Step-by-step explanation:

x = jars of alfalfa

y = jars of blueberry

z = jars of cover

x + y + z = 1450

x = y + 130

z = 2x

the easiest is now to turn the main equation into an expression of one variable (I am going for x).

for this let's transform the second equation

x = y × 130

y = x - 130

so now we have expressed y and z as terms of x.

back to the main equation :

x + x - 130 + 2x = 1450

4x = 1580

x = 395

he has 395 jars of alfalfa honey.

Vsevolod [243]

Answer:

D. 5 inches

Step-by-step explanation:

Given:

A frozen dinner is divided into 3 sections on a circular plate with a 12-inch diameter.

That means complete angle having 360° is divided into 3 section.

The central angle formed by the peach cobbler is 105 degrees.

The central angle formed by the pasta is 203 degrees.

<u>Question asked:</u>

What is the approximate length of the arc of the section containing the peas?

<u>Solution:</u>

The central angle formed by the peas = 360° - 105° - 203°

                                                                = 52°

Ridius,r=\frac{Dameter}{2} =\frac{12}{2} =6\ inches

As we know:

Length\ of\ arc=2\pi r\times\frac{\Theta }{360}

                        =2\times\frac{22}{7} \times6\times\frac{52}{360} \\ \\ =\frac{13728}{2520} \\ \\ =5.44\ inches

Therefore, the approximate length of the arc of the section containing the peas are 5 inches.
