Answer:

−2(4x+3)=5+3x

Step 1: Simplify both sides of the equation.

−2(4x+3)=5+3x

(−2)(4x)+(−2)(3)=5+3x(Distribute)

−8x+−6=5+3x

−8x−6=3x+5

Step 2: Subtract 3x from both sides.

−8x−6−3x=3x+5−3x

−11x−6=5

Step 3: Add 6 to both sides.

−11x−6+6=5+6

−11x=11

Step 4: Divide both sides by -11.

−11x

−11

x=−1

Answer:

A. x= -1

Julian is using a biking app that compares his position to a simulated biker traveling Julian's target speed. When Julian is beh

Gwar [14]

Answer:

11 km/hr.

Step-by-step explanation:

Given information:

Simulated speed = 20/km/h

Time = 15 mins = 1/4 hr = 0.25 hr

Distance Covered as per simulated speed = $20\times \frac{1}{4}=5km$

Position of Julian according to the app = $-2\frac{1}{4}=-2.25$ .

Actual distance covered by the bike is

$Distance= 5 - 2.25 = 2.75km$

Formula for speed:

$\text{Average Speed}=\frac{Distance}{Time}$

$\text{Average Speed}=\frac{2.75}{0.25}$

$\text{Average Speed}=11$

Therefore, the average speed of Julian is 11 km/hr.

Can someone pls help me solved this problem! I need help help can someone help me I will mark you as brainiest! But plz help me!

Vilka [71]

Answer:

The number is less than 3.5

Step-by-step explanation:

Let us break up and convert each individual phrase into its equivalent in an equation.

"Three time" is $3*$

"The difference of a number and three" is (3-x)

"Is greater than" is >

"The number decreased by five" is (x-5)

We can now put all of these parts together to get our equation

$3*(3-x)>(x-5)$

Now, we can simplify this and solve for x

$3*(3-x)>(x-5)\\\\9-3x>x-5\\\\14>4x\\\\\frac{14}{4} >x\\\\\\frac{7}{2}>x\\\\x$

VLD [36.1K]

Sin 40° = h / 80 m
0.6427876 = h / 80 m
h = 0.6427876 · 80 m
h = 51.423 m ≈ 50 m ( to the nearest 10 m )
Answer:
The height of the kite is about 50 m.

If the diameter of the circle above is 20 mm, what is the area of the circle? A. 100 mm2 B. 400 mm2 C. 20 mm2 D. 10 mm2

cestrela7 [59]

Answer:

The answer is 100π.

Step-by-step explanation:

Since the diameter of the circle is 20mm, the radius of the circle is 20/2 = 10mm.

The formula for area of a circle is π*r^2. If we substitute r for 10, we get the final answer as 100π or about 314.16.
