My name is Ann [436]3 years ago
8 0

Step-by-step explanation:

In part (d), we are shown how the sum of consecutive integers can be found.  The sum is:

S = n (x + y) / 2

where n is the number of integers, x is the first integer, and y is the last integer.

We want to use this formula to find the sum of the numbers 101-110.  We know there are 10 numbers between 101 and 110, so n = 10.

S = 10 (101 + 110) / 2

S = 1055

We used deductive reasoning to find the answer.

Mrs. Jones bought three 2-kilogram packages of flour. How many grams of flour did she buy?
Makovka662 [10]

It is given that, Mrs. Jones bought three 2-kilogram packages of flour.

And

1 kilogram = 1000 grams

And three 2 -kilogram packages means she bought 6 kilogram flour .

So we need to convert 6 kilogram flour into grams.

If,

1 kilogram = 1000grams, \\ than, \\ 6 kilograms = 6*1000=6000 grams

So she bought 6000 grams of flour .

Find the value of x.
Deffense [45]

Answer:

Step-by-step explanation:

the funny lines in the corners of the triangle mean that the angles are the same.  Maybe you knew that?

The supplementary angle at the top right is just

180- 17x -23

now you have expressions for each of the 3 angles of the triangle which all add up to 180°

180= 7x + 2  +  7x +2   +  180- (17x -23)

180 = 14x +4 + 180 - 17x +23

180 = -3x +207

3x = 27

x = 9
