Answer: She sold 2.68kg of apples in the market

Step-by-step explanation:

Weight of pears and apples= 6.7 kg

weight of pears = 3/5 x 6.7 kg= 4.02 kg

Weight  of apples = Total weight of the fruits -  weight of pears

= 6.70kg- 4.02kg =2.68 kg

Given

y = - 8 /5 x + 2

Comparing the given equation with y = mx + c

slope (m) = - 8/5

Hope it will help :)

Answer:

-8/5

Explanation:

The equation is written in slope-intercept form, aka y = mx + b, where m is the slope and b is the y-intercept.

In slope intercept, the slope is always the number that comes before x.

In the equation y = -8/5x + 2, that number is -8/5.

Hence, the answer is -8/5.

Answer:Suppose that the equations are:

The number of people increases exponentially as the temperature increases, so we can write this as a simple exponential relation.

N(T) = a0*r^(T)

Also, the number of people that leaves the park as the temperature increases are:

M(T) = a*T + b

So the combination of these equations can say the number of people that are arriving to the park minus the number of people that are leaving, this would be:

N(T) - M(T) = total change in the park population as the temperature changes = C(T)

C(T) = a0*r^(T) - a*T - b

Step-by-step explanation:

Answer:

C- 2

I am pretty sure all this would be is :

Let c = Carlos's baseball cards

c = x + 8

Since Ben in this problem is irrelevant to Carlos, we just are using Adams cards and adding 8 onto them to find Carlos's cards since he has 8 more.

Since :

"Carlos has 8 more than Adam Write"

"Adam has x baseball cards"

So:

c = x + 8

angle E=angle N

As N and E are the corresponding angles between those equal sides D. angle E = angle N is sufficient to prove that the triangles are congruent.

Congruency is geometry that states similarities between two or more figures generally with their respective sides and angles.

We know we can prove that two triangles are congruent by sides and angles.

Given that DEF and MNO are two triangles and side DE = MN and side EF = NO, in which angles N and E lie between those two sides and therefore we can apply SAS( side angle side) congruency to prove that they are congruent.

i don't know I just need points sorry

Answer:

n = 84 and there are 24 blue cards

Step-by-step explanation:

I'm guessing you're either trying to find n or the number of blue cards.

To find the number of blue cards:

Luna has 60 red cards and the ratio of red to blue cards is 5:2.

If you divide 60 by 5 (the number of red cards divided by the ratio for red cards) you get 12, which would be 1 in the ratio. The number in the ratio for blue cards is 2, so multiply 12 by 2 and you get 24. Therefore, the number of blue cards is 24.

If the explanation is confusing (which I know it is, sorry) you can look at it like this, and this is also a check:

The ratio of red to blue cards can be written as 5/2. If you do 5 ÷ 2, you get 2.5 and if you divide 60/24, you get 2.5

To find n, the number of cards Luna has, just add the number of red cards and the number of blue cards: 60 + 24 = 84

Given:

A quadratic equation is

[tex]-6=x^2+4x-1[/tex]

To find:

The standard form of the given equation and find the value of c.

Solution:

The standard form of a quadratic equation is

[tex]ax^2+bx+c=0[/tex]               ...(i)

We have,

[tex]-6=x^2+4x-1[/tex]

It can be rewritten as

[tex]0=x^2+4x-1+6[/tex]

[tex]0=x^2+4x+5[/tex]

[tex]x^2+4x+5=0[/tex]            ...(ii)

On comparing (i) and (ii), we get

[tex]c=5[/tex]

Therefore, the value of c is equal to 5 and the correct option is C.

Answer:

= 1/x^2

Step-by-step explanation:

Possible derivation:

d/dx(-16 - 1/x + y)

Differentiate the sum term by term and factor out constants:

= d/dx(-16) - d/dx(1/x) + d/dx(y)

The derivative of -16 is zero:

= -(d/dx(1/x)) + d/dx(y) + 0

Simplify the expression:

= -(d/dx(1/x)) + d/dx(y)

Use the power rule, d/dx(x^n) = n x^(n - 1), where n = -1.

d/dx(1/x) = d/dx(x^(-1)) = -x^(-2):

= d/dx(y) - -1/x^2

Simplify the expression:

= 1/x^2 + d/dx(y)

The derivative of y is zero:

= 1/x^2 + 0

Simplify the expression:

The answer is 48 square inches as the perimeter.

The perimeter of the rectangle is 48 inches.

The whole distance that a rectangle's borders, or its sides, cover is known as its perimeter. Given that a rectangle has four sides, the perimeter of the rectangle will be equal to the total of its four sides.

Given:

The rectangle has an area of 128 square inches and a width of 8 inches.

That means, the length,

= area of the rectangle / the width of the rectangle

= 128/8

= 16 inches.

The perimeter of the rectangle,

= 2 (length + width)

= 2 (16 + 8)

= 48 inches.

Therefore, the perimeter is 48 inches.
