7.	Solve for x :i. 4x - 7 - (x+4) = 3x + 4 - (2x - 1)ii. 17 ( 2 - x) - 5 ( x + 12 ) = 8
Answer» SoluTion: (1) 4x - 7 - (X + 4) = 3x + 4 - (2x - 1) → 4x - 7 - x - 4 = 3x + 4 - 2x + 1 → 4x - x - 3x + 2x = 4 + 1 + 7 + 4 → 2x = 16 → x = 16/2 → x = 8 (2) 17 ( 2 - x) - 5 ( x + 12 ) = 8 → 34 - 17X - 5x - 60 = 8 → -22x + 34 - 60 = 8 → -22x = 8 + 26 → x = -32/22 → x = -16/11

7.

Solve for x :i. 4x - 7 - (x+4) = 3x + 4 - (2x - 1)ii. 17 ( 2 - x) - 5 ( x + 12 ) = 8

Answer»

SoluTion:

(1) 4x - 7 - (X + 4) = 3x + 4 - (2x - 1)

→ 4x - 7 - x - 4 = 3x + 4 - 2x + 1

→ 4x - x - 3x + 2x = 4 + 1 + 7 + 4

→ 2x = 16

→ x = 16/2

→ x = 8

(2) 17 ( 2 - x) - 5 ( x + 12 ) = 8

→ 34 - 17X - 5x - 60 = 8

→ -22x + 34 - 60 = 8

→ -22x = 8 + 26

→ x = -32/22

→ x = -16/11

Check whether (x-2) is a factor of x3- 2(x)2-x+2

Answer»

Answer:

Hope it will help you mark me as brainleast or thanks me please..

Step-by-step explanation:

To CHECK that x−2 is the factor of x 3 −2x 2 −5x+4

Then the value of x−2=0, so x=2.

So, PUT x=2 in expression, we get

f(x)=x 3 −2x 2 −5x+4

f(2)=(2) 3 −2(2) 2 −5(2)+4

⇒f(2)=8−2×4−5×2+4

⇒f(2)=8−8−10+4

⇒f(2)=−6

Remainder is not zero when x−2 DIVIDED polynomial x 3 −2x 2 −5x+4.

Thus x−2 is not a factor of polynomial x

3 −2x 2 −5x+4.

If (3a+5)° and (2a-25)° are supplementary angles, then smaller angle is :a) 30°b) 55°c) 80°d) 85°[ PLZ EXPLAIN IT ALSO ]

Answer»

ANSWER:

(B) 55°

Step-by-step explanation:

(3a+5)°+(2a-25)°=180°(Supplementary Angles)

3a+5+2a-25=180°

5a-20=180°

5a=180+20

5a= 200°

a=200/5

a= 40°

(3a+5)°= 40×3+5

=120°+5

= 125°

(2a-25)°= 40×2-25

= 80°-25

= 55°

Therefore, the correct option is (b) 55°.

35.	First solve then verify the questionDude this is the 6th time i am posting this questions no one is helping me kindly help me i am in huge trouble
Answer» PART 1: (i) Solve 2x + 2 = 4. ⇒ 2x + 2 = 4 ⇒ 2x = 4 - 2 ⇒ 2x = 2 ⇒ x = 1 ∴ The value of x is 1. Now, Let's verify it. (By verifying we are basically substituting the value of x in 2x + 2 = 4, and SEE if the LHS = RHS) ⇒ 2x + 2 = 4 x = 1, therefore: ⇒ 2(1) + 2 = 4 ⇒ 2 + 2 = 4 ⇒ 4 = 4 ⇒ LHS = RHS Hence verified. ---------------------------------- Part 2: (ii) Solve x + 4 + x - 2 = 0. ⇒ x + 4 + x - 2 = 0 ⇒ 2x + 4 - 2 = 0 ⇒ 2x + 2 = 0 ⇒ 2x = -2 ⇒ x = -2/2 ⇒ x = -1 Verification. ⇒ x + 4 + x - 2 = 0 x = -1, therefore: ⇒ -1 + 4 + (-1) - 2 = 0 ⇒ 3 + (-3) = 0 ⇒ 3 - 3 = 0 ⇒ 0 = 0 ⇒ LHS = RHS Hence verified. ---------------------------------- Part 3: (iii) Solve x ÷ 6 = 3 ⇒ x ÷ 6 = 3 ⇒ x = 3 × 6 ⇒ x = 18 Verification. ⇒ x ÷ 6 = 3 x = 18, therefore: ⇒ 18 ÷ 6 = 3 ⇒ 3 = 3 ⇒ LHS = RHS. Hence verified. ---------------------------------- Part 4: $\sf (iv) \ Solve \ \ \dfrac{3x - 3}{2x + 4} = 3$ $\sf \Longrightarrow \dfrac{3x - 3}{2x + 4} = 3$ TRANSPOSING (2x + 4) to the RHS we get: ⇒ 3x - 3 = 3(2x + 4) ⇒ 3x - 3 = 6x + 12 ⇒ 3x - 6x = 12 + 3 ⇒ -3x = 15 ⇒ x = 15/-3 ⇒ x = -5 Verification: $\sf \Longrightarrow \dfrac{3x - 3}{2x + 4} = 3$ x = -5, therefore: $\sf \Longrightarrow \dfrac{3(-5) - 3}{2(-5) + 4} = 3$ $\sf \Longrightarrow \dfrac{-15 - 3}{-10 + 4} = 3$ $\sf \Longrightarrow \dfrac{-18}{-6} = 3$ We know that -6 × 3 = -18. $\sf \Longrightarrow 3 = 3$ ⇒ LHS = RHS Hence Verified. ---------------------------------- Part 5: (v) Solve 0.9x - 3 = 6 ⇒ 0.9x - 3 = 6 ⇒ 0.9x = 6 + 3 ⇒ 0.9x = 9 Multiplying both sides by 10 we get: ⇒ 9x = 90 ⇒ x = 90/9 ⇒ x = 10 Verification: ⇒ 0.9x - 3 = 6 We know that x = 10, therefore: ⇒ 0.9(10) - 3 = 6 ⇒ 9 - 3 = 6 ⇒ 6 = 6 ⇒ LHS = RHS Hence Verified. ----------------------------------

First solve then verify the questionDude this is the 6th time i am posting this questions no one is helping me kindly help me i am in huge trouble

Answer»

PART 1:

(i) Solve 2x + 2 = 4.

⇒ 2x + 2 = 4

⇒ 2x = 4 - 2

⇒ 2x = 2

⇒ x = 1

∴ The value of x is 1.

Now, Let's verify it.

(By verifying we are basically substituting the value of x in 2x + 2 = 4, and SEE if the LHS = RHS)

⇒ 2x + 2 = 4

x = 1, therefore:

⇒ 2(1) + 2 = 4

⇒ 2 + 2 = 4

⇒ 4 = 4

⇒ LHS = RHS

Hence verified.

----------------------------------

Part 2:

(ii) Solve x + 4 + x - 2 = 0.

⇒ x + 4 + x - 2 = 0

⇒ 2x + 4 - 2 = 0

⇒ 2x + 2 = 0

⇒ 2x = -2

⇒ x = -2/2

⇒ x = -1

Verification.

⇒ x + 4 + x - 2 = 0

x = -1, therefore:

⇒ -1 + 4 + (-1) - 2 = 0

⇒ 3 + (-3) = 0

⇒ 3 - 3 = 0

⇒ 0 = 0

⇒ LHS = RHS

Hence verified.

----------------------------------

Part 3:

(iii) Solve x ÷ 6 = 3

⇒ x ÷ 6 = 3

⇒ x = 3 × 6

⇒ x = 18

Verification.

⇒ x ÷ 6 = 3

x = 18, therefore:

⇒ 18 ÷ 6 = 3

⇒ 3 = 3

⇒ LHS = RHS.

Hence verified.

----------------------------------

Part 4:

$\sf (iv) \ Solve \ \ \dfrac{3x - 3}{2x + 4} = 3$

$\sf \Longrightarrow \dfrac{3x - 3}{2x + 4} = 3$

TRANSPOSING (2x + 4) to the RHS we get:

⇒ 3x - 3 = 3(2x + 4)

⇒ 3x - 3 = 6x + 12

⇒ 3x - 6x = 12 + 3

⇒ -3x = 15

⇒ x = 15/-3

⇒ x = -5

Verification:

$\sf \Longrightarrow \dfrac{3x - 3}{2x + 4} = 3$

x = -5, therefore:

$\sf \Longrightarrow \dfrac{3(-5) - 3}{2(-5) + 4} = 3$

$\sf \Longrightarrow \dfrac{-15 - 3}{-10 + 4} = 3$

$\sf \Longrightarrow \dfrac{-18}{-6} = 3$

We know that -6 × 3 = -18.

$\sf \Longrightarrow 3 = 3$

⇒ LHS = RHS

Hence Verified.

----------------------------------

Part 5:

(v) Solve 0.9x - 3 = 6

⇒ 0.9x - 3 = 6

⇒ 0.9x = 6 + 3

⇒ 0.9x = 9

Multiplying both sides by 10 we get:

⇒ 9x = 90

⇒ x = 90/9

⇒ x = 10

Verification:

⇒ 0.9x - 3 = 6

We know that x = 10, therefore:

⇒ 0.9(10) - 3 = 6

⇒ 9 - 3 = 6

⇒ 6 = 6

⇒ LHS = RHS

Hence Verified.
