**Answer 1**

Answer:

144 pages.

Step-by-step explanation:

Given: Pages read on Monday= 25

Pages read on Tuesday is 1/2 of total pages.

Pages read on Wednesday is 52 pages.

Total number of pages is "x".

Now, finding the value of "x".

First lets find the pages read on tuesday.

Pages read on tuesday= .

Next, we know total pages in the book is equal to pages read on different days of week.

∴

⇒ x=

subtracting on both side.

⇒

⇒

Cross multiplying on both side.

∴x=

Hence, total pages in the book are 144.

Answer:

An equation is a statement (a sentence) that says that two expressions (phrases) are equal ( are the same ) —even if they look different. The expression 4 and the expression 1+3 look different, but they represent the same thing. An expression is a meaningful collection of constants, variables, and/or operations.

Answer:

7

Step-by-step explanation:

We do not know the number, so we will let a variable take its place. I will be using n to represent this unknown number.

n=mystery number

Now that we have a variable, we can perform operations on it. Five less than four times a number is multiplying the number by 4 and then subtracting it by 5.

4n-5

Assuming that the second part is equal to the first part, nine more than twice a number is multiplying the number by 2 and then adding 9. We can set this equal to our previous expression.

4n-5=2n+9

2n-5=9

2n=14

n=7

Solving this equation is all we have to do to find the answer.

6+a thats the question

### Answers

Answer:

a + 6

the variable (the letter if thats what you call it) should always go first cause you would never know if that letter is greater than or less than or equal to 6.

Also, since we don't know the number "a", we can't add it to 6.

so, therefore, your answer is "a + 6"

Find the slope of y=7.5x

### Answers

Hey there!

This equation is a linear equation since its variable is only raised to the first power (x^1). Knowing that it is linear, you know that linear equations are always in the form of y = mx + b where m is the slope and b is the y-intercept.

In this case, the b=0 and your m=7.5.

Therefore, the slope is 7.5

An event planner expects 432 teachers to attend a conference. If the planner places 24 chairs in each row, estimate the number of rows needed to provide seating for all of the teachers.

### Answers

18 rows are needed to provide seating for all of the teachers.

Step-by-step explanation:

Given,

Number of teachers expected = 432

Number of chairs in one row = 24

We will divide the number of teachers expected by number of chairs in each row to find the number of rows.

Number of rows =

Number of rows = 18 rows

18 rows are needed to provide seating for all of the teachers.

Is 3(x+2)=3x+5 true?

### Answers

Hey there!

The equation is not true.

To figure out whether or not the equation is true, first simplify the left side by distribution:

3(x+2)= 3x+6

Now, you have 3x+6=3x+5, which, at first glance is obviously not equal.

However, in order to be sure, simplify the equation further by subtracting like terms from both sides:

3x+6=3x+5

3x-3x+6=5

6=5

6 does not equal 5, therefore, you have have proven that 3(x+2)=3x+5 is not true.

A car wheel is 56 cm in diameter. A. How far does the car go in one revolution of the wheel? B. How far does it go in 100 revolutions?

### Answers

The car moved 175.84 cm in one revolution

The car has moved 17584 cm in 100 revolutions

Solution:

Given that car wheel is 56 cm in diameter

diameter = 56 cm

To find: distance traveled in one revolution of wheel

Usually wheel is of circular shape

one revolution of wheel = circumference of circle

The circumference of circle is given as:

We know that,

diameter = 2(radius)

So the circumference becomes:

substitute = 3.14 and d = 56 cm

Thus the car moved 175.84 cm in one revolution

B. How far does it go in 100 revolutions

Distance covered in 100 revolutions = 100 x Distance covered in 1 revolution

Thus the car has moved 17584 cm in 100 revolutions

Birds bakery has been open 3 times longer than Bridget's bakery and Bridget's bakery has been open for 6 years so how long has Birds bakery been open?

### Answers

Answer:

18 years

Step-by-step explanation:

Given:

Birds bakery has been open 3 times longer than Bridget's bakery.

And Bridget's bakery has been open for 6 years.

So, the Birds bakery open time = 3 Bridget's bakery open time

Birds bakery open time = 3 6

Birds bakery open time = 18 years

Therefore, the Birds bakery has been open for 18 years.

How much digital money do you have now if you originally had $341.22, and you made deposits of $33.77 and $21.68 and withdrawals of $35.62 and $59.01?

### Answers

Answer:

$302.04

Step-by-step explanation:

We find the total of the deposits by adding $33.77 and $21.68.

33.77+21.68=55.45

We find the total of the withdrawals by adding $35.62 and $59.01.

35.62+59.01=94.63

The total of the withdrawals is greater than the deposits so we know that the amount of digital money will decrease. We set up a simple problem to solve for the amount remaining.

341.22-(94.63-55.45)=302.04

We got this answer because we subtracted the total of the deposits from the total of the withdrawals and then subtracted the answer from the amount of digital money.

Eduardo bought one dozen bunches of seedlees black grapes for $8. How many

bunches of seedless black grapes can he

buy for $20

### Answers

30 bunches of seedless grapes can be bought for the rate of 20$

Step-by-step explanation:

Step 1:

one dozen seedless grapes is bought for $8 so that is given by,

one dozen = 12

Step 2 :

$8 for one dozen is = 12/8 = 1 and a half dollars or 1.5$ is the cost of a bunch

Step 3:

for 20$, the bunches of seedless grapes that can be bought is given by,

= 20×1.5

= 30

hence with this conclusion we know that 30 bunches of grapes can be bought with $20

Are 7 baskets of 100 beads the same as 6 baskets of 100 beads and 1 basket of 10 beads

### Answers

Answer:

No

Step-by-step explanation:

7 baskets of 100 beads:

There are 100 beads in 1 basket, so there are

beads in 7 baskets.

6 baskets of 100 beads and 1 basket of 10 beads:

There are 100 beads in 1 basket, so there are

beads in 6 baskets.

The total amount of beads in 6 baskets of 100 beads and 1 basket of 10 beads is

beads.

Hence, the amounts are not the same

Ogechi said the formula is h(n)=8\cdot1^{\large{n}}h(n)=8⋅1

n

h, left parenthesis, n, right parenthesis, equals, 8, dot, 1, start superscript, n, end superscript.

Which one of them is right?

### Answers

Answer:

will be the correct formula for the given sequence.

Step-by-step explanation:

The given sequence is 1, 8, 64, 512...........

The given sequence is a geometric sequence having a common ratio (r) of

r =

r =

Since explicit formula of a geometric sequence is given by

where = nth term of the sequence

a = first term of the sequence

r = common ratio of the successive term to the previous term

Now we plug values of a and r in the formula to get the explicit formula for the given sequence.

Therefore, if Bernardo is saying that the formula of the sequence is

h(n) = then he is correct.

An event planner expects 432 teachers to attend a conference. If the planner places 24 chairs in each row, estimate the number of rows needed to provide seating for all of the teachers.

### Answers

Answer:

The number of rows needed to provide seating for all teachers is 18.

Step-by-step explanation:

Here, the total number of guests expected to attend = 432 teachers

Now, given : The number of chairs placed in each row = 24

Let us assume , the total number of rows of chairs = m

Now, The total chairs in the conference room

= The number of rows x The chairs in each row

= 24 x (m) = 24 m

Also, the TOTAL CHAIRS = TOTAL GUEST EXPECTED

⇒ 24 m = 432

or, m = 432 / 24 = 18

or, m = 18

Hence, the number of rows needed to provide seating for all of the teachers is 18.
