Answer:
He has 3 pigs and 5 chickens
Step-by-step explanation:
Because pigs have 4 legs and 3 pigs would be 12 legs and then chickens have 2 legs so 5 chickens times 2 would be 10. Therefore he has 3 pigs and 5 chickens
Area of a triangle is base × height ÷2
base=8x+4 x=-4/8 x=-1/2
height=3x-4 x=4/3
A=b×h÷2
A=(-1/2×4/3)÷2
A=(-4/6)÷2
A=(-4/6)÷2/1 to divide by fractions flip the second and multiply
A=-4/6×1/2
A=-4/12
A=-1/3
Answer:
1 foot = 30.48 centimeters
1 yard = 91.44 centimeters
Step-by-step explanation:
If there are 2.54 centimeters in an inch, and 12 inches in a foot, then you need to multiply 2.54 by 12.
Their are 36 inches in a yard so you need to multiply 2.54 by 36
Answer: 3 1/3 ft^2
Step-by-step explanation:
Start by converting the inches into feet
1 ft = 12 in
4 in/1 x 1 ft/ 12 in = 4/12 ft = 1/3 ft
Now, imagine just multiply like normal for a rectangle:
Area of a rectangle = base x height
Area of rectangle = (10 ft) (1/3 ft)
Area of rectangle = 3 1/3 ft^2
