Answer:
150x + 280y = 1310
Step-by-step explanation:
In case of dogs the value 10 is the minimum value. So all the values lie above 10. In total there were 100 dogs.
So for dogs, we can say number of dogs above the value of 10 pound are 100.
In case of Cats, 10 lies at the position of median. Median is the central value and 50% values lie above the median value. So number of cats with weight above 10 pound is 50.
Thus, we can conclude that there were 50 more dogs than the cats with weight over 10 pounds. So option C gives the correct answer.
Answer:
#7 is x = 51
#8 is x = 9
Step-by-step explanation:
#7 walk-through
35 + 2x + 16 + 4x + 3 = 360
35 + 16 + 3 + 2x + 4x = 360
54 + 6x = 360
6x = 306
x = 51
#8 walk-through
6x + 2 = 56
6x = 54
x = 9
Answer:
A)65 is the speed of the equation, because distance/time*speed
B)He will travel 195 Miles in 3 hours, 65*3
C)It will take around 25 minutes to reach 26 miles, since they are going 65 mph at the moment.
-2y-4=4(y-1)
Always remove the pararentheses as your first step.
-2y-4 = 4y - 4
Combine like terms.
-2y - 4y = 4 - 4
-6y = 0
Divide both sides by -6 to find y.
-6y/-6 = 0/-6
y = 0
Done
