Answer:
One solution
Step-by-step explanation:
By inspection, you can see that adding either 3x or 4x to y yields the same result of 7, meaning that x must be 0. If x is 0, y must be 7, meaning that this equation has only one solution. Hope this helps!
135000 meters and 135 kilometers
450 * 300
135000 then you convert -> 135
1. 46.93 ft/1 sec = x ft/ 1.8 sec
2. cross multiply
3. 1x= 84.474
4. x= 84.474 ft
Maybe the right two because they are more equal to each other making a better estimate.
