<span>A) 2x -5y +z = 1
B) 3 y + 2z = 5
C) -24 z = 48
Those 3 equations you typed were somewhat squished together.
Did I retype those correctly?
Let me know and I'll solve it.

Given that x is the number of chains;
7(4+3) = 7 * 7 = 49 feet
You would just decide both sides by 2.
-x = -9/3 ⇨ -3
Since both numbers are negative, the product becomes a positive.
x=3
Hope this helped!
Answer:
(Sorry, I only remember how to do 1 through 7)
1. -8.86
2. 17.5
3. -6.12
4. 1.66
5. 11/24
6. 4/5
7. 14
Step-by-step explanation:
1. -5.51-3.35=-8.86
2. -59.5/-3.4=17.5
3.0.85*-7.2=-6.12
4. -0.59+2.25=1.66 (The double negatives become positive)
5. 3/8+ 1/12=11/24
6. (-24/25)/(-6/5)=4/5
7. 28/2=14

<span>A bag contains 56 marbles: 7 red, 8 green, 11 yellow, 17 brown, and 13 blue.
If a marble is chosen at random, what is the probability that the marble is green?
Probability means an occurrence of a chance
