<span>Simplifying
10 + -3(3x + -40) = -9x
Reorder the terms:
10 + -3(-40 + 3x) = -9x
10 + (-40 * -3 + 3x * -3) = -9x
10 + (120 + -9x) = -9x
Combine like terms: 10 + 120 = 130
130 + -9x = -9x
Add '9x' to each side of the equation.
130 + -9x + 9x = -9x + 9x
Combine like terms: -9x + 9x = 0
130 + 0 = -9x + 9x
130 = -9x + 9x
Combine like terms: -9x + 9x = 0
130 = 0
Solving
130 = 0
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.</span>

Step-by-step explanation:

Answer:
350 + 30W = S
Step-by-step explanation:
Since (W) represents the number of weeks he's saving money, you'd replace (W) with 14.
350 + 30(14) = S
Answer:
15,392 pencils.
Step-by-step explanation:
If a factory can make 3,848 pencils in an hour, then the factory can make 15,392 pencils in 4 hours.
Simply multiply 3,848 by 4.

Therefore, the factory can make 15,392 pencils in 4 hours.
Answer:
Step-by-step explanation:
Add 5 to both sides of the equation.
y=1/16⋅(x−3)2+5
Simplify each term.
y=(x−3)^2/16+5
Use the vertex form, y=a(x−h)2+k, to determine the values of a, h, and k. a=1/16 h =3 k=5
Since the value of a is positive, the parabola opens up.
