|7x-7|+3 = 4x+1 ⇒⇒⇒ add (-3) to both sides

∴ |7x-7| = 4x - 2

According to the absolute rule
∴ 7x - 7 = 4x - 2 OR -(7x - 7) = 4x - 2
7x - 4x = 7 - 2 l 7x - 7 = -4x + 2
 3x = 5 l 7x + 4x = 2 + 7
x = 5/3 l 11 x = 9 ⇒⇒⇒ x = 9/11

∴ x = 5/3 and 9/11

So, the correct answer is option B. 5/3 and 9/11

Marshall drove to work in rush hour traffic, going just 27 miles in 1 hour and 20 minutes. Later that day, he left work early to

iragen [17]

Answer:

The average speed of Marshall is 29.7 mph

Step-by-step explanation:

Given;

distance traveled to work, d₁ = 27 miles

distance traveled back home, d₂ = 27 miles

initial time taken, t₁ = 1 hour and 20 minutes

final time taken, t₂ = 29 minutes

Total distance traveled, d = d₁ + d₂ = 27 miles + 27 miles = 54 miles

Total time taken for the journey, t = t₁ + t₂ = 1 hour + ( 20 mins + 29 mins)

t = 1 hour + 49 mins = 1 hour + 0.817 hour = 1.817 hour

The average speed is given by;

v = total distance / total time

v = 54 miles / 1.817 hour

v = 29.7 mph

Therefore, the average speed of Marshall is 29.7 mph

Please help!!!!!WILL MARK BRAINLIEST. what is the lateral area of the cone?

Ratling [72]

Answer:

Therefore Lateral Area of Cone is 189.97 yd².

Step-by-step explanation:

Given:

Slant height = 12.1 yd

Diameter = 10 yd

∴ Radius = half of Diameter = 10 ÷ 2 = 5 yd

To Find:

Lateral Area of Cone = ?

Solution:

We know that,

$\textrm{Lateral Area of Cone} = \pi\times Radius\times \textrm{Slant height}$

Substituting the given values we get

$\textrm{Lateral Area of Cone}=3.14\times 5\times 12.1\\\\\textrm{Lateral Area of Cone}=189.97\ yd^{2}$

Therefore Lateral Area of Cone is 189.97 yd².

If 3 + 4 7 and 6 + 1 = 7, then 3 + 4 = 6 + 1a. Distributive property . Associative property Transitive property . Commutative pr

Ugo [173]

If 3+4 = 7 and 6+7 = 7 leads to 3+4 = 6+1, then you are using the transitive property. In general the property says that if a = b and b = c, then a = c.
