24 divided by 3 equals 8, so it’s one eighth- in a percentage that’s 12.5%. Hope this helps!

if anyone can solve this gets a $10 gamestop card i already got the codeSolve for x. Show each step of the solution. 2.5(10 - x)
schepotkina [342]

Remark

Forget the Gamestop. I'd never use it. This one is on the house.

Solution

2.5(10 - x) + 10 = 72 - 1.5x*(5x + 12)   The first step is to remove the brackets.  Be very careful you understand the bracket on the right.

25 - 2.5x + 10 = 72 - 7.5x - 18            Study the signs carefully. Collect like terms.

35 - 2.5x = 54 - 7.5x                   Add 7.5x to both sides.

35 - 2.5x + 7.5x = 54 - 7.5x + 7.5x

35 + 5x = 54                               Subtract 35 from both sides.

5x = 19                                        Divide by  5

x = 19/5

x = 3 4/5 = 3.8

Check

When you numbers are so cumbersome, you should check the answer.

<em><u>LHS</u></em>

2.5(10 - 3.8) + 10

2.5(6.2) + 10

15.5 + 10

25.5

<em><u>RHS</u></em>

72 - 1.5(5*3.8 +12)

72 - 1.5(19 + 12)

72 - 1.5(31)

72 - 46.5

25.5

<em><u>RHS = LHS</u></em> The solution checks.

The base of an isosceles triangle is 4/5. The perimeter of the triangle is 4\2\15 what is the length of either of the remaining
crimeas [40]

Answer:

  1 2/3

Step-by-step explanation:

Assuming you mean the perimeter is 4 2/15, the sum of the lengths of the two equal sides is ...

  4 2/15 - 4/5 = 4 2/15 - 12/15 = 4 -10/15

Then either of the remaining sides is half this value, or ...

  (4 -10/15)/2 = (4/2) -(1/2)(10/15) = 2 -5/15 = 1 10/15 = 1 2/3

Each of the remaining sides has length 1 2/3.
