Answer:
Josh has 29 coins.
Step-by-step explanation:
Let Terry have x coins then Josh has x + 12 coins.
Together they have x + x + 12 coins so we can form the equation:
x + x + 12 = 46
2x + 12 = 46
2x = 46 - 12 = 34
x = 17, so Terry has 17 coins and Josh has 17 + 12 = 29 coins.
There are no real solutions.
if you subtract 20 from both sides, you get
x² = -16
You cannot find the square root of a negative number without using i, so there are no real number solutions.
To solve this problem you must apply the proccedure shown below:
1. You have the following expression:
<span>(5s/s^2-10s+25) - (25/s^2-10s+25)
2. As you can see, they have the same denominator, therefore, you can rewrite it as below:
(5s-25)/</span> (25/s^2-10s+25)
3. When you factor ir, you obtain:
5(s-25)/(s-5)(s-5)
3. Simplifying:
5/(s-5)
Answer:
a) 0.5
b) 0.75
c) 0.307
Step-by-step explanation:
We are given the following information in the question:
Number of cards in a deck = 52
Formula:
a) P(Heart or Diamond)
Total number of hearts and diamonds in a deck = 13 + 13 = 26
P( Heart or Diamond) =
b) P(Heart or Diamond or Spade)
Total number of hearts, diamonds and spades in a deck = 13 + 13 + 13 = 39
P( Heart or Diamond or Spades) =
c) P(10 or Spades)
Total number of spades in a deck = 13
Number of 10 in a deck = 4
P( 10 or Spades) =
