Answer:
Emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. So the answer is 100 x 12,500 which is 1,250,000.
Step-by-step explanation:
Answer:
The correct option is C.
Step-by-step explanation:
The time in first figure is 3:00 pm and the time in second figure is 4:30 pm.
So total time taken by car is
It means total time taken by car is 1.5 hour.
The distance in first figure is 50 miles and the speed in second figure is 155 miles.
So total distance travelled by car is
It means total distance travelled by car is 105 miles.
The formula of speed is
Therefore option B represents the solution. Option B is incorrect.
Multiply both sides by 1.5 hours.
Therefore option D represents the solution. Option D is incorrect.
Divide both sides by speed.
Therefore option A represents the solution. Option A is incorrect.
Option C can not represent the solution, therefore option C is correct.
Answer:
I can only say it is not the first one
Step-by-step explanation:
I don't really know the rest of it but I know that the first one is not correct
-5
-4
-2
-1
Answer:
D -1
Step-by-step explanation:
3(x+1) = 2(x-1)
Use distributive property and get;
3x+3 = 2x-2
Add 2 to both sides,
3x+5 = 2x+4
Subtract 2x from both sides
1x+5 = 4
Subtract 5 from both sides
1x=-1
x = -1
