Mr Nickelson tells the class that they double the least common denominator for 1/2 3/5 and 9/15 to find the number of the day wh

Nataliya [291]

Given fractions are $\frac{1}{2} ,\frac{3}{5} ,\frac{9}{15}$

To find the least common denominators of the given fractions, we need to find the least common multiple (L.C.M.) of the numbers given in denominators i.e. 2, 5, and 15.

Finding the LCM of 2, 5, and 15 :-

2 = 1 x 2

5 = 1 x 5

15 = 3 x 5

So least common multiple of 2, 5, and 15 would be (1 x 2 x 3 x 5) = 30.

Hence, common denominator would be 30.

The teacher tells us to double the common denominator to find the answer that is the number of the day.

So we need to double the value of common denominator i.e. 2 x 30 = 60.

It means that 60 is the number of the day.

Hence, 60 is the final answer.

What is the value of x

AnnZ [28]

Answer:

x = 8

Step-by-step explanation:

Formula for sum of interior angles is 180(n - 2)

For a 5 sided polygon the sum is;

180(5 - 2) =540°

The supplement of ∡ 59° = 180° - 59° = 121°

The supplement of ∡ 77° = 180° - 77° = 103°

The supplement of ∡ 66° = 180° - 66° = 114°

The supplement of ∡ 62° = 180° - 62° = 118°

The sum of the polygon is:

121° + 103° + 114° + 118° + (180 - 12x)° = 540°

456° + (180 - 2x)° = 540°

(180 -12x)° = 540° - 456° = 84°

12x = 180° - 84° = 96°

x = 96/12 = 8

How do you graph linear equation x+y=4

Sliva [168]

Answer:

See attached picture.

Step-by-step explanation:

To graph the linear equation, convert x+y=4 into y= -x+4. This means that y= mx+b is y=-x+4. So m = -1 and b =4.

Start with b by finding 4 on the y-axis. Plot a point. Then from this point move down 1 unit and 1 unit to the right to (1,3). Plot this point. Connect the points.
