Farmer Fran has 38 barnyard animals consisting of only chickens and goats. If these animals have 116 legs how many of each type of animal are there?
Answer: There are 20 goats and 18 chikens.
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations:
If the number of chickens is represented by C, and the number of goats is G.
Total of Animals equation:
a)C+ G = 38
Total of legs equation (since chickens have 2 legs and goats have 4 ):
b)2C + 4 G =116
If we multiply a) by 2 and subtract a) from b).
2C + 4 G =116
-
2C + 2 G =76
_________
2G = 40
Solving for G:G = 40/2
G= 20
Replacing the value of G on any equation:
a) C+ (20) =38
Solving for CC =38-20
C=18

The circumference C of a circle with radius r can be calculated using the formula
C=2πr. Which formula represents r in terms of C ?
A) r=2πC
B)r=C-2π
C)r=Cπ/2
D)r=C/2π
Answer:
D
Step-by-step explanation:
Given
C = 2πr ( isolate r by dividing both sides by 2π )
[tex]\frac{C}{2\pi }[/tex] = r → D
The circumference of a circle is defined as the distance around the circle.
The formula that represents r in terms of C is r = C/ 2π. The correct option is Option D
From the question, we are given the formula for the circumference of the circle C as :
C = 2πr
To represent in terms of C,

whats 5(3× + 4) - 3 (-2× +11)
Answer:
21x+53
Step-by-step explanation:
The simplified expression is 21x - 13.
To solve the expression 5(3x + 4) - 3(-2x + 11), follow these steps:
Distribute the 5 into the first set of parentheses:
5 × 3x = 15x
5 × 4 = 20
So, 5(3x + 4) becomes 15x + 20.
Distribute the -3 into the second set of parentheses:
-3 × -2x = 6x
-3 × 11 = -33
So, -3(-2x + 11) becomes 6x - 33.
Combine like terms:
(15x + 6x) + (20 - 33) = 21x - 13
The simplified form of the expression is 21x - 13.
A rectangle has an area of 56 square inches and a perimeter of 36 inches.
Complete the table and write a system of equations to represent the length and width of the rectangle.
Answer:
Table #1:
Length (L) | Width (W) | Area (56)
Table #2:
Length (2L) | Width (2W) | Perimeter (36)
Equation #1: L · W = 56
Equation #2: 2L + 2W = 36
Step-by-step explanation:
The following are the formulas used to find the area and the perimeter of a rectangle:
Area = L · W
Perimeter = L + L + W + W
If you group common variables, you can simplify the formula used to find the perimeter down to:
Perimeter = L + L + W + W
Perimeter = 2L + 2W (Since you're adding 2 of each)
Using these formulas, we can insert our values into them. We know that the rectangle has an area of 56 square inches meaning:
L · W = 56
We know that the rectangle has a perimeter of 36 inches meaning:
2L + 2W = 36
Answer:
Table #1:
Length (L) | Width (W) | Area (56)
Table #2:
Length (2L) | Width (2W) | Perimeter (36)
Equation #1: L · W = 56
Equation #2: 2L + 2W = 36

- 7h + 2(-4h +5) > -4h +1 +10. Solve for h
Hello.
-7h + 2(-4h + 5) > -4h + 1 + 10 ; solve for h
Our first step is to get rid of all the parenthesis. We can do this by simplifying everything out.
-7h - 8h + 10 > -4h + 11
Add like terms.
-15h + 10 > -4h + 11
Now, we must isolate our variables. We do this by moving all variables to one side and moving our other numbers to the other.
Subtract 10 from both sides. Then, add 4h to both sides.
-15h + 4h > 11 - 10
Simplify.
-11h > 1
Divide both sides by -11.
However, keep in mind that when dividing with a negative, you must change the sign. Therefore, > turns into <
-11h ÷ -11 < 1 ÷ -11
h < 1/-11
Therefore, h < -1/11
We are given with an inequality and we need to solve for h . So let's start
[tex]{:\implies \quad \sf -7h+2(-4h+5)> -4h+1+10}[/tex]
[tex]{:\implies \quad \sf -7h-8h+10> -4h+11}[/tex]
[tex]{:\implies \quad \sf -15h+10> -4h+11}[/tex]
Add 4h to both sides
[tex]{:\implies \quad \sf -15h+10+4h> \cancel{-4h}+11+\cancel{4h}}[/tex]
[tex]{:\implies \quad \sf -11h+10> 11}[/tex]
Subtracting 10 from both sides ;
[tex]{:\implies \quad \sf -11h+10-11> \cancel{11}-\cancel{11}}[/tex]
[tex]{:\implies \quad \sf -11h-1> 0}[/tex]
Adding 1 to both sides
[tex]{:\implies \quad \sf -11h-\cancel{1}+\cancel{1}> 1}[/tex]
[tex]{:\implies \quad \sf -11h>1}[/tex]
Now dividing both sides by -11 also , when we divide or multiply an inequality by a -ve , we changes the sign too. So ;
[tex]{:\implies \quad \sf \dfrac{-11h}{-11}< -\dfrac{1}{11}}[/tex]
[tex]{:\implies \quad \sf h< -\dfrac{1}{11}}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{h\in \left(-\infty ,-\dfrac{1}{11}\right)}}}[/tex]

if the 3rd and 6th terms of an h.p are 5/16 and 1/5 then ,
the 10th term is
Answer:
The tenth term is
[tex] \frac{1}{20} [/tex]
Step-by-step explanation:
The 3rd term of an AP is 1/16.
This implies that:
[tex]a + 2d = \frac{5}{16} - - - (1)[/tex]
The 6th term of an AP is 1/5.
This means that:
[tex]a + 5d = \frac{1}{5} - - - (2)[/tex]
Subtract equation 1 from equation 2.
[tex]5d - 2d = \frac{1}{5} - \frac{5}{16} [/tex]
[tex]3d = - \frac{9}{80} \\ \implies \: d = - \frac{3}{80} [/tex]
From equation (1)
[tex]a + 2( - \frac{3}{80} )= \frac{5}{16} \\ a - \frac{3}{40} = \frac{5}{16} \\ a = \frac{5}{16} + \frac{3}{40} \\ a = \frac{31}{80} [/tex]
The tenth term is:
[tex]a + 9d = \frac{31}{80} + 9( - \frac{3}{80} ) \\ = \frac{31}{80} - \frac{27}{80} = \frac{4}{80} = \frac{1}{20} [/tex]
One number is 20 greater than another. If the lesser number is subtracted from three times the greater number, the difference is 84. Find the numbers.
Answer:
The numbers are 12 and 32.
Step-by-step explanation:
x = One number
x - 20 = Another number
3x - (x - 20) = 84 (If the lesser number is subtracted from three times the greater number, the difference is 84)
Let's solve for x, this way:
3x - (x - 20) = 84
3x - x + 20 = 84
2x = 84 - 20 (Subtracting 20 at both sides)
2x = 64
x = 64/2
x = 32 ⇒ x - 20 = 12
For the given problem, by denoting the lesser number as 'x', we can form and solve an algebraic equation to find 'x=12' and 'x+20=32', which are the lesser and the greater numbers respectively.
Explanation:This problem involves the concepts of algebraic equations. Let's denote the lesser number as 'x'. Therefore, the greater number becomes 'x+20' because it is 20 more than the lesser number. The problem states that three times the greater number subtracted by the lesser number is 84. So, we can translate that into the equation: 3*(x+20) - x = 84.
Solving this equation we get: 3x + 60 - x = 84, which simplifies further to 2x + 60 = 84. Deducting 60 from both sides gives 2x = 24. Finally, dividing by 2 gives x = 12 which is the lesser number. So the greater number becomes x + 20 = 12 + 20 = 32.

amanda uses a rectangular canvas for a painting. The length is 6x - 3 centimeters. the width is 2x + 6 centmeters, and is 4/5 of the length. what are the dimensions of the canvas?
Answer: 15 4/3
Step-by-step explanation:
Final answer:
To find the dimensions of Amanda's rectangular canvas, we use the fact that the width is 4/5 of the length. By setting up an equation and solving for x, we find that x equals 3. Hence, the canvas measures 15 centimeters in length and 12 centimeters in width.
Explanation:
Amanda uses a rectangular canvas for painting where the length is given as 6x - 3 centimeters and the width is given as 2x + 6 centimeters. The width is also said to be 4/5 of the length. To find the dimensions of the canvas, we must set up an equation using the relationship between the width and the length:
The width is 4/5 of the length: (2x + 6) = (4/5)(6x - 3).Multiply both sides by 5 to clear the fraction: 5(2x + 6) = 4(6x - 3).Distribute and simplify: 10x + 30 = 24x - 12.Subtract 10x from both sides: 30 = 14x - 12.Add 12 to both sides: 42 = 14x.Divide by 14 to solve for x: x = 3.Once we have the value of x, we can find the dimensions of the canvas:
Length: 6x - 3 = 6(3) - 3 = 18 - 3 = 15 centimeters.Width: 2x + 6 = 2(3) + 6 = 6 + 6 = 12 centimeters.So, the dimensions of Amanda's canvas are 15 centimeters in length and 12 centimeters in width.
