Find three consecutive integers such that twice the sum of the first two is to less than three times the third
drek231 [11]

Answer:

Step-by-step explanation:

Let the consecutive integers be x - 1 , x , x + 1

Equation

2*(x - 1 + x) = 3*(x+1) - 2

Solution

2(2x - 1) = 3(x + 1) - 2           After the first two have been combined remove the brackets.

4x - 2 = 3x + 3 - 2               Combine the right

4x - 2 = 3x + 1

4x - 2 + 2 = 3x + 1 + 2         Add 2 to both sides

4x = 3x + 3                          Subtract 3x from both sides

4x-3x = 3x - 3x + 3             Combine

x = 3

Check

Left hand side

2(2 + 3)

2(5)

Right hand side

3*(x+1) - 2

Under which angle conditions could a triangle exist? Check all that apply.
ElenaW [278]
An acute angle is <90 degrees
a right angle is equal to 90 degrees
an obtuse angle is >90 degrees
Any triangle has angles adding to 180 degrees

therefore three acute angles, eg. 60, 60 and 60 degrees can make up a triangle

2 acute angles and a right angle, say 45 and 45 degrees and 90 degrees make a triangle

any obtuse angle + a right angle will be larger than 180 degrees, so no triangle can exist. another acute angle will make the number of degrees even larger

any 2 obtuse angles will make a number larger than 180 degrees, so with an acute angle is impossible

2 acute and an obtuse angle is possible, say 40, 40 and 100 degrees
