Answer: 2/3ft or C
Step-by-step explanation: Solve for b in the area of a triangle equation, A=1/2bh. Multiply 1/2 by 2 on both sides to cancel it: A(2)=bh. Divide both sides by h: =b
A = 2/5
h = 6/5
b = ?
Next, we can plug the numbers into this equation: =b
Multiply 2 and 2/5: 4/5 / 6/5
Take the reciprocal of 6/5: 4/5 x 5/6 =
÷
=
Answer:
1) x≥6

2) h > 20
Mark worked more than 20 hours.
Step-by-step explanation:
1) -20x+18≥-102
-20x≥-102-18
-20x≥-120
Dividing -20 both side
≥
x≥6

--------------------------------------
2) 14h + 25 > 305
14h > 305-25
14h > 280
Dividing 14 both side
h > 20
Mark worked more than 20 hours.
