Answer:

64.8<em>cm</em> =<em> x</em> + <em>y</em>

The maximum sleeve length, <em>x</em>, plus the maximum allowable deviation,<em> y</em>, is 62.2<em>cm</em> = <em>x</em> - <em>y</em>

Step-by-step explanation:

The minimum sleeve length is the ideal length, <em>x</em>, minus the maximum allowable deviation,<em> y</em>.

64.8<em>cm</em> + 62.2<em>cm</em> = <em>x</em> + <em>y</em> + <em>x</em> - <em>y</em>

127.0<em>cm</em> = 2<em>x</em>

63.5<em>cm</em> =<em> x</em>

There are now two equations with two unknowns so both variable can be solved for.

Add the equations together and solve for the ideal length,<em> x</em>.

64.8<em>cm</em> = 63.5<em>cm</em> + <em>y</em>

1.3<em>cm</em> = <em>y</em>

Substitute <em>x</em> into either of the original equations and solve for<em> y</em>.

Result:

<em>x</em> = 63.5<em>cm</em>

±<em>y</em> = ±1.3<em>cm</em>

Please explain your answer as well, THANKS!!!
dusya [7]

Answer:

11,232,000

Step-by-step explanation:

The key to this problem is knowing "repetition is NOT ALLOWED".

<u>For the first 3 letters slot:</u>

For the 1st slot, we can pick any of the 26 alphabets

For the 2nd slot, we can pick any of the 25 remaining alphabets (since 1 is already taken)

For the 3rd slot, we can pick any of the 24 remaining letters (since 2 is already taken)

<u>For the three digits slot:</u>

For the 1st slot, we can pick any one of the 10 digits

For the 2nd slot, we can pick any one of the 9 digits left, since 1 is taken already

For the 3rd slot, we can pick any one of the 8 digits left, since 2 is already taken

The number of license plates, thus, would be all of these multiplied together:

26 * 25 * 24 * 10 * 9 * 8 = 11,232,000

I need help solving this equation<br> 4n-9=2(5+2n)
Nastasia [14]

First, use distributive property on the right half.

2 * 5 = 10

2 * 2n = 4n

4n - 9 = 10 + 4n

Add 9 to both sides

4n = 19 + 4n

Subtract 4n from both sides

0 = 19

But thats not true. Therefore, there is no solution.

Step two:

compound interest

A=P(1+r)^t
