal to 2\3,find the original fraction

Answer»

GIVEN :–

• The numerator of a fraction is 6 less than the DENOMINATOR.

• If 3 is added to the numerator, the fraction is equal to ⅔ .

TO FIND :–

• ORIGINAL fraction = ?

SOLUTION :–

• Let the denominator 'x' .

• So , Numerator = x - 6

▪︎ ACCORDING to the QUESTION –

$\\ \implies\sf \dfrac{(x - 6) + 3}{x + 3} = \dfrac{2}{3} \\$

$\\ \implies\sf \dfrac{x - 3}{x + 3} = \dfrac{2}{3} \\$

$\\ \implies\sf 3(x - 3)= 2(x + 3) \\$

$\\ \implies\sf 3x - 9= 2x + 6 \\$

$\\ \implies\sf 3x - 2x= 9+ 6 \\$

$\\ \implies\sf x= 9+ 6 \\$

$\\ \implies \large{ \boxed{\sf x=15 }}\\$

• HENCE –

$\\ \implies \sf \: original \: \: fraction = \dfrac{15 - 6}{15} \\$

$\\ \implies \large{ \boxed{ \sf \: original \: \: fraction = \dfrac{9}{15}}} \\$

10.

0.555555......... in p/q form

Answer»

Answer:

1. 0.555555...

Let x be = 0.555555... --------(1)

Multiplying both sides by 10 since 1 number is repeating.

10 × x = 10 × 0.555555...

10x = 5.555555... --------(2)

Subtract EQUATION (1) from equation (2)

10x - x = 5.5555555... - 0.555555...

9x = 5

x = 5/9

p/q form of 0.555555... is 5/9

2. 0.3636363636...

Let x be = 0.36363636... --------(1)

Multiplying both sides by 100 since 2 numbers are repeating.

100 × x = 100 × 0.36363636...

100x = 36.36363636... --------(2)

Subtract equation (1) from equation (2)

100x - x = 36.36363636... - 0.36363636...

99x = 36

x = 36/99

x = 12/33

x = 4/11

p/q form of 0.36363636... is 4/11

3. 3.888888...

Let x be = 3.888888... --------(1)

Multiplying both sides by 10 since 1 number is repeating.

10 × x = 10 × 3.888888...

10x = 38.888888... --------(2)

Subract equation (1) from equation (2)

10x - x = 38.88888... - 3.88888...

9x = 35

x = 35/9

p/q form of 3.88888... is 35/9

Answer»

Answer:

I hope it help you.

Step-by-step explanation:

For a parallelogram,

▶Opposite sides are equal.

GIVEN,

Area of parallelogram = 35 cm^2.

Length of QR = RT + TQ

Length of QR = 7

We know ,

Area of parallelogram = BASE × height

Base = PQ = ?

Height = QR = 7cm

So,

35 = base ×7

35/7 = base

5CM = base

For ΔPQT

Base = PQ = 5cm

Height = QT = 4cm

Area of TRIANGLE = 1/2 × base × height

Area of triangle = 1/2 × 7 × 4

Area of triangle = 1/2 × 28

Area of triangle =14 cm^2

Answer» Answer: n = 36 Step-by-step EXPLANATION: n/2 - 3n/4 + 5n/6 = 21 LCM of 2,4 and 6 = 12 = 6n/12 - 9n/12 + 10n/12 = 21 = 6n - 9n + 10n/12 = 21 = 7n/12 = 21 = 7n = 21 X 12 = 7n = 252 = n = 252/7 = n = 36

40.

What is n÷2-3n÷4+5n÷6=21

Answer»

Answer:

n = 36

Step-by-step EXPLANATION:

n/2 - 3n/4 + 5n/6 = 21

LCM of 2,4 and 6 = 12

= 6n/12 - 9n/12 + 10n/12 = 21

= 6n - 9n + 10n/12 = 21

= 7n/12 = 21

= 7n = 21 X 12

= 7n = 252

= n = 252/7

= n = 36

If 2x+3x eqal to 14,2x-3y equal to 2,find the value of xy

Answer»

Answer:

xy = 8

Step-by-step explanation:

2x + 3y = 14 ..............(1)

2x - 3y = 2 .............(2)

ADDING (1) and (2) we get

4x = 16

x = 4.

Now, putting x = 4 in any equation ( (1) or (2) )

We get y = 2.

Now xy = 4 x 2 = 8.
