Answer:
There are 15 cows and 35 chickens
Step-by-step explanation:
So first you take 20 and multiply it by two since there are two legs on each chicken. You get 40.
Then you subtract 40 from 130. You get 90.
Since the cow has double the legs of the chicken, you can count the cow as two chicken.
You divide 90 by 3. You get 30.
To get the number of chicken you divide 30 by 2 and you get 15.
You add 15 and 20 together and you get 35 chickens.
To get the number of cows you divide 30 by 2 and you get 15.
So you have your answer. 35 chicken and 15 cows.

Like drives to his grandmother’s house on Saturday. For the first three hours, he drives at a constant sped of 50 miles per hour.
Step-by-step explanation:
if you're asking for distance then,
V = s / t
50 mph = s / 3 hrs
50 mph × 3 hrs = s
150 miles = s

Does anyone know how to solve 3 by 3 linear systems?
In the system below, use equation (1) with equation (2) to eliminate x. Then use equation (1) with equation (3) to eliminate x.
x-y-2z=4 (1)
-x+3y-z=8 (2)
-2x-y-4z=-1 (3)
Answer:
x = 3, y = 3, z = - 2
Step-by-step explanation:
Given the 3 equations
x - y - 2z = 4 → (1)
- x + 3y - z = 8 → (2)
- 2x - y - 4z = - 1 → (3)
Add (1) and (2) term by term to eliminate x
2y - 3z = 12 → (4)
Multiply (1) by 2 and add to (3) to eliminate x
2x - 2y - 4z = 8 → (5)
Add (3) and (5) term by term to eliminate x
- 3y - 8z = 7 → (6)
Multiply (4) by 3 and (6) by 2
6y - 9z = 36 → (7)
- 6y - 16z = 14 → (8)
Add (7) and (8) term by term to eliminate y
- 25z = 50 ( divide both sides by - 25 )
z = - 2
Substitute z = - 2 into (7)
6y + 18 = 36 ( subtract 18 from both sides )
6y = 18 ( divide both sides by 6 )
y = 3
Substitute y = 3 and z = - 2 into (1)
x - 3 + 4 = 4
x + 1 = 4 ( subtract 1 from both sides )
x = 3
Solution is x = 3, y = 3, z = - 2

An inequality is a statement that compares two expressions that are strictly equal.
True or false
Answer:
False
Step-by-step explanation:
an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
Answer:
False.
Step-by-step explanation:
In truth, an inequality is a statement marked by any of these signs:
< less than
> greater than
[tex]\leq[/tex] less than or equal to
[tex]\geq[/tex] greater than or equal to
For example, if I wrote x < y. This means that x must always be less than y. Now, if I wrote c [tex]\geq[/tex] d, this means that c can be greater than OR equal to d. If you see a line under one of these signs, it means (sign) or equal to. So at times, they can be equal, but not strictly. That would be an equation.

What is the difference between a linear function and a nonlinear function? Explain what each looks like when represented as a table and as a graph.
Answer:
Sample Answer: A linear function has a constant rate of change, while a nonlinear function does not. For a table of values to be linear, the outputs must have a constant rate of change as the inputs increase by 1. On a graph, the function must be a straight line to be linear.
Answer:
On a graph, it is easy to remember whether a function is linear or nonlinear. Nonlinear means the graph is not a straight line. The graph of a nonlinear function is a curved line. If it is straight, then it is linear. On a table, you can determine whether a function, in tabular form, is nonlinear by observing that the jump in y varies for each unit of change in x.
Step-by-step explanation:
This is NOT the sample response. Please do not use the sample response as it is not the actual answer and teachers may find out you are not using your own responses.

Rewrite the equation by completing the square.
x^2-6x-16=0
Answer:
(x - 8)(x + 2) = 0
Step-by-step explanation:
To rewrite the equation, we need to factor:
x² - 6x - 16 = 0
(x - 8)(x + 2) = 0
The endpoints of segment MP areM(-2,-4) and P(8,11) . If K portions MP in a ratios of MK:KP= 1:4, what are the coordinates of K?
Answer:
The coordinates of k are (-2,-1)
Step-by-step explanation:
Here, we are interested in calculating the coordinates of point k.
Mathematically, we will use the internal division formula for this;
This would be;
(x,y) =( nx1 + mx2)/(m + n), (ny1 + my2)/(m + n)
where m = 1 , n = 4
x1 = -2 , x2 = 8
y1 = -4 , y2 = 11
we now make the substitutions into the formula;
(x,y) = 4(-2) + 1(-2)/(1+4) , 4(-4) + 1(11)/(4 + 1)
(x,y) = (-8-2)/5 , (-16 + 11)/5
(x,y) = -10/5 , -5/5
(x,y) = (-2, -1)

If 3x+4y=4 and 2x+y=1, then the value of 2x+3y is equal to
Answer:
3.
Step-by-step explanation:
3x + 4y = 4..........1
2x + y = 1.............2 Multiply this by 4:
8x + 4y = 4 Subtract this from equation 1:
-5x = 0
x = 0.
So substituting in equation 2:
2(0) + y = 1
y = 1.
Therefore 2x + 3y = 2(0) + 3(1) = 3.
What is the next step in solving the equation 10x+5 = -4x+47 for x after we have combined x variables to one side of the equation?
a. Once x variables have been combined we need to combine non-x variables by moving them to the other side of the equal sign.
b. Once x variables have been combined we need to divide the remaining numbers by our new x variable from combining it in step 1.
c. Since we have combined the x variables together we have completed the necessary steps to solve the equation and have the answer.
d. The problem cannot be solved for x.
Answer: A) Once x variables have been combined we need to combine non-x variables by moving them to the other side of the equal sign

Ramina found the length of two pieces of ribbon to be 47.6 inches and 39.75 inches. Which is an effective estimation strategy for finding the sum of the two lengths? Round 39.75 to 30 and 47.6 to 40, then add. Round 39.75 to 40 and 47.6 to 48, then add. Add 47.6 and 39.75, then round the answer. Subtract 39.75 from 47.6, then round the answer.
Answer:
Add 47.6 and 39.75, then round the answerStep-by-step explanation:
If Ramina found the length of two pieces of ribbon to be 47.6 inches and 39.75 inches, the effective strategy of finding the sum of the two lengths is to:
1) First is to add the two values together
47.6 + 39.75
= (47+0.6)+(39+0.75)
= (47+39)+(0.6+0.75)
= 86 + 1.35
= 87.35
2) Round up the answer to nearest whole number.
87.35 ≈ 87 (note that we couldn't round up to 88 because the values after the decimal point wasn't up to 5)
Option C is correct
Answer:
B. Round 39.75 to 40 and 47.6 to 48, then add.

How do I simplify expressions? (e.g. 8y+6(3y+7)
Answer:
26y + 42
Step-by-step explanation:
Using your example, you would break down the equation into the simplest form by combining like terms.
8y + 6(3y + 7) ← multiple what's in parenthesis by 6
8y + 18y + 42 ← Combine like terms

Sara is selling tickets to a high school festival. She sold 10 less senior tickets than junior tickets and she sold 3 times as many sophomore tickets as junior tickets (no freshman allowed). Senior tickets cost $3, junior tickets cost $5 and sophomore tickets cost $7. Sara raised $782. Write an equation to model the situation so that we can find the amount of tickets sold to seniors, juniors, and sophomores.
Answer:
[tex]29x-30=782[/tex] where x denotes number of junior tickets.
Step-by-step explanation:
Let x denotes number of junior tickets.
Sara sold 10 less senior tickets than junior tickets.
Number of senior tickets [tex]=x-10[/tex]
Sara sold 3 times as many sophomore tickets as junior tickets.
Number of sophomore tickets [tex]=3x[/tex]
Senior tickets cost $3, junior tickets cost $5 and sophomore tickets cost $7.
Total amount raised by Sara [tex]=5x+3(x-10)+7(3x)=5x+3x-30+21x=29x-30[/tex]
Sara raised $782.
So,
[tex]29x-30=782[/tex]

Step-by-step explanation:
Read the conjecture below. Select all of the true statements about this conjecture. If you multiply two numbers, then the product is greater than either number. Select all that apply. a. This conjecture is true. For example, (7)(4) = 28. The product of 28 is greater than 7 and greater than 4. b. This conjecture is false. There is a counterexample that would prove this conjecture false. c. This conjecture is false: . d. There is not enough information.
Answer:
a. This conjecture is true. For example, (7)(4) = 28. The product of 28 is greater than 7 and greater than 4
b. This conjecture is false. There is a counterexample that would prove this conjecture false.
Step-by-step explanation:
The conjecture is true because, if we multiply two numbers, then their product is greater than either number. As given in the example, 7 × 4 = 28. 28 is greater than both 7 and 4.
Also, if we multiplied a fraction by a whole number, the result would be less than one of the numbers. For example 1/2 × 4 = 2. 2 is greater than 1/2 but not 4. So, the conjecture is false.
If we multiply two fractions, the result is less than both fractions. For example 1/2 × 1/4 = 1/8. 1/8 is less than both 1/2 and 1/4. So, the conjecture is false.
The precious two examples show that there are counterexamples which prove that the conjecture is false although it is true sometimes.
