Now Steve, you can tap these into your calculator one by one,
get all the quotients, and mark the ones that are 4.2, all in about
3 minutes.
There are three (3) of them in the list.
One of them is 'C'. 27.3 ÷ 6.5 = 4.2
Now pick up your calculator and find the other two. You can do it !
Idk really I enjoyed this mathematics
3x-10+x+8=90
4×-2=90
4x=92
X=23
One angle is 31. 23+8
The second one is 59. 3 (23)-10
