Answer:

D. 18

Step-by-step explanation:

  • multiply both sides by 9/2, the reciprocal of 2/9.

4×(9/2)=x

  • express 4×(9/2) as a single fraction.

4×9/2=x

  • multiply 4 and 9 to get 36.

36/2=x

  • divide 36 by 2 to get 18.

18=x

  • swap sides so that all variable terms are on the left hand side.

x=18

Can someone please help me with this question
zlopas [31]

Answer:

15 kilometers

Step-by-step explanation:

So we know:

For 4 days she runs 1500 meters each day.

For 3 days she runs 3 kilometers each day.

First off, lets convert 1500 meters into kilometers.

There are 1000 meters in a kilometer, so pluggin in 1500 meters:

1500/1000 = 1.5

So for 4 days she runs 1.5 kilometers each day.

Now, to find the total kilometers, we must find multiply the 1.5 kilometers by the 4 days, the 3 kilometers by the 3 days, then add those two together.

So lets do this:

1.5*4 = 6

So she ran 6 kilometers in the first 4 days.

Next we have:

3*3 = 9

So she ran 9 kilometers in the last 3 days.

Now finally add them together:

6 + 9 = 15

So she ran a total of 15 kilometers.

Hope this helps!
