Answer 1

Answer:

a

Step-by-step explanation:

a triangle has 180 degrees in total

so adding the angles altogether we get 180

set the equation up like this

6x + 3 + 75 + 60 = 180

and then combine like terms

6x + 138 = 180

then subtract

6x = 42

and then finally divide

x = 7

Answer 2

Answer:

A) 7

Step-by-step explanation:

180-60=120

120-75= 45

45-3=42

42/6= 7

A) 7

what is the answer to 5a+3b=c

Answers

Answer:

a = -0.6b + 0.2c

Step-by-step explanation:

Simplifying

5a + 3b = c

Solving

5a + 3b = c

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-3b' to each side of the equation.

5a + 3b + -3b = -3b + c

Combine like terms: 3b + -3b = 0

5a + 0 = -3b + c

5a = -3b + c

Divide each side by '5'.

a = -0.6b + 0.2c

Maximillan is cleaning shrimp. He cleans 4 shrimp every minute. Use time in minutes as the independent quantity, x, and the number of shrimp as the dependent quantity, y.

1. Identify the unit rate of this relationship. Explain what the unit rate means in terms of this situation.

2. Write an equation that demonstrates the number of shrimp cleaned per minute.

3. Is the relationship proportional or non-proportional? Explain how you can determine this using the graph and the equation.

Answers

Answer:

1. 1:4

2. y = 4 x X

3. yes

Step-by-step explanation:

1. every 1 minuet he cleans 4 shrimp

2. y is the number of shrimp and x is the time. if every miuet he cleans 4 shrimp, then that means you have to multiply the shrimp by the minuets. for example, if he spends 2 minuets, he cleans 8 shrimp because 2 x 4 = 8.

3. This is a proportional relationship because if you were to put this on a graph, it would be a strait line. for example, if you were to plot x (the time) on a line (this line would go horizontal) and y (shrimp) on the line (this line goes verticle) 1 minuet = 4 shrimp. 2 minuets = 8 shrimp. 3 minuets = 12 shrimp. 4 minuets = 16 shrimp.

i hope this helps. tell me if this is too confusing or if you need more help. have a great day :)

Find the equation of the circle that has a diameter with endpoints located at (-3, 6) and (9, 6).

Answers

Answer: [tex](x+3)^2+(y-6)^2 = 36\\\\[/tex]

==========================================================

Explanation:

If you apply the midpoint formula to the given points, you should find the midpoint is (3,6). This point represents the center of the circle. This means (h,k) = (3,6).

The radius is r = 6 because this is the distance from the center to either given endpoint. Either count out the spaces or use subtraction of the x coordinates. This works because the y coordinates are all the same.

Use those h, k and r values to plug them into the equation below

[tex](x-h)^2+(y-k)^2 = r^2\\\\(x-(-3))^2+(y-6)^2 = 6^2\\\\(x+3)^2+(y-6)^2 = 36\\\\[/tex]

which represents the equation of the circle we're after.

The graph is below.
