y=3

x=5-y

x=5-3

x=2

x=2; y=3

It takes me 12 minutes to run 2 kilometers. How long will it take me to run 10,000 meters?

Therefore you multiply 12 min by 5 (because 2000m x 5 is 10000m)

Solve each question and check your solution -2(3x-4)=4(x+3)+6

agasfer [191]

Answer:

x = -1

Step-by-step explanation:

-2(3x-4)=4(x+3)+6

Distribute

-6x +8 = 4x +12 +6

Combine like terms

-6x +8 = 4x+18

Add 6x to each side

-6x+6x +8 = 4x+6x +18

8 = 10x+18

Subtract 18 from each side

8-18 =10x+18-18

-10 = 10x

Divide each side by 10

-10/10 = 10x/10

-1 =x

35.

5/9= 0.555555556

0.55555556*63=35

2/3= 0.6666666667

0.666666667*63= 42

63-35=28

42-28=14
She has 35 unplanted flowers and must plant 14 more in order to have filled 2/3 of her flower bed.
