6. Seeta thinks a number and subtracts 7/3 from it. She multiplies the result by 6. The result now obtained is 2 less than twice the same number she thought of. What is the number?​

Answer:

x = 3

Step-by-step explanation:

Use the distributive property to multiply 4 by 5x+3. Subtract 14x from both sides. Combine 20x and −14x to get 6x. Subtract 12 from both sides. Subtract 12 from 30 to get 18. Divide both sides by 6. Divide 18 by 6 to get 3.

Answer:

20x+12=14x+30

6x=18

x=3

Step-by-step explanation:

First, apply the distributive property:

4(5x+3) = 4 · 5x + 4 · 3 = 20x+12

Now, we have this equation

20x+12=14x+30

We need to group the elements now.

So, to bring all the elements with an "x," we subtract 14x from both sides.

20x-14x+12=14x+30-14x

We have this now

6x+12=30

Now, let's subtract 12 on both sides

6x+12-12=30-12

6x=18

Divide both sides by 6

x=3

1.5 or 1 ½ pages per min

Step-by-step explanation:

7.5/5=1.5

She reads 1 ½ pages per min

Answer: 1.5 pages per minute

Step-by-step explanation:

Divide the total number of pages she read by 5, the amount of time it took her. So it should look like this: 7.5/5

The answer is 1.5 pages per minute.

The probability of getting a number 6 as the first card and a queen as the second card is 4/663.

Probability is mathematically defined as the ratio of the number of outcomes of a particular event or occurrence to the total number of outcomes.

For a standard deck, there are 52 total outcomes since there are 52 cards. A standard deck is divided into four suits - hearts, clubs, spades, and diamonds - with 13 cards each. Each suit has nine numbered cards from 2 to 10, three face cards (king, queen, and jack), and an ace.

The probability of having a numbered 6 card is 4/52. The probability is the same for getting a queen. Although, the probability of getting 6 as the first card and the queen as the second is different. This kind of probability requires the multiplication rule.

First card probability = 4/52

Second card probability = 4/51

The total number of outcomes for the second card is reduced since the first card is not replaced.

Probability (6 then queen) = (4/52)(4/51)

Probability (6 then queen) = 4/663

Answer 1120.5

Step-by-step explanation:

The hours travelled on the highway is 1.3 hours.

The first step is to determine the distance Sam travelled on the city road. The formula that would be used is the average speed formula. The average speed is the ratio of total distance travelled and the total time travelled.

Average speed = distance /time

average speed x time = distance

Distance = 35 x 1.5 = 52.50 miles

The second step is to determine the distance travelled on the highway.

Distance travelled on the high way = 140 - 52.50 = 87.50 miles

Now, determine the total hours travelled:

Hours travelled = distance / average speed

87.50 / 65 = 1.3 hours

The probability that a randomly chosen fitness club member signs up for a free running session is 0.4.

Let total s members sign up for the weightlifting session.

So, the total members for the running session is 2x.

And the total members for the swimming session be 2x.

Also here it is given that, thirty of the fitness center members sign up for a free session.

⇒ x + 2x + 2x = 30

⇒ 5x = 30

⇒ x = 30/5

⇒ x = 6

Thereofre, the probability that a randomly chosen fitness club member signs up for a free running session

= total number of members in running session/ number of members sign up for a free session

= 12/30

= 0.4

Hence, the probability that a randomly chosen fitness club member signs up for a free running session is 0.4.

By unitary method, we get that the total cost of mixture per pound = 50 cents.

A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method.

Given:

Cost of 1 pound sunflower seeds = 32 cents.

Cost of 1 pound cracked corn = 18 cents.

Available sunflower seeds = 10lb = 10 pounds

Available cracked corn = 16lb = 16 pounds

To find: Cost of the mixture per pound

You want the fraction of integers in the range [1, 100] that are divisible by 2, 3, or 5.

Attached is a Venn diagram showing how the divisibility of numbers from 1 to 100 stacks up. Circle A includes all 50 numbers divisible by 2; Circle B counts all 33 numbers divisible by 3; and Circle C counts the 20 numbers divisible by 5.

Where the circles overlap, there are counts of the numbers divisible by the relevant combination of factors. For example, there are 3 numbers divisible by 2, 3, and 5. (They are 30, 60, 90.)

In all, there are 74 numbers in the range 1–100 that are divisible by 2, 3, or 5.

The probability that a card chosen at random will have a number divisible by 2, 3, or 5 is 74/100 = 37/50.

  P( 2, 3, or 5 divides N) = 37/50.

If the main courses at a restaurant all contain rice or onion and of the 23 choices, 17 contain onion and 14 contain rice, then the number of dishes containing both rice and onion will be equal to 8.

The number of dishes that contain both rice and onion at the restaurant can be calculated by using an algebraic expression.

An algebraic expression can be defined as an equation in which both numerals and letters are present.

An algebraic expression for this problem can be given as,

(14 - x) + x + (17 - x) = 23

Here x is equal to the number of dishes containing both rice and onion.

14 + 17 - x + x - x = 23

The general equation for the sum of the first n terms Sₙ of a geometric sequence with common ratio r and first term a₁ is

[tex]S_n = a_1 \dfrac{1-r^n}{1-r}[/tex]    

Problem 59

Here we are given
[tex]S_n = \dfrac{31}{4}\\\\r = \dfrac{1}{2}[/tex]

So we can plug these values into the above equation and get [tex]a_1[/tex]

Let's first compute [tex]1 - r^n[/tex]
[tex]1 - r^n = 1 - \left(\dfrac{1}{2}\right)^5\\\\\left(\dfrac{1}{2}\right)^5 = \dfrac{1}{32}\\\\1 - r^n = 1 - \left(\dfrac{1}{2}\right)^5 = 1-\dfrac{1}{32} = \dfrac{32}{32}-\dfrac{1}{32} = \dfrac{31}{32}[/tex]

[tex]1- r = 1 - \dfrac{1}{2} = \dfrac{1}{2}[/tex]

So
[tex]\dfrac{1-r^n}{1-r} = \dfrac{31}{32} \div \dfrac{1}{2} = \dfrac{31}{32} \times \dfrac{2}{1} = \dfrac{31}{16}[/tex]

Substituting this value into [tex]S_n = a_1 \dfrac{1-r^n}{1-r}[/tex]  we get

[tex]\dfrac{31}{4} = a_1\dfrac{31}{16}[/tex]

Multiplying both sides by [tex]\dfrac{16}{31}[/tex]
[tex]\dfrac{31}{4} \times\dfrac{16}{31} = a_1\dfrac{31}{16} \times\dfrac{16}{31}\\\\4 = a_1 \textrm{or alternatively }\\ \\\boxed{a_1 = 4}[/tex]

Given perimeter = 26 , then

2a - 3 + 2a + 3a + 1 = 26 , that is

7a - 2 = 26 ( add 2 to both sides )

7a = 28 ( divide both sides by 7 )

a = 4

then

shortest side = 2a - 3 = 2(4) - 3 = 8 - 3 = 5

Step-by-step explanation:

If we have a line y = mx + b where m is the slope and be is the y-intercept then a line perpendicular to this line will have slope -(1/m)

So the slope of the line perpendicular to y = -3x + 5 will be [tex]-\dfrac{1}{3}[/tex] = + 1/3 = 1/3

So the perpendicular line equation is

y = (1/3)x + b where b is the y intercept of this line

Since it passes through the point x = 4, y = -1 we plug in these values for x and y and solve for b

We get
