The sum of 3 consecutive odd numbers is 51 what is the second number in the sequence

Answers

Answer:

The second number in the sequence is 17.

Step-by-step explanation:

Let the three consecutive odd numbers be 2x-1,2x+1 and 2x+3

As per the question, the sum of the 2 odd numbers is 51.

So forming the relevant equation:

(2x-1) + (2x+1) + (2x+3) = 51

=> 6x + 3 = 51

=> 6x = 51-3 = 48

=> x = 48/6 = 8

Calculating the individual numbers:

2x-1 = 2*8 -1 = 16 - 1 = 152x+1 = 2*8+1 = 16 + 1 = 172x+3 = 2*8 +3 = 16 + 3 = 19

So the consecutive odd numbers are 15,17,19 and the second number in the sequence is 17.

A number has the digit 8 and 4 .to the nearest 10.the number round to 50.what is the number?

Answers

The number is 48. Round the 8 up to make it 50.

Given that digits 8 and 4 makes up a number, and when rounded, it gives us 50, the number would be: 48.

Recall:

When rounding a number, if the number close to the number you want to round is more than 4, you round up. For example, rounding 39 to nearest ten, 9 is more than 4. Therefore, we will round up 39 as 40.

If a number consist of 8 and 4, and we are to round the number so it gives us 50, the number would be: 48:

What is an expression?

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.

So, we can rewrite the expression as:

2¹/₃ ÷ 1/3 = (5/2) ÷ (1/3)

Now, we multiply the first fraction by the reciprocal of the second fraction:

(5/2) ÷ (1/3) = (5/2) × (3/1)

Multiplying the numerators and denominators, we get:

(5 × 3) ÷ (2 × 1) = 15/2

Therefore, 2¹/₂ divided by 1/3 is equal to 15/2, or 7¹/₂.

If h(x) = −2x − 10, find h(−4). −2 −18 −3 −16

Answers

If h(x) = -2x - 10 you should put the -4, -2. -18, -3 or/and -16 in the place of the x in the formula.
So for example:

h(-4) = -2 * (-4) - 10 = 8 - 10 = -2

Or at least, that's what I think the answer should be.

Good luck!

Answer:

The correct option is (a) i.e.

h(-4) = -2

Step-by-step explanation:

The mathematical expression is given as :

[tex]h(x)=-2x-10[/tex]......(1)

Where

h(x) is dependent on x

We need to find the value of h(x) at x = -4 . Putting the value of x in equation (1) we get :

[tex]h(-4)=-2(-4)-10[/tex]

[tex]h(-4)=8-10[/tex]

h(-4) = -2

The value of h(-4) is -2. So, the correct option is (a). Hence, this is the required solution.

Marvin is trying to finish 1/2 of his test every 2/3 hour. How many hours will it take Marvin to complete his whole test

Answers

If Marvin wants to complete 1/2 of his test in 2/3 of an hour. To get 1/2 to 1 you multiply it by 2. (1/2x2=1) You would then multiply 2/3 of an hour by 2 to get 4/3 of an hour to complete the whole test(2/3x2=4/3). 4/3 of an hour is equivalent to 1 hour and 20 minutes or 1 and 1/3 of an hour.

It will take Marvin 4/3 hours to complete his entire test.

Time taken to complete 1/2 of test = 2/3 hours

The total fraction of the test can be represented as 1

Therefore,

If 1/2 of test = 2/3 hours

1 of test = x

We can solve for x using cross multiplication :

1/2x = 2/3

Multiply both sides by 2 to isolate x

(1/2x × 2) = (2/3 × 2)

x = 4/3 hours

The number of hours it will take to complete the whole test is 4/3 hours

Two pounds of dried cranberries cost $5.04, 3 pounds of dried cranberries cost $7.56, and 7 pounds of dried cranberries cost $17.64. Write an equation that gives the cost y of x pounds of dried cranberries? Please explain how you got your answer!

Answers

The answer is y=2.52x

The cost equation for dried cranberries is y = 2.52x.

Cost equation:

Using the given data:

2 pounds for $5.04 means each pound costs $5.04/2 = $2.52.

3 pounds for $7.56 means each pound costs $7.56/3 = $2.52.

7 pounds for $17.64 means each pound costs $17.64/7 = $2.52.

Therefore, the cost equation: y = 2.52x where y is the cost and x is the pounds of dried cranberries.

A rate that describes how much smaller or larger the scale drawing is than the real object

Answers

i believe the answer is "scale factor." you usually find it by comparing the corresponding sides from two figures and creating a ratio of them; for example, imagine two squares. square A has sides that have the length of 8 inches. square B has sides that have a length of 4 inches. all sides are the same length with squares.

square A, length of left side = 8 in
square B, length of left side = 4 in

the ratio for this could be 8/4 (simplified to whole number 2) -- you would pick two corresponding sides (the left sides of each square) and think "when the left side on square A is 8 in, the left side on square B is 4 in. if i multiply 4 in by 2, i get the larger square, so square B is smaller by a factor of 2."

roger has twice as much money as carol. maria has 1/2 as much money as carol. Together they have $77. how much money does each have?

Answers

Roger would have 4 times as much as Maria
Carol would have 2 times what Maria has

We then add everything up, how big a cut, they each have

4+2+1 = 7

Now we divide the 77 by 7

77/7 = 11

Now we just multiply by how much each of them has

Maria = 11*1 = 11
Carol = 11*2 = 22
Roger = 11*4 = 44

C+(C*2)+(C/2)=77
C=22
Carol: $22.00
Roger: $44.00
Maria: $11.00
