Answer:
x°+2x°+(x-24)°=180°
Step-by-step explanation:
The sum of of the interior angles of all triangles add up to 180°
Adding x°, 2x°, and (x-24)° <em>will</em> equal 180
Therefore, an equation that can be used to solve for the missing angles is: x°+2x°+(x-24)°=180°
Answer:
Step-by-step explanation:
Total cost b = 23.95 + 7.65c
Answer:
-80
Step-by-step explanation:
We have: -6 =
+ 4. In order to solve for x, we need to isolate it; in order to isolate x, we have to "undo" order of operations.
The regular order of operations is PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.
Here, since we're solving for x, we need to go backwards. So, first, subtract 4 from both sides:
-6 - 4 =
+ 4 - 4 ⇒ -10 = 
Then, multiply by 8 on both sides:
-10 * 8 =
* 8 ⇒ x = -80
Thus, x = -80.
Hope this helps!
