X = 4 AND x = -9
Good luck.
Salut!
Ai ca a + b + c +d = 600;
a = b + 12 => b = a-12;
a = c - 12 => c = a + 12;
d = (a+b+c)/3 => d = a;
In final, 4a = 600 => a = 150;
b = 138;
c = 162;
d = 150;
Bafta!
Answer:
8x + 5
Step-by-step explanation:
5 * (2x+1) = 10x +5
10x + 5 -2x
8x + 5
To solve this, set up a proportion where X is the amount that 120 lawn mowers would cost. It would look like

.
Then cross-multiply to get 40x = 120(4776) or 40x = 573120. Now divide each side by 40 to isolate the variable.
X = 14328.
120 lawn mowers would cost $14,328.
