Answer:
98% is almost 100%, so we can see that the number of problems on the test can only be 1 or 2 more than 86.

Answer:
x = 12
Step-by-step explanation:
Triangle DGH is isosceles with base angles at D and G. The external angle 134° at H is the sum of those two base angles, so we have ...
2(5x+7) = 134
5x +7 = 67 . . . . . divide by 2
5x = 60 . . . . . . . subtract 7
x = 12 . . . . . . . . divide by 5
Answer: The selling price will be $1.68
Step-by-step explanation:
If the magazine is marked-up by 12% , then you will multiply 12% by the amount of money then add it to the same amount of money.
1.50 * 12% = 0.18
1.50 + 0.18 = 1.68
Okay. This is a little tricky because your question isn't quite as clear as I would like it to be, but I can work with it nevertheless. I am going to assume that you are asking how many tenths you would get when you add 0.12 and 0.9, which are the equivalent to 12 tenths and 9 tenths. The answer to this would be 0.21, or 21 tenths, or if you want to get really technical and use the absolute correct term, 21 hundredths. If this answer was not clear, please ask! Happy home-working!
Angle ZYX=180-115=65
in triangle sum of angles =180
so
4k+5+6k+10+65=180
10k+80=180
10k=180+80=260
k=260/10
k=26
