Answer: 40
Step-by-step explanation: 65/1.6= around 40
C is the answer! (3-(-4)=7 then 7x7 equals 49 then + 5= 54
Answer:
Total distance traveled= 21h miles
Step-by-step explanation:
You biked at 10 mph for h hours
Speed= 10 mpg
Time = h hours
Distance covered= speed*time
Distance covered= 10h miles
walked at 3mph for twice as long as I biked,
Speed= 3 mph
Time= twice as long as biked
Time= 2(h) hours
Distance= 2h*3
Distance= 6h miles
ran at 10mph for one quarter as long as I walked
Speed= 10 mph
Time= 1/4 of(2h)
Time= 1/2h hours
Distance= 1/2h*10
Distance= 5h miles
Total distance traveled
= 10h miles +6h miles+ 5h miles
Total distance traveled= 21h miles
To calculate f(x) + g(x)
=3/5x + (-3x/2)
=3/5x - 3x/2
=2(3)/2(5x)-(5x)(3x)/(5x)(2)
=(6/10x-15x^2)/10x
=(15x^2-6)/-10x
Thus the answer is D
hope it helps!
