3(x-3) = -2x + 31 what is the value of x?

Answers

Answer 1

Answer:

x= 8

Step-by-step explanation:

1. Expand.

3x-9=-2x+31

2. Add 9 to both sides.

3x=-2x+31+9

3. Simplify  -2x+31+9  to -2x+40.

3x=-2x+40

4. Add 2x to both sides.

3x+2x=40

5. Simplify  3x+2x+5x.

5x=40

6. Divide both sides by 5.

x = 40/5

7. Simplify 40/5 to 8.

x=8

What is 9/2 × 20/3 × 9/4?

Answers

Answer:

67.5

Step-by-step explanation:

4.5 times 6.66 times 2.25 will be 67.5

Well, when multiplying fractions together, you don’t really have any problem of converting fractions for common denominators or any of that stuff and instead it’s actually quite simple because you just have to straight multiply the numerators and the denominators

9/2 * 20/3 * 9/4
= (9 * 20 * 9)/(2 * 3 * 4)
= (1620)/(24)
= 1620/24
= 67.5

So, in conclusion, 9/2 * 20/3 * 9/4 is equal to 67.50 or 1620/24.

A plant is already 54 centimeters tall, and it will grow one centimeter every month. The plant's height, H (in centimeters), after M months is given by the following.
What is the plant's height after 13 months?

Answers

Answer:

67 cm

Step-by-step explanation:

We are given the initial height of the plant let's call it H.

H = 54 cm. This is the original height of the plant at M(months) = 0.

We are given that it grows at 1 cm/month. This is the rate of growth.

Rate = 1

Time (M) is given in Months.

So when M = 0, H = 54

Let's say M = 1, That is one month has passed. In this time the plant's height would have increased by 1 cm. So our plant's height would be H = 54+1 = 55 cm.

When Two months have passed our plant's height would be H = 54 + 2 = 56 cm , since every month our plant gains 1 cm in Height, we can make a fuction for this.

H = 1M + 54.

Now we just plug in 13 for M, to get 13 months.

H = 13 + 54

H = 67 cm

So our plant would be 67 cm in height after 13 months.

Lena drove 355 miles using 17 gallons of gas. At this rate, how many gallons of gas would she need to drive 284 miles.​

Step-by-step explanation:

Miles Driven = Gallons Burnt * Miles Per Gallon

 

So if yo drive 20.88 miles on one gallon how many gallons does it take to drive 284 miles.  This is 284/20.88 = 13.6 gallons

Chipotle Burritos are normal distributed with a mean length of 200mm and a standard deviation of 8mm. What is the probability that a burito picked at random is shorter than 190mm?

Answers

Answer: 0.1056

Step-by-step explanation:

Given: Chipotle Burritos are normal distributed with

Mean =  200 mm

Standard deviation = 8 mm

Let x be the length of a random burrito.

The probability that a burrito picked at random is shorter than 190mm will be :

[tex]P(x<190)=P(\dfrac{x-\mu}{\sigma}<\dfrac{190-200}{8})\\\\=P(z<-1.25)\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(z<1.25)\\\\=1-0.8944\\\\=0.1056[/tex]

Hence, the probability that a burrito picked at random is shorter than 190mm is 0.1056.

Calculate the area of the parallelogram, giving your answer correct to 3 significant figures.

Answers

Answer:

114 units²

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, so

AB = CD , that is

13x - 7 = 5x + 9 ( subtract 5x from both sides )

8x - 7 = 9 ( add 7 to both sides )

8x = 16 ( divide both sides by 8 )

x = 2

Then

5x + 9 = 5(2) + 9 = 10 + 9 = 19

3x = 3(2) = 6

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height ), thus

A = 19 × 6 = 114 units²

A sports drink bottle contains 16.9 fluid Ounces. Andre drank 80% of the
bottle. How many fluid Ounces did Andre drink?

Answers

Answer:

13.52 fluid ounces should be the right answer! :)

Step-by-step explanation:

Andre drank from the bottle 13.52 fluid ounces if he drank 80% of bottle.

What is Percentage?

Percentage is defined as the parts of a number in a whole of 100. This is denoted by the symbol '%'.

In other words, percentage can be defined as the ratio expressed as a fraction of 100.

Any number can be expressed as a percentage of another number by dividing the number with the whole of other number and then multiplying with 100.

Given that, fluid contained in a sports bottle = 16.9 fluid ounces.

Andre drank 80% of the fluid contained in the bottle.

80% of the bottle = 80% × 16.9

                             = (80 / 100) × 16.9

                             = 0.8 × 16.9

                             = 13.52

So this is the total fluid ounces Andre drink.

Hence Andre drank 13.52 fluid ounces from the bottle.

One political factor that caused World War II was the Treaty of Versailles. The Treaty of Versailles created political tension between countries, as some provisions that were outlined within the treaty were unfair towards some of the parties involved. Take Italy for example; thousands of Italians had died in the war, but Italy was not given the land and reparations they were promised. This led to a rise in nationalism, and more Italians feeling resentment towards the Triple Entente for their abundant debt and little assistance. This is also an economic factor that caused World War II, as the aftermath of World War II left Italy in ruins, both literally and financially, and made it so that they desperately needed hope. This, in turn, led to Benito Mussolini coming into power, boasting promises of a greater Italy in the near future. Similarly, the Treaty of Versailles left Germany in a lot of debt, and many German citizens were suffering. Hitler, a charismatic leader who took advantage of the political and economic turmoil, took over and gave Germany an excuse for their problems: the Jewish population. Another economic factor that caused World War II was the worldwide depression, which put a lot of countries in a very bad position. Also, the rise of fascism and totalitarianism definitely contributed to the way World War II started, as many of the agitators of the war were in the Axis powers, and were under totalitarian dictators.
