Consider the figure. What is the value of x?

Mathematics
1 answer:
QveST [7]3 years ago
6 0
7x+12
8x+3

Because it is a horizontal line the two angles must add up to 180°

So add the two angles up together and set it equal to 180°
7x+12+8x+3=180
Add the two x’s 7x+8x=15x
Add the constants 12+3=15

You get 15x+15=180
Now subtract 15 from both sides
15x=165
Now divide by 15 to get x
X=11

Problem asked——Find a quick and easy method to compute the sum of the first 100 counting numbers. No calculators allowed.
Darya [45]

Answer

Step-by-step explanation:

split the numbers into two groups (1 to 50 and 51 to 100), he could add them together vertically to get a sum of 101.

1     + 2   + 3   + 4   + 5   + … + 48 + 49 + 50

100 + 99 + 98 + 97 + 96 + … + 53 + 52 + 51

1 + 100 = 101

2 + 99 = 101

3 + 98 = 101

.

.

.

48 + 53 = 101

49 + 52 = 101

50 + 51 = 101

Final total would be 50(101) = 5050.

50 addition problems all adding up to 101 thats how i got 50x101

It took Margie 2 1/4hours to write a 1 1/2 page research paper . What was her hourly writing rate
WARRIOR [948]


Margie would take 1 hour and 30 minutes to write 1 page of her research paper. Think of it like a proportion:

2.25/ 1.5 = x/1

2.25 is the 2 1/4 converted which is the amount of hours she took.

1.5 is the 1 1/2 converted which are the amount of pages she wrote total.

1 on the right side of the proportion represents  1 page.

And x are the amount of hours used  to write 1 page.

And in solving that proportion  it would result in 1.5 or 1hr. and 30 min.
