Answer:
Step-by-step explanation:
Two of the angles are just numbers and you add them.
The third is a term and you add it along with the other two.
The total is always 180 for a triangle.
80 + 58 + 5x - 3 = 180
138 + 5x - 3 = 180 Combine on the left
135 + 5x = 180 Subtract 135 from both sides
5x = 180 - 135 Combine the right
5x = 45 Divide by 5
x = 9
The ans is choice D. since there nothing under 5x, imagine there is a 1 under. After that, you can simply cross multiply, so it would be 1(6+8x)= 2(5x). 6+8x= 10x now combine like terms so subtract 8x from both sides and divide 6 by 2 and you will get 3
1.) It would be: 12/600 * 100 = 12/6 = 2
So, your final answer is 2
2.) It would be: 20 * 0.15 = 3
So, your final answer is 3
Hope this helps!
