Solve the equation 18 = 3 + 5x for x.

Answer:

[tex]x = 16[/tex]

Step-by-step explanation:

[tex] \frac{1}{2} (x + 8) - 16 = - 4[/tex]

[tex] \frac{1}{2} x + 4 - 16 = - 4[/tex]

[tex] \frac{1}{2} x + 4 = 12[/tex]

[tex] \frac{1}{2} x = 8[/tex]

[tex]x = 16[/tex]

Answer:

Step-by-step explanation:

[tex]\frac{1}{2}(x + 8 ) - 16 = - 4\\\\\frac{1}{2}*x + 8*\frac{1}{2} - 16 = -4\\\\\frac{1}{2}x + 4 - 16 = -4\\\\\frac{1}{2}x -12 = -4[/tex]

Add 12 to both sides

[tex]\frac{1}{2}x = -4 + 12\\\\\frac{1}{2}x = 8\\[/tex]

Multiply both sides by 2

[tex]x = 8*2\\\\x = 16[/tex]

Answer:

Regular price of 1 pizza = $15 {Assuming discount coupon = $22.5}

Step-by-step explanation:

Let regular non discounted price of 7 pizzas be x

x - 22.5 = 82.5

x = 82.5 + 22.5

x = 105 (Regular Non discounted price of 7 pizzas)

Regular Price of 7 pizzas = 105

Regular price of 1 pizza = 105 / 7 = 15

Answer:$59.50

Step-by-step explanation:

15/100*70= $10.50

$70 - $10.50= $59.50

Answer:

My answer is B and C

Step-by-step explanation:

If you put B in the same dimension, all the sides are equal. Similarly for part C, since the sides are the same, the base of the triangles are the same lengtg

Answer:

x = 6

y = -6

Step-by-step explanation:

x + y = 0 (Multiply by -1)

x + 9y= -48

-x - y = 0

x + 9y= -48

8y = -48

y = -6

x + y = 0

x - 6 = 0

x = 6

Answer:

y=-5x+19 is that what you're looking for bc I don't think you can solve for either variable

Step-by-step explanation:

3.   7:8  [tex]\7\frac{7}{8}[/tex] ,7 to 8

4.  [tex]\frac{100 l}{40 w}[/tex], [tex]\frac{25}{10}[/tex], [tex]\frac{50}{20}[/tex]

5.  [tex]\frac{2 hrs}{120 m}[/tex], unit rate= 60 miles per hour, [tex]\sqrt[2]{120}[/tex]=60

6.  [tex]\sqrt[3]{900}[/tex]= 300, 300x3=900, unite rate= 300km per hour

7.  [tex]\frac{50}{5}[/tex]=[tex]\frac{10\\}{1}[/tex], unit rate for Tim= $10 for 1 hour, [tex]\frac{24}{2}[/tex]=[tex]\frac{12}{1}[/tex], unit rate for Jane= $12 for 1 hour, Jane has the higher rate of pay.

8. [tex]\frac{65}{4}[/tex]=[tex]\frac{16.25}{1}[/tex] , [tex]\sqrt[4]{65}[/tex]= 16.25, unit rate for Jon is 16.25ths of a pushup per minute.

[tex]\frac{45}{3}[/tex]=[tex]\frac{15}{1}[/tex], [tex]\sqrt[3]{45}[/tex]=15, unit rate for Paul is 15 pushups per minute.

Jon can do more pushups in 1 minute

Find the normal approximation to the chance that the face with six spots appears between 9, 10, or 11 times.

The exact chance that the face with six spots appears 9, 10, or 11 times?

my solution; in one roll of the die P(6 spots)=16 In 60 rolls of the die the expected number of times the face with 6 spots appears is given by E(X)=Mean=606=10 times.

SE(6spots)=SD=SQR(606⋅56)=2.8868

Applying the normal approximation to the chance that the face with six spots appears 10 times, I obtain the following: mean = 10

Standard deviation=2.8868

Using the continuity correction of 0.5 the following z-scores are found: z1=(9.5−10)/2.8868=−0.1732 and z2=(10.5−10)/2.8868=0.1732 Subtracting the cumulative probabilities for the two z-scores gives 0.5688−0.4312=0.1376 which is the approximate chance that the face with six spots appears 10 times. find the six spots appears between 9,10, or 11?

The exact chance that the face with six spots appears 10 times is found from

60C10(16)10×(56)50=0.137 find six spots appears 9, 10 or 11 times

Answer:

im not sure if this is right lol but i got 31.18

Step-by-step explanation:

i used cross mutliplication, 35 over x is equal to 55 over 49. then i mutliplied 55 and x which is 55x. then i multiplied 35 and 49, which is 1715. i did 1715 divided by 55 to get rid of x and i got 31.18. hope this helps lol

9514 1404 393

Answer:

  9600

Step-by-step explanation:

392 years is enough time for 392/98 = 4 doublings of the population. If the population doubles 4 times, it will be 2^4 = 16 times its present value

  16 · 600 people = 9600 people . . . in 392 years

2.25 x 4 = 9, and a square has 4 sides, so 2.25 is your answer ! : )

Answer:

Step-by-step explanation:

Average Speed = Total Distance / Total Time

Total Distance = 50+ 70 + 10 + 60 = 190 Miles

Total Time = 1 + 1 + 1/2 + 1/2 =  3 hours

Average speed = 190 / 3 = 63.3 mph

Answer:

58° , 122° , 29°

Step-by-step explanation:

The triangle on the left has 2 congruent sides thus is isosceles.

Then the 2 base angles are congruent, so

∠ 1 = [tex]\frac{180-64}{2}[/tex] = [tex]\frac{116}{2}[/tex] = 58°

∠ 2 and 58° are adjacent angles and supplementary, that is

∠ 2 + 58° = 180° ( subtract 58° from both sides )

∠ 2 = 122°

The triangle on the right has 2 congruent sides and is isosceles

Then the 2 base angles are congruent, so

∠ 3 = [tex]\frac{180-122}{2}[/tex] = [tex]\frac{58}{2}[/tex] = 29°

Answer:

Step-by-step explanation:

Each game costs 2 dollars, so that total spent on games will be 2 * x. We have to add the one time payment of $3, so this will be (2 * x) + 3. Finally, she spends a total of $17, so the final equation will be (2 * x) + 3 = 17.

I'm assuming you've already learned the special properties of a 30-60-90 triangle.

By drawing a 30-60-90 triangle by constructing line BC, and using the special proportions that come from it, we can find that

AB=AC/2=36/2=18

and

BC=AB*[tex]\sqrt{3}[/tex]=[tex]18\sqrt{3}[/tex]

Step-by-step explanation:

Answer:

32 ounces of fruits

Step-by-step explanation:

Given that :

Number of distinct fruits purcahed = 6

Number of ounces of each fruit = 5 1/3

The total ounces of fruits purchased :

(Number of distinct fruits purchased * Number of ounces of each fruit)

6 * 5 1/3 = 6 * 16/3

6 * 16/3 = (16 * 6) / 3 = 96 /3 = 32 ounces of fruits.
