Answer:

Costul unui kilogram de nectarine = x = 6 lei

Costul kilogram de piersicilor = y = 4 lei

Step-by-step explanation:

Lăsa

Costul nectarinelor = x

Costul piersicilor = y

Prin urmare:

Dacă 4 kg de nectarine și 6 kg de piersici costă 48 de lei

4x + 6y = 48 .... Ecuația 1

3 kg de nectarine și 9 kg de piersici costă 54 de lei

3x + 9y = 54 .... Ecuația 2

Combinând ambele ecuații

4x + 6y = 48 .... Ecuația 1

3x + 9y = 54 .... Ecuația 2

Rezolvăm folosind metoda Eliminare

Înmulțiți ecuația 1 cu 3 și ecuația 2 cu 4 pentru a elimina x

12x + 18y = 144 .... Ecuația 3

12x + 36y = 216 ... Ecuația 4

Scădeți ecuația 4 din 3

-18y = -72

y = -72 / -18

y = 4 lei

Pentru a rezolva pentru x: y = 4

4x + 6y = 48 .... Ecuația 1

4x + 6 × 4 = 48.

4x + 24 = 48

4x = 48 - 24.

4x = 24

x = 24/4

x = 6 lei

Prin urmare:

Costul unui kilogram de nectarine = x = 6 lei

Costul kilogram de piersicilor = y = 4 lei

                                            Question 9)

From the line graph, taking two points

Finding the slope between  (-5, 4)  and (-6, 7)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-5,\:4\right),\:\left(x_2,\:y_2\right)=\left(-6,\:7\right)[/tex]

[tex]m=\frac{7-4}{-6-\left(-5\right)}[/tex]

[tex]m=-3[/tex]

We know that the slope-intercept of the line equation is

y = mx+b

where m is the slope and b is the y-intercept

substituting (-5, 4) and m = -3 in the slope-intercept of the line

y = mx+b

4 = -3(-5)+b

4 = 15+b

b = 4-15

b = -11

substituting b = -10 and m = -3 in the slope-intercept of the line

y = mx+b

y = -3x+(-11)

y = -3x - 11

Thus, equation is slope-intercept form will be:

y = -3x - 11

Hence, option B is true.

                                                Question 10)

From the line graph, taking two points

Finding the slope between  (4, 7)   and (-8, 1)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(4,\:7\right),\:\left(x_2,\:y_2\right)=\left(-8,\:1\right)[/tex]

[tex]m=\frac{1-7}{-8-4}[/tex]

[tex]m=\frac{1}{2}[/tex]

We know that the slope-intercept of the line equation is

y = mx+b

where m is the slope and b is the y-intercept

substituting (4, 7) and m = 1/2 in the slope-intercept of the line

y = mx+b

7 = 1/2(4)+b

7 = 2+b

b = 5

substituting b = 5 and m = 1/2 in the slope-intercept of the line

y = mx+b

y = 1/2x + 5

Thus, the equation is slope-intercept form will be:

y = 1/2x + 5

Hence, option C is true.

Ratios and Fractions

It's given 1/5 of the chocolates in a box contain nuts. The rest do not contain nuts. The portion that does not contain nuts is:

[tex]1 - \frac{1}{5}=\frac{4}{5}[/tex]

We need to calculate the ratio of the number of chocolates that contain nuts to the number of chocolates that do not contain nuts.

This can be done by dividing 1/5 by 4/5:

[tex]\displaystyle \frac{\frac{1}{5}}{\frac{4}{5}}[/tex]

Operating:

[tex]\displaystyle \frac{1}{5}\cdot\frac{5}{4}=\frac{1}{4}[/tex]

Expressing it as a ratio: 1:4

Answer: 743.30343766 . . . ft

Round it to whatever place your teacher requires it to be at.

Step-by-step explanation: So, this question can be treated as one in which you need to find the hypotenuse. If you cut the soccer field diagonally, the length and width are still the same. The two legs of our triangle are 700 ft and 250 ft. The formula for finding the hypotenuse is a²+b²=c². Input the numbers, and it becomes 700²+250²=c². 700² is 490,000 and 250² is 62,500. 490,000 + 62,500 = 552,500. This means that 552,500 is c², and in order to find c, or the hypotenuse/diagonal, we need to find the square root of 552,500. The square root of 552,500 is 743.3034376 . . . , which you can round to whatever place you need it to be at.

Answer:

C

Step-by-step explanation:

you divide 7852 by 6 to get 1308.6666666 (etc.)

then you multiply 1308 by 6 (so you take away the .6666) to get 7848

your answer is 4

Given:

Louise used 0.61 kilogram of flour each day for 3 weeks.

To find:

How many grams did Louise use in those 3 weeks?

Solution:

We know that,

1 kg = 1000 g

Flour used by Louise each day for 3 weeks = 0.61 kg

1 week = 7 days

3 week = 21 days

Flour used by Louise for 3 weeks (21 days) = (21 × 0.61) kg

                                                                        = 12.81 kg

                                                                        = (12.81 × 1000)    [ 1 kg = 1000 g]

                                                                        = 12810 g

Therefore, flour used by Louise for those 3 weeks is 12,810 grams.

Given:

Dividend = [tex]2x^3-5x^2+x+2[/tex]

Divisor = [tex]x-2[/tex]

To find:

The quotient and remainder.

Solution:

We have,

Dividend = [tex]2x^3-5x^2+x+2[/tex]

Divisor = [tex]x-2[/tex]

Divide [tex]2x^3-5x^2+x+2[/tex] by [tex]x-2[/tex] as shown in the below picture.

Dividing [tex]2x^3-5x^2+x+2[/tex] by [tex]x-2[/tex], we get

[tex]Quotient=2x^2-x-1[/tex]

[tex]Remainder=0[/tex]

Therefore, [tex]Quotient=2x^2-x-1[/tex] and [tex]Remainder=0[/tex].

Answer:

C choice.

Step-by-step explanation:

[tex]5x - 2 = - x - 20 \\ [/tex]

First, we move the same terms to the same side.

[tex]5x + x = - 20 + 2 \\ 6x = - 18[/tex]

Then we move 6 to divide - 18.

[tex]x = \frac{ - 18}{6} \\ x = - 3[/tex]

Answer:

A.

Step-by-step explanation:

To get to the answer, add both f(x) and g(x) together. This would be (2x^2 +3x -4) + (-4x^2 + 5x - 8). Remember that adding a negative number is the same as subtracting the positive of that number, for example, 3 + (-4) is the same as 3 - 4.

Answer:

-4 and + 4

Step-by-step explanation:

Two integers with a sum of 0 and product of - 16

Let the two digits = a and b

a + b = 0

a * b = - 16

If a = 4 and b = - 4 ;

CHECK:

4 + (-4) = 4 - 4 = 0

4 * (-4) = - 16

HENCE, the two integers are 4 and - 4 or - 4 and 4

Answer:

Step-by-step explanation:

This question is based on the angles of the triangle.Therefore, the angles of the triangle is 180 degree.

We need to determined the all the angles of triangle  in the figure.

In the triangle ABC,

All sides are equal, therefore it is equivalent triangle. Hence, all angles are also equal.

Therefore, angle A = 60 degree, angle B = 60 degree, angle C = 60 degree.

Now, find the angle N.

In triangle PAN, one of the angle is 69 degree, and the other is 90 degree.

We know that,

Sum of angles of the triangle is 180 degree.

Thus, angle N = 180-69-90

Angle N = 21 degree

From the figure, it is observe that,

Therefore, these are the all the angles of the given figure.
