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

Answer:

There are 96 more freshmen than juniors. the answer is D: 96

Step-by-step explanation:

28% and 22%

28 - 22 = 6

6% of 1,600 = 96

6% = 0.06

0.06 x 1,600 = 96

There are 96 more freshmen than juniors.

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].

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:

-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:

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:

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.

Answer:

The measures are 22 and 68 degrees

Step-by-step explanation:

for a right triangle, the total angle measure gives 90

Let one of the acute angle be x and the other be y

The measure of one of the acute angle is 4 times the the difference of the measure of the other angle and 5

x = 4(y-5)

Also x + y = 90

Put i into ii

4(y-5) + y = 90

4y-20 + y = 90

5y-20 = 90

5y = 90 + 20

5y = 110

y = 110/5

y = 22

But;

x = 4(y-5)

x = 4(22-5)

x = 4(17)

x = 68

The sum of the acute angles in a right-angled triangle is 90.

The acute angles are 22 and 68 degrees

Let the acute angles be x and y, such that:

[tex]\mathbf{y = 4(x - 5)}[/tex]

So, we have:

[tex]\mathbf{x + y = 90}[/tex]

Substitute 4(x - 5) for y

[tex]\mathbf{x + 4(x - 5) = 90}[/tex]

Open brackets

[tex]\mathbf{x + 4x - 20 = 90}[/tex]

Add x and 4x

[tex]\mathbf{5x - 20 = 90}[/tex]

Add 20 to both sides

[tex]\mathbf{5x = 110}[/tex]

Divide both sides by 5

[tex]\mathbf{x = 22}[/tex]

Recall that:

[tex]\mathbf{y = 4(x - 5)}[/tex]

So, we have:

[tex]\mathbf{y = 4(22 - 5)}[/tex]

[tex]\mathbf{y = 68}[/tex]

Hence, the acute angles are 22 and 68 degrees

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.

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.

Answer: 34.2 pounds

Step-by-step explanation:

First, convert 15 4/5 into an improper fraction. You should get 79/5. Then, convert 50 into a fraction that has a denominator of 5. Right now, 50= 50/1 so just multiply the top and bottom by 5 to make it 250/5. Then, subtract 79/5 from 250/5. You should get 171/5. Lastly, simplify. You should get 34.2 pounds as your final answer.
