Answer:
5 pigs
Step-by-step explanation:
A farmhouse shelters 16 animals, some are pigs, and some are ducks. Altogether there are 42 legs. How many pigs are there?
Let us represent:
Number of pigs = x
Number of ducks = y
Our system of equations is given as:
A farmhouse shelters 16 animals, some are pigs, and some are ducks.
x + y = 16...... Equation 1
x = 16 - y
Altogether there are 42 legs.
Ducks have 2 legs(feet) , pigs have 4 legs,
4x + 2y = 42..... Equation 2
We substitute
16 - y for x in Equation 2
Hence:
4(16 - y) + 2y = 42
64 - 4y + 2y = 42
Collect like terms
- 4y + 2y = 42 - 64
-2y =- 22
y = -22/-2
y = 11 ducks
Solving for x.
x = 16 - y
x = 16 - 11
x = 5 pigs
Therefore, we have 5 pigs
The answer is 9.77 hope this helps
Answer:
(a)
Shortest Side of the trapezoid =6 yds
Longest Side =8 yds
(b)42 Square Yards
Step-by-step explanation:
<u>Part A</u>
In the Trapezoid, Width =6 yd
Since the shortest side of the playground and its width have the same dimension, then:
- Shortest Side of the trapezoid =6 yd
<u>Part B</u>
Area of the Playground
In the trapezoid
a=6 yd, b=8 yd, h=Width=6 yd
Area of a trapezoid
