1 yard = 3 foot. 1 Foot = 12 inches.
She has 2 yards, 3 inches which = 6 foot 3 inches. 
She needs 5 foot 9 inches. 

She has more than enough, and to work out how much she has left - 
3 inches - 9 inches = -6 inches. -0.5 foot.
6 foot - 5 foot = 1 foot. 
1 foot - 0.5 foot. = 0.5 foot. She has 0.5 foot left over

X=7 -2x+10<br> What does this equal?
mote1985 [20]

Step-by-step explanation:

Since X is given to you (in this case, it’s 7), all you have to do is plug it into the equation.

1. -2(7) + 10

When a variable or a number is directly outside a number, it means you should multiply the two numbers, no matter what.

Now that we know this: -2 * 7 = (-14) When a negative is multiplied by a positive, it turns out negative.

2. (-14) + 10: Let’s say (for instance), that I owe 14 dollars to a friend. If I pay 10 of it, how much do I owe my friend? It would be -4 because you’re still in debt, and haven’t payed your friend all of her 14 dollars back.

3. You should come up with an answer of (-4) because of all of the steps given.

If something doesn’t make sense, please make a note of it and tell me. Otherwise, have a splendid day.

meriva

Answer:

  16%

Step-by-step explanation:

The additional wage amount is $80.

The original wage amount is $500.

The ratio of the two is ...

  $80/$500 = 0.16 = 16/100

To express that ratio as a percentage, multiply it by 100%.

  0.16 × 100% = 16%

_____

It might help you to think of the percent sign (%) as a fancy way to write "per hundred" (/100). Of course, using your knowledge of place value, you know that 0.16 = sixteen hundredths = 16/100.

Realizing the meaning of the % sign, you can immediately write this as 16%.

X² - 3x + 27 = 8x - 3     аdd 3 to both sides  ⇒
           + 3          + 3
---------------------------
x² - 3x + 30 = 8x         subtract 8x from both sides ⇒<span>
    - 8x          - 8x
--------------------------
x</span>² - 11x + 30 = 0    ←  <span>standard form
</span>
