Answer:
the solution is (5, 6)
Step-by-step explanation:
Please reserve " × " for representing multiplication, and " x " as a variable name.
Starting with the system
6x-5y= 0
4×-5y = -10
multiply the 2nd equation by -1. This results in the system
6x - 5y = 0
-4x + 5y = 10
and combining these two equations results in
6x - 5y = 0
-4x + 5y = 10
------------------
2x = 10, or x = 5.
Substituting 5 for x in the first equation, we get
6(5) - 5y = 0, or 5y = 30. Then y = 6, and the solution is (5, 6).
Step-by-step explanation:
Total weight of all 3 books = 2 7/16 + 1 7/8 + 1/2
Finding the common denominator,
2 7/16 = 39/16
1 7/8 = 15/8 = 30/16
1/2 = 8/16
Total = 39/16 + 30/16 + 8/16
= 77/16 = 4 13/16 pounds = 5 pounds
Total is less than 6 pounds. So, Gina can ship all 3 books.
Answer:
half of 30
Step-by-step explanation:
19 - 4 = 15
24 - 9 = 15
Answer:
x < -3 1/2 or 3.5
Step-by-step explanation:
-9x + 5 < 17
13x +25 < -1
If we add the 2 equations together, we will have
4x + 30 < 16
4x < 16 - 30
4x < -14
Divide both sides by 4
x< -14/4
x < -3 1/2 or 3.5
