Are there any numbers that go into 78 and 780?

78 ÷ 2 = 39
780 ÷ 2 = 390

2 can be a number that goes in 78 and 780.

As well as 2, 3 and 6 go into 78 and 780 too. That's all the single numbers that can divide it without getting decimals.

dedylja [7]
The answer is 2.

3/2a - ab + 1
3/2(5/6) - 5/6(3/10) + 1
5/4 - 1/4 + 1
4/4 + 1
1 + 1 = 2

Which triangle results from a reflection across the line x = 1?
Nataly_w [17]

Answer:

Correct answer is option D.

Step-by-step explanation:

Given that \triangle ABC in the image 1 attached.

If we have a look at the image attached, the coordinates are:

A(1,1)\\B(2,5)\ and\\C(4,1)

<em>To find reflection</em> of a point across any line, the distance of points from the line must be same.

Point A(1,1) lies on the line x = 1, so its reflection A' will be at the same point A'(1,1).

Point C(2,5) is at a distance 1 from x = 1 on right side, so C' will be 1 distance on the left side of x = 1 i.e. 1 will be subtracted from its x coordinate.

i.e. C'(1 - 1, 5)

C'(0, 5)

Point B(4, 1) is at a distance 3 from x = 1 on right side, so B' will be 3 distance on the left side of x = 1 i.e. 3 will be subtracted from its x coordinate.

i.e. B'(1 - 3, 1)

B'(-2, 1)

<em>When we plot the above point A', B' and C', we get the option D as correct.</em>

Find 3 consecutive odd integers whos sum is 28
DerKrebs [107]
I'm going to assume you meant 27 because three odd integers added together can't be even.

The three integers are expressed as x, y and z:

x+y+z=27
x+2=y
y+2=z
x+4=z

x+x+2+x+4=27
x+x+x+2+4=27
3x+6=27
3x=21
x=7
y=9
z=11

7+9+11=27

The numbers are 7, 9 and 11

Hope this helps.
