Answer:
(1/4) hr/mile
Step-by-step explanation:
4 mph can be rewritten using other units of measurement:
Suppose we convert 'miles' to 'feet:'
Then:
4 miles 5280 ft
---------- * ------------- = 21120 ft/hr
1 hr 1 mile
Note that we could invert 4 mph and obtain
1 hr
-------- or (1/4) hr/mile
4 mi
Answer: Solve for x. Enter the solutions from least to greatest.
Lesser x: -7
Greater x- t
(7x+2+8x^4)-<span>(2x-5-8x^4)+(3x+5x^4)
(5x+7+16x^4) + (3x+5x^4)
8x + 7 + 21x^4
</span>
Divide both numbers by 13/90
13/90x = 130
÷13/90 ÷13/90
x= 900
