x + x + 1 + 2 = 48? ​

Answers

Answer 1

Step-by-step explanation:

x + x + 3 = 48

2x = 48 - 3

2x = 45

x = 45/2

Answer 2

Answer:

x = 45/2

Step-by-step explanation:

x+x+1+2 = 48

combine like terms

2x + 3 = 48

2x - 3 = -3

     2x = 45

  2x/2 = 45/2

       x = 45/2

3: Mary has 26 sweets and is able to share them evenly between her friends.
Mary has more than 1 friend.
Write down how many friends Mary might have.​

Answers

Answer:

Mary has 12 friends, and a total of 13 people including her. Or, she has 25 friends, and a total of 26 people including her.

Step-by-step explanation:

First, we know that 26 is divisible by 1, 2, 13, and 26 because (2x13) and (1x26) both equal 26 but we know that Mary has more than 1 friend and if Mary is also added to the group where the candy is divided, that means that 1 and 2 are both out because Mary has more than 1 friend so 1 cannot be the answer and if Mary has 2 friends, that means that the candy would have to be divided 3 ways which is not possible evenly so the answer is either 12 friends or 25 friends.

what is 5/6 + 4/6 + 1/6?

Answers

the correct answer is 1 5/6

Answer:

The answer would be 1 2/3.

Step-by-step explanation:

The equation y=3.2x represents the cost y (in dollars) for a taxi ride during peak hours that costs x dollars during off-peak hours. a. Solve the equation for x.

Answers

Answer:

x = y / 3.2

Step-by-step explanation:

Given:

y = 3.2x

Where

y = cost for a taxi ride during peak hours (in dollars)

x = cost for a taxi ride during off-peak hours (in dollars)

Solve the equation for x.

y = 3.2x

Divide both sides by 3.2

y / 3.2 = 3.2x / 3.2

y / 3.2 = x

x = y / 3.2

This means,

Cost for a taxi ride during off-peak hours (in dollars) = Cost for a taxi ride during peak hours (in dollars) / 3.2

Answer:

Fourth option

Step-by-step explanation:

We know that A and B are rational numbers because they can be written as the quotient of two integers. Therefore, that eliminates the first and third options because they state that (at least) one of the numbers is irrational but we know that both are rational, hence, they are incorrect. The second option is incorrect because A · B = [tex]\frac{mn}{pq}[/tex], not [tex]\frac{mp + nq}{pq}[/tex], therefore, the correct answer is the fourth option.

What is the sum of the measures of the interior angles of an octagon? Enter your answer in the box.

Answers

So, 360/8 = 45 degrees each time. The internal angle is 180-45=135. And 8*135=1080. The sum of the interior angles of a polygon is (n - 1)180, where n is the number of sides.

The sum of interior angles of an octagon will be 1080°.

We have a Octagon.

We have to find the sum of the measures of the interior angles of a pentagon.

What is Octagon ?

In geometry, a Octagon is a eight - sided polygon.

According to the question, we have - A Octagon.

The formula for finding sum of the measures of the interior angles of a polygon is = ( n - 2) x 180°. The number of triangles in each polygon is two less than the number of sides.

The formula for calculating the sum of interior angles is:

For a Octagon - n = 8.

Therefore - the sum of interior angles of an octagon will be -

(8 - 2) x 180

180 x 6

1080°

Hence, the sum of interior angles of an octagon will be 1080°.

how do you round up/down numbers PLEASE ANSWER​

Answers

Answer:If the number is over 5 then you go to the next number

Step-by-step explananation

7.99 = 8 its over 5

For an example I’ll use 999.56

It depends on what place you are rounding to but if a number is 5 or larger, you round up. And if it is 4 or smaller, round down. If you wanted to round the example to the tenths place you would look at the number to the right of it and see if it is bug enough to round. So if you were rounding the example to the tenths place it would be 999.6
