Answer:
105/9
Step-by-step explanation:
180 - 132 = 48 degrees
180 - 48 - 45
= 180 - 93
= 87 degrees
<2 = 180 - 87
= 93 degrees
=> 9x - 12 = 93
=> 9x = 105
=> x = 105/9
You have the right one selected.
The answer is 2:1
To find this take each side of ABC and its corresponding side on DEF, then simplify. You can treat ratios just like fractions, so simplify them in the same way.
20:10 becomes 2:1
12:6 becomes 2:1
16:8 becomes 2:1
I'm not exactly sure of what you mean, but if the number (for example) were 2,3, and 6 you could say 2 and 6 multiply to get 6 and 6 divided by 2 would be 3 and so on. You could do this with any operation. Hope this helps, and sorry if this wasa little unclear.
To answer the problem given above, divide the difference of the prices by the original price and multiply the answer by 100%. This is,
((22450 - 19450) / 19450) x 100% = 15.42%
Therefore, the percentage markup of the new car is approximately 15.42%.
Step-by-step explanation:
20x+5=24x-1
4x=6
x=3/2
