Un mester popular a confectionat intru-n an 480 de fluiere,ocarine si viori.Cate instrumente de fiecare fel a confectionat mesterul,stiind ca fluiere si ocarine erau 296,iar ocarine si viori-342?

Answers

Answer 1

Answer:

138 fluiere, 158 ocarine, 184 viori

Step-by-step explanation:

given:

(1) fluiere + ocarine +viori = 480

(2) fluiere + ocarine =296

(3) ocarine + viori =342

din ecuatia (3) avem: viori= 342-ocarine

din ecuatia(2) avem : fluiere= 296-ocarine

in ecuatia (1) inlocuieste ce ai gasit ca sa fie o ecuatie doar cu necunoscuta ocarine: fluiere + ocarine +viori = 480

296-ocarine +ocarine+ 342-ocarine  =480

296+342-480 = ocarine =158

viori = 342-158 = 184

fluiere = 296-158 = 138

2 in.
4.5 in.
5 in.
9 in.

Answers

Answer:

5

Step-by-step explanation:

square root is 49 is 7

so

1 side is 7

so

original side is 7 - 2

which is

5

Answer:

The original side length was 5 in.

Step-by-step explanation:

Area of new square is (side length)^2.  Here,

that area is (x + 2)^2 = 49 in^2, and we must find x.

Taking the square root of both sides, we get:

x + 2 = +√49 = +7

Subtracting 2 from both sides yields x = -2 + 7 or x = 5

Check:  does (5 + 2)^2 = 49?  YES

A. Addition property of equality

Answers

Answer: B) Linear pair postulate

Explanation:

As the name implies, "linear pair" means the two angles combine to form a straight line of 180 degrees. Think of gluing the angles together.

As an example, let's say angle 1 was 50 degrees and angle 4 is 130 degrees. They combine to 50+130 = 180 which is a straight angle. I recommend using a protractor to help draw these angles.

Answer: he is 16

Step-by-step explanation:

Let x = Frank's age

2x+4+ = Charlie's age

x+3+ = Bob's age

9 = Bob's age

What is the equation of the line that passes through (4, 3) and (-4,-1)?

Answers

Answer:

[tex]\implies y = \dfrac{1}{2}x + 1 [/tex]

Step-by-step explanation:

Given :-

Two points (4,3) and (-4,-1)

And we need to find out the equation of the line passing through the given two points .So here we can use the two point form of the line as ,

[tex]\implies (y - y_1) = \dfrac{y_2-y_1}{x_2-x_1}(x-x_1) [/tex]

Let us take that ,

[tex](x_1,y_1)=(4,3) [/tex][tex](x_2,y_2)=(-4,-1)[/tex]

Now substitute the respective values ,

[tex]\implies (y -3) =\dfrac{3+1}{4+4}(x-4) \\\\\implies y - 3 =\dfrac{4}{8}(x-4) \\\\\implies y -3=\dfrac{1}{2}(x-4) \\\\\implies y -3=\dfrac{1}{2}x - 2 \\\\\implies y = \dfrac{1}{2}x +3-2\\\\\implies y = \dfrac{1}{2}x + 1 [/tex]

Hence the correct option is (2) .

There was 1/3 of a box of cereal left four brothers shared it evenly write an equation to represent this problem

Answers

Answer:

1/12

Step-by-step explanation:

It is given that :

Amount of cereal left = 1/3 of a box

Number of people amongst whom the box of cereal is to be divided equally = 4

Therefore, an equation representing this problem is :

[tex]$\frac{1/3}{4} = x$[/tex]

where x = is the amount of the share each brother gets.

Therefore solving the equation, we get :

[tex]$\frac{1/3}{4} = x$[/tex]

[tex]$\frac{1}{3} \times \frac{1}{4} = x$[/tex]

[tex]$\frac{1}{12}=x$[/tex]

So, each brother got 1/12th of the cereal left.

Answer:

Blue: y = x² + 3

Purple: y = (x + 4)²

Step-by-step explanation:

The parabolas are "transformed", meaning they have been shifted on the coordinate grid. All parabolas will have the equation of "y = x²", any additional transformation will add onto that.

Blue: Looking at the red parabola, its lowest point is only three units down from the blue's lowest points. Meaning the blue parabola went only three units up. So you only have to do the "+ 3" in the equation.

Purple: Like in blue, we're gonna look at the purple's lowest point and compare it to red's lowest point. The purple parabola seems to have shifted only four units to the left. Though, instead of adding onto the equation like in the blue parabola, any changes on the x-axis will be put into parenthesis. IN ADDITION, the sign will be the opposite of what it is on the coordinate grid. For example, the purple parabola is on the -4 of the x-axis. Instead of putting "(x - 4)", we put "(x + 4)".

Try the next two problems on your own. They will be similarly structured to the two answers above. If you need more help, lemme know. :)
