D because two angles in this triangle are 72 degrees and there are 180 degrees in a triangle
The value increases by 70 for every two x steps, so 35 per x and starts with 0
at x=8 it is 280 or 8*35
so for x=12 the value would be 12*35=420
or by adding to the x=8 value 280+4*35=280+140=420
so the increase is 4*35=140
Answer:
Your answer is 3x = 15
Step-by-step explanation:
3x = 15
Since 3 is being multiplied by x, we divide both sides by 3. 3x/3 cancels out, and you're left with x.
15/3 = 5
x = 5
This is my take using algebraic methods.
There are 19.685 inches in 50 centimeters.
