Solve the equation 6=2(x+8)-5x

Answers

Answer 1

Answer:

Answer:

x = 10/3

Step-by-step explanation:

6=2(x+8)-5x

Distribute

6 = 2x+16-5x

Combine like terms

6 = 16-3x

Subtract 16 from each side

6-16 = 16-16-3x

-10 = -3x

Divide by -3

-10/-3 = -3x/-3

10/3=x

Answer 2

Answer:

Answer:

-1.43

Step-by-step explanation:

6=2(x+8)-5x

take 2 and deposit it into the parenthesis thatll give you

6=2x+16-5x

next you combine like terms so add 5x to both sides to cancel -5x then you get

6=7x+16

then you take subtract 16 on both sides which will give you

-10=7x

finally you divide 7x on both sides to get x by itself which will give you your final answer of...

-1.43=x

Is it possible to get a volume of 12000 cm3 with a surface area between 3200 cm3 and 4000 cm2?I have tried 60 x 20 x 10, 50 x 20 x 12, 100 x 12 x 10 and haven't even gotten close to the surface area that I need.

Answers

You can try with : 30 x 40 x 10. Volume is 12000 and the surface area:
2*30*40 + 2*30*10 + 2*40*10 = 2400 + 600 + 800 = 3800. This is a surface area between 3200 cm² and 4000 cm².

Jordan bikes at a speed of 8 2/3 mph. How many miles will he bike in:

45 minutes?

Answers

Answer:

13/2

Step-by-step explanation:

Keep in mind that speed*time=distance

ok so, if you convert 8 2/3 in to a improper fraction you'll get 26/3. Now we have to turn 45 minutes into a fraction so it's easier to multiply, that would be 45/60 because 1 hour has 60 minutes. Now, we would multiply 26/3 and 45/60 and get 78/12. Simplify that and get 13/2

Answer:390 miles

Step-by-step explanation:

speed*time=distance (keep that in mind)

8 2/3 is also equal to 26/3

take that number and multiply that by 45 min

45*26/3

that equall 390 miles
