A rancher raises five as many cows as horses. If he has 168 cows and horses, how many cows does he have? Complete the equations below, and then use substitution to solve. Let c represent the number of cows and h represent the number of horses Equation 1: c=_h Equation 2: c+h=_

Answers

Answer 1

Answer:

There are 28 horses and 140 cows

Step-by-step explanation:

Given

Animals: Cows and Horses

Represent Cows with c and Horses with h

For the first equation, we complete it as thus:

[tex]c = 5h[/tex]

This is so because there are 5 times as many c as h

The second equation will be completed as:

[tex]c + h = 168[/tex]

This is so because the total animals are 168

So, we have:

[tex]c = 5h[/tex]

[tex]c + h = 168[/tex]

Substitute 5h for c in the second equation

[tex]c + h = 168[/tex]

[tex]5h + h = 168[/tex]

[tex]6h= 168[/tex]

Solve for h

[tex]h = 168/6[/tex]

[tex]h = 28[/tex]

Recall that:

[tex]c = 5h[/tex]

[tex]c = 5 * 28[/tex]

[tex]c = 140[/tex]

Hence, there are 28 horses and 140 cows

Angles one and four are congruent with angle 5

Answer:

Step-by-step explanation:

∠1 , ∠4 and ∠8

A. 35
B. 85
C. 50
D. 25

Answers

Answer: B

Step-by-step explanation:

Use the exterior angle theorem, which states that the exterior angle of a triangle is equal to the sum of the two remote interior angles.

In this case: 120-x= 10+x+60

Simplifying it by combining like terms: 120-x=70+x

Solving by isolating the variable: 50= 2x, x=25

Now use what we know, which is that angle A is 35 degrees, and angle B is 60, to find out that the correct answer is B, 85 degrees.

Explain how you calculate the constant of variation.

Answers

Answer:Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.

Step-by-step explanation:The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.
