Answer:
11 weeks
Step-by-step explanation:
30-8=22
22/2= 11
6 + 5 = 6 - (-5)
If you subtract a negative number from something, the two negatives cancel out.
C) It doesn’t satisfy either the top or bottom equations.
When we plug them into the top equation:

Simplify:

Because the statement of -23 = -15 is wrong, the solution pair is wrong for the top equation.
When we plug them into the bottom equation:

Simplify:

9 = -8 is not a valid statement, so the pair doesn't satisfy both of the equations.
Relliable = 1.5 x 30=45
speedy = 1.1 x 30 +11.5= 44.50
city = 1.25x30+8=45.50
so reliable is the cheapest
Answer:
its 3
Step-by-step explanation:
Simplifying
8 = 3x + -1
Reorder the terms:
8 = -1 + 3x
Solving
8 = -1 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
8 + -3x = -1 + 3x + -3x
Combine like terms: 3x + -3x = 0
8 + -3x = -1 + 0
8 + -3x = -1
Add '-8' to each side of the equation.
8 + -8 + -3x = -1 + -8
Combine like terms: 8 + -8 = 0
0 + -3x = -1 + -8
-3x = -1 + -8
Combine like terms: -1 + -8 = -9
-3x = -9
Divide each side by '-3'.
x = 3
Simplifying
x = 3 this took forever to type hope it helped
