Choose all the numbers that could be common denominators for 2/3 and 3/4. 8, 12, 16, 36, 48

Answer: t1 = -34; t2 = -64; t3 = -94

d is the distance between numbers (d > 0)

we have:

t5 = t1 + 4d = -154

t9 = t1 + 8d = -274

we have the equations:

t1 + 4d = -154

t1 + 8d = -274

<=> t1 = -34

      d = -30

with t1 = -34 and = -30 => t2 = -34 - 30 = -64

                                          t3 = -64 - 30 = -94

Day 1=15 Day 2=30 Day 3=45 Day 4= 60 Day 5= 75. The expression is N+15

Step-by-step explanation:

The complete table:

Days                  1    2     3    4     5

Total samples  15  30  45  60   75

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of bacteria samples analyze each day = 15

The equation for the number of bacteria analyzes after x days.

B = 15x

Now,

x = 1, B = 15

x = 2, B = 30

x = 3, B = 45

x = 4, B = 60

x = 5, B = 75

Thus,

Days                  1    2     3    4     5

Total samples  15  30  45  60   75

Answer:

8.5

Step-by-step explanation:

Twice the difference of a number and 6 equals 5 is written algebraically as 2(x-6)=5, where x is the number. Solving for x:

2(x-6)=5

(x-6)=5/2

x=6+5/2

x=17/2

So the number is 17/2, or, expressed as a decimal number, 8.5

Answer:

(i)The length of room = 5.5 m and width of the room = 4 m

The length of room with verandah = 5.5 + 2.25 + 2.25 = 10 m

The width of room with verandah = 4 + 2.25 + 2.25 = 8.5 m

Area of verandah = Area of room with verandah – Area of room without verandah = Area of ABCD – Area of EFGH = (AB x AD) – (EF x EH) = (10 x 8.5) – (5.5 x 4) = 85 – 22 = 63 m2

(ii) The cost of cementing 1 m2 the floor of verandah = Rs 200 The cost of cementing 63 m2 the floor of verandah = 200 x 63 = Rs 12,600

Answer:

b = 12

Step-by-step explanation:

First, distribute 3/4 to both terms in the parentheses:

3 = 3/4(b - 8)

3 = 3/4b - 6

Now, solve for b:

9 = 3/4b

12 = b

So, the answer is b = 12

Answer:

12

Step-by-step explanation:

3 = 3/4 x (b-8)

Distribute 3/4 through the parentheses

3 = 3/4 b - 6

Multiply both sides of the equation by 4

12 = 3b - 24

Move the variable to the left - hand side and change its sign

-3b = -24 - 12

Calculate the difference

-3b = -36

Divide both sides of the equation by -3

B = 12

Answer:

3 days

Step-by-step explanation:

First, let's convert 400 meters to km (kilometers):

To find km from m we divide the meters by 1000:

400/1000 = 0.4

Therefore, there are 0.4 km in 1 meter.

Kali runs 10 laps every day, since 1 lap is 0.4 km we can multiply 10 by 0.4 to see how many kilometers they run in 1 day:

(10)(0.4) = 4

Kali runs 4 kilometers every day

Now, we can find how long it will take Kali to run a total of 12 kilometers by dividing 12 by 4

12/4 = 3

It will take Kali 3 days to run a total of 12 kilometers.

Step-by-step explanation:

Given

f(x) = 5 / 2x - 1

f^-1( x) = ?

Let

y = f(x)

y = 5/2x - 1

Interchanging the roles of x and y we get

x = 5/2y - 1

2y - 1 = 5/x

2y = 5/x - 1

y = (5/x - 1)/ 2

f^-1(x) = ( 5/x - 1) / 2

Step-by-step explanation:

LET THE THREE CONSECUTIVE EVEN INTEGERS BE

(x+2) ,(x+4) ,(x+6)

then

according to the question

4(x+2) – (x+6) = 2(x+4) + 6

4x + 8 – x – 6= 2x + 8+6

3x +2 = 2x + 14

3x – 2x= 14 –2

x= 12

the numbers are

14

16

18

Answer:

The three numbers are 14, 16, 18.

Step-by-step explanation:

Consecutive even integers differ by 2.

You can let the smallest of the three numbers equal x. Then the other two numbers are x + 2 and x + 4.

Now use x, x + 2,and x + 4 to represent the 3 numbers and follow the directions to write an equation. The equation will have only one variable, x, so you can solve for x.

"four times the first" ----->   4x

"minus the third"   ------->    -(x + 4)

"is"  ----->     =

"six more than twice the second"   ------>    2(x + 2) + 6

Put all the pieces in boldface together to arrive at your equation.

4x - (x + 4) = 2(x + 2) + 6

Simplify the parentheses on both sides by distributing.

4x - x - 4 = 2x + 4 + 6

Combine like terms on both sides.

3x - 4 = 2x + 10

Subtract 2x from both sides.

x - 4 = 10

Add 4 to both sides.

x = 14

The smallest number is 14.

x + 2 = 14 + 2 = 16

x + 4 = 14 + 4 = 18

Answer: The three numbers are 14, 16, 18.
