Answer:
x=16
Step-by-step explanation:
40x+55=695
subtract 55 from each side
40x=640
divide 640 by 40
x=16
The slope of the line is 2/3
-4x + 4 = 6
x = -.5
2x + 10 = 50
x = 20
-3x - 14 = -5
x = -3
2/3x + 2 = 5
x = 4.5
The answer is:
____________________________
5.778 mi/ h;
→ or; write as: 5 ⁷/₉ mph {"miles per hour"}.
______________________________________
Explanation:
_____________________________________
We shall solve in miles ("mi.") per hour ("h"); denoted as "mi / h" ; or sometimes, "mph".
______________________________________
Given 26 mi / 4.5 h ; we want to solve for the number of miles (mi) per unit hour (h),
________________________________
The answer is (26/ 4.5) mi / h l
______________________________
26 ÷ 4.5 = 5.7777777777777778→ Round to: 5.778 mi/ h;
→ or; write as: 5 ⁷/₉ mi /h
