AB = x - 10, BC = x + 2, and AC = 28. Find BC.

Please help!

BC = 20

Step-by-step explanation:

AC = AB + BC

28 = x-10 + x+2

Combine like terms

28 = 2x -8

Add 8 to each side

28+8 = 2x-8+8

36 = 2x

Divide by 2

36/2 = 2x/2

18 =x

We want to find BC

BC = x+2

     =18+2

     =20

BC = 20

Step-by-step explanation:

Since line segment AC = 28, that means line segment AB and line segment BC must add up to 28:

x - 10 + x + 2 = 28

2x - 8 = 28

2x = 36

x = 18

Now we plug in x into segment BC's equation to find length of BC:

BC = x + 2

BC = 18 + 2

BC = 20

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
