Answer:

11 cows and 2 chickens

Step-by-step explanation:

The required number of cows x = 30 and chickens is y = 16 .

Given that,

A farm raises cows and chickens.

The farmer has a total of 46 animals.

One day he counts the legs of all his animals and realizes he has a total of 156 legs.

We have to find,

How many cows does the farmer have.

According to the question,

Let, The number of cows = x

And the number of chickens =y.

Then,

The number of cows + The number of chickens = The farmer has a total of 46 animals.

x + y = 46

The cows has 4 legs, and the chickens has 2 legs.

He has a total of 156 legs.

Then,

The number of Cow's legs + The number of chickens legs = The total number of legs farmer have.

4x + 2y = 156

On solving both the equation,

x + y = 46

y = 46 - x

Substitute the value of y in the equation 2.

[tex]4x + 2y = 156\\\\4x + 2(46 - x) = 156\\\\4x + 96 - 2x = 156\\\\2x = 156 - 96\\\\2x = 60\\\\x = \dfrac{60}{2}\\\\x = 30[/tex]

The farmer have 30 cows.

And substitute the value of x in the equation 1,

[tex]x + y = 46\\\\30 + y = 46\\\\y = 46-30\\\\y = 16[/tex]

The farmer have 16 chickens.

Hence, The required number of cows x = 30 and chickens is y = 16 .

Answer:

1,600 dollars

Step-by-step explanation:

The easiest way to solve it is to find the dollar for 1 percent.

Since 480 accounts for 30% of the whole thing, we can do 480 divided by 30 to get 16 as 1 percent. This means that 16 times 100 percent would give us the total money spent, giving us 1,600 as our answer.

Answer:

The point (4,3) is not the solution of y ≤ -2x -5

Step-by-step explanation:

We need to tell whether (4, 3) is a solution of y ≤ -2x -5

To check if (4,3) is solution of y ≤ -2x-5 we will put the values of x and y and check if the inequality hold true or not.

Now put x = 4 and y = 3

y ≤ -2x -5

3 ≤ -2(4) -5

3 ≤ -8-5

3 ≤ -13 (False)

As 3 is not less than -13 so, inequality doesn't hold true.

Therefore the point (4,3) is not the solution of y ≤ -2x -5

Answer: 104 yards

Step-by-step explanation:

First and foremost, we need.to know that: 1 yard = 3 feet

Since she wants each balloon string to be 6 feet long and she wants to get 52 balloons. The total feet that is required for the balloon would be:

= 52 × 6

= 312 feet

Then we convert 312 feet to yard. This would be:

= 312 feet / 3 feet

= 104 yards

Answer:

x= 14/15

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x−13−3x4=562x+−13+−34x=56(2x+−34x)+(−13)=56

(Combine Like Terms)

54x+−13=5654x+−13=56

Step 2: Add 1/3 to both sides.

54x+−13+13=56+1354x=76

Step 3: Multiply both sides by 4/5.

(45)*(54X)=(45)*(76)x

=14/15

Answer: [tex]\dfrac89[/tex] cups of fertilizer is required for 3 bags of soil.

Step-by-step explanation:

Given: For every 9 bags of soil, the number of cups of fertilizers required = [tex]2\dfrac{2}{3}[/tex]

Quantity of fertilizer is proportional to the quantity of soil.

Let x be the number of cup of fertilizer required for 3 bags of soil, then

[tex]\dfrac{x}{3}=\dfrac{2\frac23}{9}\\\\\Rightarrow\ \dfrac{x}{3}=\dfrac{\dfrac83}{9}\\\\\Rightarrow\ x=\dfrac{8}{3\times9}\times3\\\\\Rightarrow\ x=\dfrac89[/tex]

Hence, [tex]\dfrac89[/tex] cups of fertilizer is required for 3 bags of soil.

Answer:

[tex]L= 117.0[/tex]

Step-by-step explanation:

Represent the sofa with S and the love seat with L.

So, we have:

[tex]S + L = 351[/tex] --- Total Cost

[tex]S = 2L[/tex]

Required

Determine the value of L

Substitute 2L for S in the first equation.

[tex]2L + L = 351[/tex]

[tex]3L= 351[/tex]

Divide both sides by 3

[tex]\frac{3L}{3}= \frac{351}{3}[/tex]

[tex]L= \frac{351}{3}[/tex]

[tex]L= 117.0[/tex]

Hence, a love seat costs 117.0

Using Graph

See attachment for graph

S is plotted on the y-axis and L is on the x-axis.

The green line represents [tex]S + L = 351[/tex] while the orange line represents [tex]S = 2L[/tex]

When the line of the graph is traced to the x-axis, we have:

[tex]L= 117.0[/tex]
