Answer:

X = [tex]\frac{13}{16}[/tex]

Step-by-step explanation:

2 (4-8x) + 6 = 1

Multiply parentheses by 2

8 - 16x + 6 = 1

add (8 + 6)

14 - 16x = 1

Move constant to right and change its sign

-16x = 1 -14

Calcualte te difference

-16x = -13

divide bot sides by -16

x = [tex]\frac{13}{16}[/tex]

The given equation 2(4-8x)+6=-1, distribute the 2, combine like terms, and then isolate x to find that x = 15/16.

The student has provided an equation 2(4-8x)+6=-1 and requires help solving for x. To solve this equation, we first distribute the 2 across the terms in the parenthesis:

8 - 16x + 6 = -1.
Combine like terms:
14 - 16x = -1.
Subtract 14 from both sides:
-16x = -15.
Divide both sides by -16:
x = 15/16.

Therefore, the solution is 15/16.

Complete Question: Solve the equation 2(4-8x)+6=-1 using Method 2 (interpreting expressions as a single quantity).

Answer:

Question1: 58660

Question 3: 7244

Step-by-step explanation:

Question 1: My 5 is worth 50,000 means the number will start with 5 and will be between 50,000 and 60,000, thus will have 5 digits in total

My 8 is worth 8,000 means the next number is 8

One of my 6s is worth 60 means there is more than one 6. One 6 is worth 60 and the other is 10times as much so 600. The other digit is a 0. So those 3 together are 660.

The entire number is 58660

Question 3: The number has 4 digits:

My 7 is worth 7000 so the number will be between 7,000 and 8,000.

My 2 is worth 200 so.

One of my 4s is worth 40. So this means there is another 4.

The other number is 1/10 of 40, which is 4.

The total is 7244

Answer: ∠1 = 109°    ∠2 = 71°

Step-by-step explanation:

If the two angles form a linear pair, then their sum is 180°

  ∠1      +     ∠2     = 180°

(5x + 9) + (3x + 11) = 180

              8x + 20  = 180

              8x          = 160

                x          = 20

∠1 = 5x + 9

    = 5(20) + 9

    = 100   + 9

    = 109

∠2 = 3x + 11

     = 3(20) + 11

     =    60  + 11

     =         71

  CHECK:

∠1   + ∠2 = 180°

109° + 71° = 180°

     180°   = 180°  [tex]\checkmark[/tex]

Answer:

Speed of first car = 30 km/h and speed of second car = 55 km/h

Step-by-step explanation:

Speed = distance/time

Given: distance travelled by one car = 120 km

Distance travelled by second car = 220 km

Now let speed of first car be x km/h.

∴ Speed of second car = (x + 25) km/h  (∵ One car travels 25 km\h faster than another)

Now, if the time is constant, then ratio of distance to speed of first car will be equal to the ratio of distance to speed of another car. e.g.,

[tex]\frac{distance\ travelled\ by\ first\ car}{speed\ of\ first\ car} = \frac{distance\ travelled\ by\ second\ car}{speed\ of\ second\ car}[/tex]

[tex]\frac{120}{x} = \frac{220}{x+25}[/tex]

[tex]220x = 120 (x +25)[/tex]

[tex]220x = 120x + 3000[/tex]

[tex]100x = 3000[/tex]

[tex]x = 30[/tex]

∴ Speed of first car = 30 km/h

Speed of second car = (30 + 25) = 55 km/h.

Answer:

140 miles.

Step-by-step explanation:

The distance the car travels on 1 litre= 120/30 = 4 miles.

So the distance for 35 litres = 4 * 35 = 140 miles.

The car's fuel efficiency is calculated as 4 miles per liter based on the given data. Using this, it is determined that the car can travel 140 miles on 35 liters of petrol.

To calculate how far a car can travel on 35 liters of petrol, we need to determine its fuel efficiency, which is the distance it can cover per unit volume of fuel. Based on the given that the car can travel 120 miles on 30 liters of petrol, we can write an equation to represent the car's fuel efficiency:

Fuel efficiency = Distance/Volume of fuel = 120 miles / 30 liters = 4 miles per liter

Now that we have the car's fuel efficiency, we can find out how far it can travel on 35 liters of petrol:

Distance on 35 liters = Fuel efficiency × Volume of fuel = 4 miles/liter × 35 liters

Distance on 35 liters = 140 miles

Therefore, the car can travel 140 miles on 35 liters of petrol.

There are 11 halves in 5 and 1/2.

A fraction is a number that is represented as a quotient where the numerator is divided by the denominator.

Two equal parts of one whole thing. In fraction form, half can be written as 1/2.

We have to find the number of halves in 5 and 1/2. We know that there are 2 halves of one whole thing. For 5 as a whole number, the number of halves would be,

5 × 2 = 10. Then, there are 10 halves in 5. Notice that there is one more 1/2 in 5 and 1/2. We can conclude that there are 10 + 1 = 11 halves in 5 and 1/2.

Therefore, there are 11 halves in 5 and 1/2.

Answer:

The company decided to increase the price by $9.60, or by 48%.

Step-by-step explanation:

To measure the price difference in dollars is simple, just subtract the old price from the new one:

[tex]29.60 - 20 = 9.60[/tex]

Divide the price change by the old price to find the price increase in percentage:

[tex]9.60 \div 20 = 0.48 \\ 0.48 \times 100\% = 48\%[/tex]

Answer:

Step-by-step explanation:

The last time the customer bought the product it was $20. The price has increased by $9.60.

Subtract the old price from the new one

$29.60 New Price- $20 Old Price=$9.60

Now Divide the Price Change amount of $9.60 by the Old Price $20

$9.60/$20=0.48

The length of one side of the cube is 4 feet.

In Geometry, a Cube is a solid three-dimensional figure, which has 6 square faces, 8 vertices and 12 edges.

The given volume of the cube is,

V = 64 cubic feet

Let a be the length of each side of the cube.

Therefore volume V of the cube is given as,

V = (side)³

or, V = a³

Since, V = 64 cubic feet

Therefore,

a³ = 64 cubic feet

Taking cube root both the side we get,

∛a³ = ∛64 cubic feet

or, a = ∛64 cubic feet

Since, ∛64 = 4

Therefore,

a = 4 feet

which is the length of one side.

Thus, the length of one side of the cube is 4 feet.

Answer: 27 can go in completely to 70 twice, or, if you want an exact decimal, 2.5925 (...it goes on and on) times

Step-by-step explanation: what you have to do is divide, 70 divided by 27. What “go into” means is to divide, always. What division does is show how much a number can fit inside another one. For example, 4 divided by two. If four is split into two equal parts, you get two. So four divided by two is two.

The exact same thing is happening in this situation; except with bigger numbers that don’t go into each other evenly.

So, the answer is approximately two or exactly 2.59..

The number 27 goes into 70 a total of 2 whole times when only considering whole numbers. The result of dividing 70 by 27 gives approximately 2.59 if we take decimals into account.

The question is asking how many times does 27 go into 70. In other words, this is a division problem where 70 is the dividend (the number being divided) and 27 is the divisor (the number we are dividing by).

To find the answer, we simply divide 70 by 27. Using a calculator, we find that 70 divided by 27 equals approximately 2.59.

However, if we're only counting whole times, we only count the number before the decimal point. Therefore, 27 goes into 70 a total of 2 whole times.

Answer:

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

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 0) and (x₂, y₂ ) = (0, - 1) ← coordinates of intercepts

m = [tex]\frac{-1-0}{0=2}[/tex] = [tex]\frac{-1}{-2}[/tex] = [tex]\frac{1}{2}[/tex]

Answer: The mean increases by 2.1

Step-by-step explanation:

According to the given description (dots are denoting the frequency for each value), the given data is :-

50 , 72, 72 , 74, 76 , 78 , 79 , 79 , 79 80, 81, 82, 82, 82

[Note - We take 79 as the value between 78 and 80, 81 as between 80 and 82 ]

Mean = [tex]\overline{x}_1=\dfrac{\text{Sum of observations}}{\text{No. of observations}}[/tex]                   (1)

[tex]=\dfrac{1066}{14}=76.1428571429\approx76.1[/tex]

First Quartile: [tex]Q_1=[/tex] Median of the lower half ( 50 , 72, 72 , 74, 76 , 78 , 79 )

= 74

Third Quartile: [tex]Q_3=[/tex] Median of the upper half (  79 , 79 80, 81, 82, 82, 82 )

= 81

Interquartile range (IQR)=[tex]Q_3-Q_1=81-74=7[/tex]

According to the IQR rule,

Upper limit = [tex]1.5\times IQR+Q_3=1.5\times7+81=91.5[/tex]

Lower limit = [tex]Q_1-1.5\times IQR=74-1.5\times7=63.5[/tex]

Since 50 < 63.2 , so 50 is outlier .

When 50 is removed from the data , the new data will be 72, 72 , 74, 76 , 78 , 79 , 79 , 79 80, 81, 82, 82, 82

Mean = [tex]\overline{x}_2=\dfrac{\text{Sum of observations}}{\text{No. of observations}}[/tex]

[tex]=\dfrac{1016}{13}=78.1538461538\approx78.2[/tex]      (2)

Change in mean from (1) and (2)
