Answer:
x = 29, C

Explanation: We are given that total angle is 90°, or a right angle. This means that the two complementary angles must equal 90° together.

Create the equation:
2x - 4 + x + 7 = 90

Solve algebraically:
3x + 3 = 90
3x + 3 - 3 = 90 - 3
3x = 87
3x / 3 = 87 / 3
x = 29 or C

What would the graph of<br> Х/4.8 &lt; 1.25 look like?
Rina8888 [55]

Answer:

Step-by-step explanation:

x/4.8 < 1.25                             Multiply both sides by 4.8

4.8 x /  4.8 < 1.25*4/8

x < 6

What this means is that every every number less than 6 is a solution to this inequality.

Graph 32 (shown below is a red area. The important thing to note is that the boundary at 6 is dotted which means it is not included in the solution.

What you want is more closely related to a number line and sort of looks like this

-----o-----o-----o-----o-----o-----o-----o-----o

    -1      0      1       2      3      4      5     6

<===============================o                                                              

Explanation

The top line is the actual number line or the graph

o------- is the way it is made.

The second line are the number divisions of the number line

The third line shows which way the inequality goes and that it is open at 6. Open means that you can get close to 6 but you can't touch 6.
