Answer:

1. Make imporper franctions: 2 1/2 = 5/2    1 2/5 = 7/5

2. Find common denominater: using 10

5/2 =  25/10       7/5 = 14/10

3. Simplify.

25/10 -  14/10 = 11/10

=  1 1/10

Solve for x: 3|x − 3| + 2 = 14
vaieri [72.5K]

Answer:

x = 7                      x = -1

Step-by-step explanation:

3|x − 3| + 2 = 14

Subtract 2 from each side

3|x − 3| + 2 -2= 14-2

3|x − 3|  = 12

Divide by 3

3|x − 3| /3 = 12/3

|x − 3| = 4

Now the absolute value has a positive and negative solution.

x-3 = 4      x-3 = -4

Add 3 to each side

x-3+3 = 4+3      x-3+3 = -4+3

x = 7                      x = -1

A navel distress signal flag is in the shape of a triangle. Two of the three angles measure 55 degrees each. What is the measure
Alekssandra [29.7K]

The measure of third angle is 70 degree

<h3><u>Solution:</u></h3>

Given that, a navel distress signal flag is in the shape of a triangle

Two of the three angles measure 55 degrees each

We know that there are three angles in triangle

The angle sum property of a triangle states that the angles of a triangle always add up to 180°

Every triangle has three angles and whether it is an acute, obtuse, or right triangle, the angles sum to 180°

Let three angles be "A", "B", "C"

Given that two angles measure 55 degrees each. Let say angle A = angle B = 55

<em><u>By angle sum property of triangle,</u></em>

Angle A + angle B + angle C = 180 degree

55 + 55 + angle C = 180

110 + angle C = 180

angle C = 180 - 110 = 70 degree

Thus the measure of third angle is 70 degree
