Answer:
x = 5.5
Step-by-step explanation:
- 6-(2x-4)+x = 6-2x+4+x = 10-x
- 3(x-4) = 3x-12
- Based on the 1st and the 2nd steps, 10-x=3x-12 --> 10+12=3x+x --> 22 = 4x --> x =22/4 = 5.5
Answer:
C
Step-by-step explanation:
The parallel postulate is one of Euclid main axioms. Since it was accepted as self evident.
A is wrong, any two points can be drawn a straight line through. And straight lines exist in plane geometry.
B and D is wrong, the angle measures of a triangle must add up to 180 degrees in plane geometry.
In terms of better deal, we know that we want less money per hour. to find this we compute danny's cost per hour and martin's cost per hour of lessons and compare the 2.
Danny: 35/3 = 11.67 dollars/hour
martin: 24/2 = 12 dollars/hour
this means Danny has the better deal since his cost per hour is lower.
note that we could have also computed how many hours of lesson per dollar and in that cause the bigger number would be considered the better deal.
Danny: 3/35 = 0.086
martin: .083
this means danny has the better deal (like before!) because you get more hours of swimming lessons with 1 dollar.
although i think to choose a swim coach we have to look at his abilities as well not just how much he charges XD...sorry i got carried away.
