Answer:

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

Remark

The two angles across from each other are equal.

Equation

5x - 1 = 124                  Add 1 to both sides

Solution

5x - 1  + 1 = 124 + 1      Combine

5x = 125                      Divide by 5

5x/5 = 125/5

x = 25                

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:

6 curtains can be made

Step-by-step explanation:

so your dividing by a fraction so you want to convert all numbers into fractions

4/1 divided by 2/3

an easier way to divide fractions is to flip the right one over

2/3->3/2

then multiply

4/1 x 3/2 = 12/2 = 6

Answer:

6 curtains

Step-by-step explanation:

to figure out how many curtains she can make, we have to divide 4 by [tex]\frac{2}{3}[/tex].

[tex]\frac{4}{2/3}[/tex]

However, whenever you divide with fractions, you have to multiply by the reciprocal of the fraction.

[tex]\frac{4}{2/3}[/tex] ⇒ [tex]\frac{4}{1}[/tex] × [tex]\frac{3}{2} = \frac{12}{2} =6[/tex]

Answer:

A. A straight line can be drawn through all the points and the line passes through the point (0,0) .

Step-by-step explanation:

See comment for options

Given

A graph with proportional relationship

Required

Which of options (a to d) describes the graph

A graph with a proportional relationship is represented as:

[tex]y = kx[/tex] and

[tex](x,y) = (0,0)[/tex] is a paired point on the graph

This implies that options (b) and (c) are not true

Option (d) is also incorrect because if the graph does not pass through all points, then it is not proportional.

Hence, (a) is correct

Answer:

19/24 = 0.791666667

Step-by-step explanation:

7/8 - 1/12

Least common multiple of 8 and 12 is 24. Convert 7/8 and 1/12 to fractions with denominator 24.

21/24 - 2/24

Since 21/24 and 2/24 have the same denominator, subtract them by subtracting their numerators.

21 - 2 / 24

Subtract 2 from 21 to get 19.

Answer:

A and C

Step-by-step explanation:

The equivalent expressions are:

3(p + 5) and 7p - 4p + 15

Options A and C are the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

3p + 15

Taking out common factors.

3 (p + 5)  ____(1)

And,

7p - 4p + 15

3p + 15

3(p + 5) _____(2)

From (1) and (2),

3(p + 5) and 7p - 4p + 15 are equivalent expression.

Thus,

The equivalent expressions are:

3(p + 5) and 7p - 4p + 15

Answer:

simple just follow me and mark it brainliest

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.

Step-by-step explanation:

you have to find the LCM (least common multiplier) of 2,and 8 and that would be 8 therefore youd change the fractions from 1/2-1/8 to 4/8-1/8  you subtract the tops and keep the bottoms the same as 8. so 4-1=3 therefore the anwser would be 3/8

Hi there!

Convert 36 into 35 and 4/4 since if it is just a number, it can’t be multiply by 3/4.

[tex]36= 35 \frac{4}{4}[/tex]

Multiply both fractions now but also turn 35 4/4 into a mixed number:

[tex]36=\frac{144}{4}[/tex]

[tex]\frac{3}{4} x \frac{144}{4}= \frac{27}{1} = 27[/tex]
