42 cakes in 7 days, that's 42/7= 6 cakes per day
6*5=30
I would say solve each diameter equation and order them fromleast to greatest, for example
1 Venus- 7.52×10 to the power of 3
So first simplify 10 to the power of 3 which is, 1000. Then you multiply 7.52 by 1000 which gets you 7520.
So solve each equation and order it
X + x - 1 + 43 = 180. Solve for x. 2x +42 = 180 and 2x = 138. Therefore, x = 69. If x = 69, then angle H is 68 and angle G is 69. 68 + 69 + 43 = 180.
The right amount to test would be 30.
200 is to many kids and 12 is not enough.
Hope this Helps!!
105% as a decimal would be 1.05 in decimal form
