In a pen of goats and chickens, there are 40 heads and 150 feet. How many goats and chickens are in the pen?

s2008m [1.1K]

Hey there!!

A chicken has 1 head and 2 feet . A goat has 1 head and 4 feet

For heads, total = 40

Let us take the number of chickens as ' x ' and goats as ' y '

x + y = 40 ------------- ( 1 )

2x + 4y = 150 ----------- ( 2 )

Multiply the first equation with 2

2x + 2y = 80

2x + 4y = 150

Subtract the first equation from the first

2y = 70

y = 35

Number of goats = 35

substitute this in other equation

x + y = 40

x + 35 = 40

x = 5

Number of chickens are 4

Hope it helps!

Answer:

Step-by-step explanation:

∠ TUL + ∠ LUV = ∠ TUV , substitute values

x + 16 + 11x = 172 , that is

12x + 16 = 172 ( subtract 16 from both sides )

12x = 156 ( divide both sides by 12 )

x = 13 → C

Compute<br><br> 8*4-4 divided by 2 +1

iragen [17]

Solution of 8 x 4 - 4 divided by 2 +1 is 9.33

<h3><u>Solution:</u></h3>

Given that,

8 x 4 - 4 divided by 2 +1

We have to compute the above equation

Let us write the given sentence mathematically:

$\rightarrow \frac{8 \times 4-4}{2 + 1}$

Let us BODMAS rule to solve the above expression

According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right.

So let us first perform multiplication of 8 and 4 in numerator

$\rightarrow \frac{32 - 4}{2 + 1}$

Now we can perform addition of 2 and 1 in denominator

$\rightarrow \frac{32-4}{3}$

Now we can perform subtraction of 4 from 32 in numerator

$\rightarrow \frac{28}{3}$

Now perform division of 28 by 3

$\rightarrow \frac{28}{3} = 9.33$

Thus solution of 8 x 4 - 4 divided by 2 +1 is 9.33
