Answer:
x= 3/8 or 0.375
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7x+−12=3x+1
Step 2: Subtract 3x from both sides.
7x+−12−3x=3x+1−3x
4x+−12=1
Step 3: Add 1/2 to both sides.
4x+−12+12=1+12
4x=32
Step 4: Divide both sides by 4.
4x4=324
x=38
It would cost him $424.50
Explanation:
Let h = # of hours and y = # of life jackets
Cost = 25 + 5.50h + 6y
Cost = 25 + 5.50 (3) + 6(2)
Cost = $424.50
Answer:
x = 7
Step-by-step explanation:
180 - 141 = 39
39 + 17 = 56
8x = 56
56/8 = 7
x = 7
The answer is 1/3 and the second box is -1/3
