Consecutive integers are 1 more than the other.
If one of them is x.
The three would be x, x + 1, x + 2
Since the sum are 138
x + (x + 1) + (x +2) = 138
x + x + 1 + x +2 = 138
x + x + x + 1 + 2 = 138
3x + 3 = 138
3x = 138 - 3
3x = 135
x = 135/3
x = 47.
So the numbers are, x, x + 1, x + 2, = 47, 47 + 1 = 48, 47 + 2 = 49
The integers are 47, 48, and 49.
Answer:
4583 Million is
4583 x 106
or
4,583,000,000
STEP 1:
Triangles= 180°
Other Angles= 7:13= 7x + 13x
Add all the angles to equal 180°
140° + 7x + 13x= 180°
combine like terms
140° + 20x= 180°
subtract 140 from both sides
20x= 40
divide both sides by 20
x= 2
STEP 2:
substitute x value to find other two angles
7x= 7(2)= 14° one angle
13x= 13(2)= 26° other angle
CHECK:
140° + 14° + 26°= 180°
140 + 40= 180
180= 180
ANSWER: The other two angles measure 14° and 26°.
Hope this helps! :)
