Answer:
x = 2.56, y = -2.63
Step-by-step explanation:
I first multiplied the second equation by two, getting
4x-6y = 26
I then subtracted the equations
4x+2y = 5
- 4x-6y = 26
--------------------
8y = -21
y = -2.63
with y solved, I plugged it into the second equation to get x:
2x-3(-2.63) = 13
2x+ 7.89 = 13
2x = 5.11
x = 2.56
I hope this helped! ;D
75 divided by 6 is 12 remainder 3 so you would need 13 cartons because you cant just leave the 3 remaining
Answer:
r = 15
Step-by-step explanation:
10(8r + 23) = 1430
Divide both sides by 10.
8r + 23 = 143
Subtract 23 from both sides.
8r = 120
Divide both sides by 8.
r = 15
Answer:
The equation would be (x-3)^2 + (y-4)^2 = 25
The Equation: -1/3 m - 7 = 5
Please watch me closely.
Add 7 to each side: -1/3 m = 12
Multiply each side by 3 : -1 m = 36
Multiply each side by -1 : m = -36
