find the value of x

Answer:

9x-12

Step-by-step explanation:

3*x = 3x

3*-4= -12

3x - 12 = 12x

12x-3x = 9x

9x-12

Answer:  x = -4/3

Step-by-step explanation:

3(x−4)=12x

Step 1: Simplify both sides of the equation.

3(x−4)=12x

(3)(x)+(3)(−4)=12x  (Distribute)

3x+−12=12x

3x−12=12x

Step 2: Subtract 12x from both sides.

3x−12−12x=12x−12x

−9x−12=0

Step 3: Add 12 to both sides.

−9x−12+12=0+12

−9x=12

Step 4: Divide both sides by -9.

-9x/-9 = 12/-9

x = -4/3

Answer: x=7 or undefined

Step-by-step explanation:

We can't write x=7 in slope intercept form, since it doesn't have an actual slope or y-intercept. You could put undefined, since the slope is undefined.

Step-by-step explanation:

Step one:

given

sample space

7 cans of apple​ juice,

6 cans of grape​ juice,

6 cans of orange​ juice, and

4 cans of mango juice

Sample size= (7+6+6+4)

                       = 23

Step two:

Required

The probability of randomly selecting three cans of mango juice in succession

Note: we are selecting without replacement

let the probability of selecting three cans of mango juice be

the first selection is= 4/23

The second = 3/22

the third= 2/21

[tex]P(x)= 4/23*3/22*2/21[/tex]

[tex]P(x)= \frac{4*3*2}{23*22*21} \\\\P(x)= \frac{4}{23*11*7}\\\\P(x)= \frac{4}{1771}[/tex]

Answer:

The elevation of the rest stop is 37.5 feet above sea level.

Step-by-step explanation:

Given that the elevation at the top of the hill is 127 feet above sea level and The valley floor is 52 feet below sea level.

So, the total length from the top of the hill to the valley floor

[tex]l= 127+52 = 179[/tex] feet

So, length of halfway [tex]= l/2=179/2=89.5[/tex] feet ...(i)

Assuming that the stop for rest, the halfway between the top of the hill and the valley floor, is at x feet above sea level.

So, the length between the stop position and the valley floor [tex]= 52 +x[/tex] feet.

As the stop position is at half-way, so by using equation (i), we have,

[tex]52 + x = 89.5 \\\\\Rightarrow x =89.5-52 \\\\[/tex]

[tex]\Rightarrow x=37.5[/tex] feet

Hence, the elevation of the rest stop is 37.5 feet above sea level.

Answer: A- 3 3/10 feet

Step-by-step explanation:

Multiply 5 and 1/2 by 3/5 to get 3 and 3/10 feet. I prefer decimals so you could use 5.5 x 0.6 and get 3.3. It's the same thing but if it's in fractions you should multiply by using fractions.

Answer:

z=7

Step-by-step explanation:

72°+(8z-8)°+(9z-3)°=180° (a triangle contains 180° and vertical angles are equal)

(8z-8)°+(9z-3)°=180°-72°

17z°-11°=108°

17z°=108°+11°

17z°=119°

z°=119°/17°

z°=7°

z=7

A quadratic function is written as ax^2 + bx + c

Where the first term is raised to the 2nd power and the second term includes the x variable.

Answer:

I think the answer is 1500

Step-by-step explanation:

 Elevation of the road at 5 miles from the starting point is 1250 ft.

Given in the question,

Two triangles formed by a road are ΔADE and ΔABC (As shown in the figure attached).

Since, ∠A ≅ ∠A (Reflexive property)

           ∠AED ≅ ∠ACB (right angles)

            ΔADE ~ ΔABC (By A-A property of similarity)

In these similar triangles, corresponding sides will be proportional.

[tex]\frac{AB}{BC}=\frac{AD}{DE}[/tex]

[tex]\frac{8}{2000}=\frac{5}{DE}[/tex]

[tex]DE=\frac{5\times 2000}{8}[/tex]

      [tex]=1250[/tex] miles

   Therefore, elevation of the road at 5 miles from the starting point will  be 1250 ft.

    Option (B) will be the answer.
