Just distribute -5
30u+15x-20
Don’t forget to change negative signs to positive signs if their multiplied by negatives
x = lbs
y = total cost
ABC shipping: $7 + $1x = y
XYZ shipping: $10 + $0.75x = y
We set each equation equal to the other.
$7 + $1x = $10 + $0.75x. Subtract $7 from both sides and subtract $0.75x from both sides
$0.25x = $3. Divide each side by $0.25.
x = 12 lbs
When a package is 12lbs the cost is the same.

Answer:
$244
Step-by-step explanation:
f(x) = 60x + 4 and g(x) = 2x-4
We are told to find f(g=4), when Mike makes four tables.
We have to put replace x in f(x) with the value g(x) when x is 4, like this:
f(x) = 60x + 4 // Replace x with g(x) = 2x-4
f(x) = 60(2x-4) + 4
f(x) = (120x - 240) + 4 // Solve
f(x) = (120*4 - 240) +4 // They tell us x=4
f(x) = 480 - 240 + 4 = $244
