Jimmy takes 12 minutes to run 6 times around a 600 meter track. Assuming he runs at a constant speed, how long does he take to run 1 kilometer?

Answers

Answer 1

Answer:

10/3 minutes

Step-by-step explanation:

12 minutes to run 6 times is the same as 2 minutes to run once (ratios)

so it takes 2 minutes to run once around a 600 m track

so 2 minutes/600m = x minutes/1000m

x = 2/600 * 1000 = 20/6 = 10/3

Answer 2

Answer:

10/3

Distribute the 7

[tex]3m+5=7m-7[/tex]

Subtract 3m from each side

[tex]4m-7=5[/tex]

Add 7 to each side

[tex]4m=12[/tex]

since you are subtracting a negative you can do it this way. do 7 3/5 - 6 1/5. that leaves you with 1 2/5. so in the end you will have -1 2/5

Answer:

10 + (2 x 3) {2} divided by 4 x (1/2) {3} = 2.375 (2  3/8)

Step-by-step explanation:

2 x 3 is 6 and 6 to the power of 2 is 36, and PEMDAS makes it where you divided 36 by four instead of 46 (10 + 36) divided by 4. 36 divided by 4 = 9. 10 + 9 = 19. Then 1/2 to the third power is 1/8. 19 times 1/8 = 2.375 (2  3/8)

i need help with these

Answers

Let x be the number.
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)

Answer:

twelve decreased by twice a number > 12 - 2x

8 times the sum of number and 4 > 8 (x + 4)

12 - 2x = 8 (x + 4)  then 12 - 2x = 8x + 32 (distributive property)

12 = 10x + 32 (add 2x to both sides)

-20 = 10x (subtract 32 from both sides)

x = -2 (divide both sides by 10)
