Answer:
11. 
12. 
13. 
14. 
15. 
16. 
17. 
18. 
Step-by-step explanation:
In all of them you just subtract the bottom exponent from the top exponent.
Well, if 1 mile = 1.6 kilometers and he's traveling at 18mph, then do 18 x 1.6 which = 28.8.
So, this is his current speed in kph
3 x 28.8 = 86.4
They will have traveled 86.4 kilometers
(I haven't worked with this kind of math in a while so correct me if I'm wrong!)
Answer:
it's the bottom left one
Step-by-step explanation:
Im just a kid, don't ask
So -1/4x+1/2 x would be 1/4 x because -0.25+0.5=0.25
translating 2/3 into 4/6, so we do 4/6-2/6 which would be 1/2.
:) Im an idiot lol
Answer:
C
Step-by-step explanation:
Given
m + 5 = 17 ( subtract 5 from both sides )
m = 12 ( multiply both sides by 3 to clear the fraction )
2m = 36 ( divide both sides by 2 )
m = 18 → C
X = 7. 7 x 4 = 28 and 28 + 3 = 31.
31>27
