She bought 10 apples

Step-by-step explanation:

3x + 2 = 14

why i did this

because she bought 2 times the amount of bananas, it should be x + 2x = 3x

then i added two because she bought two extra apples

so 3x+2 = 14

subtract 2

3x = 12

x = 4

So now we substitute x in apples

2x +2 = # of apples

8 +2 = 10

check

10 - 2 = 8

8/2 = 4

4 = # of bananas

Answer:

Anna bought 4 bananas and 10 apples.

Step-by-step explanation:

System of Equations

Let's call the following variables:

x = number of bananas Anna buys

y = number of apples Anna buys

She buys 2 more apples than twice the number of bananas, thus:

y = 2x + 2      [1]

Anna bought 14 fruits in total, thus:

x + y = 14      [2]

Substituting [1] in [2]:

x + 2x + 2 = 14

Simplifying:

3x = 12

Dividing by 3:

x = 4

Substituting in [1]:

y = 2*4+2 = 10

Anna bought 4 bananas and 10 apples.

Answer:

x = 20°

Step-by-step explanation:

An equilateral triangle has three equal angles of 60° each.

Since ∆BCD is an equilateral triangle, it follows that:

<CBD = <BCD = <CDB = 60°

m<ACD = 40° + <BCD

m<ACD = 40° + 60° (substitution)

m<ACD = 100°

x + m<ACD + CDB = 180° (sum of triangle)

x + 100° + 60° = 180° (substitution)

x + 160 = 180

Subtract 160 from each side

x = 180 - 160

x = 20°

Step-by-step explanation:

Answer:

He can buy 5 of the $3 nut and 1 of the $5 nuts.

5x3=15

5x1=5

15+5=20 and that’s less than 24.

So Jim can use $20 to buy the $3 one 5 times and the $5 one 1 time.

Answer:

x = - 5, x = 3

Step-by-step explanation:

Given

x² + 2x - 15 = 0

Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)

The factors are + 5 and - 3 , since

5 × - 3 = - 15 and 5 - 3 = + 2, so

x² + 2x - 15 = 0

(x + 5)(x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x - 3 = 0 ⇒ x = 3

Answer:

Volume is 718 cm^3

Step-by-step explanation:

We need to get the radius of cylinder A

From the base area,

we have that;

A = pi * r^2

18 = 3.142 * r^2

r^2 = 18/3.142

r^2 = 5.73

r= √5.73

r = 2.39

If two shapes are similar, we have the ratio of their corresponding sides equal;

Thus;

2.39/5 = x/10

x = (10 * 2.39)/5

x = 4.78 cm

To get the volume, we use the formula

V = pi * r^2 * h

V = 3.142 * 4.78^2 * 10

V = 717.8 cm^3

This is approximately 718 cm^3

d)  21 / 6 = x / 20

    7 / 3 = x / 20    

    2x = 140

Answer:

m<DEF = 8y - 6

Step-by-step explanation:

Given that: DEG = [tex](3y +4)^{o}[/tex], and FEG = [tex](5y-10)^{o}[/tex].

The given triangle is an isosceles triangle with sides DE ≅ DF.

But,

m<DEF = DEG + FEG

            =  [tex](3y +4)^{o}[/tex] + [tex](5y-10)^{o}[/tex]

            = 3y + 4 + 5y - 10

            = 8y - 6

m<DEF = 8y - 6

Therefore, the measure of < DEF is 8y - 6.

Answer:

The length of the missing side is:  x = 15

Thus, option A) is the correct option.

Step-by-step explanation:

Let 'x' be the missing sides.

From the given triangle, it is clear that the segment cuts the sides into proportional ratios such 9 : 12 and x : 20 respectively.

Therefore,

9 : 12 = x : 20

9/12 = x/20

cross multiplication

12 × x = 20 × 9

12x = 180

divide both sides by 12

12x/12 = 180/12

x = 15

Therefore, the length of the missing side is:  x = 15

Thus, option A) is the correct option.

Answer:

Step-by-step explanation:

A function is a mathematical device that converts one value to another in a known way. We can think of it as a machine. You feed the machine an input, it does some calculations on it, and then gives you back another value - the result of the calculations. The set of allowable inputs to a given function is called the domain of the function

Answer:

Heres some sentences.

Step-by-step explanation:

A function works like a machine. Numbers are put into the machine one at a time, and then the rule performs the operation(s) on each input to determine each output.

The equation of the blue line will be

y = 4x -3

The equation of the line that passes through the points (1, 1) and (2, 5) is y = 4x - 3.

We have,

To find the equation of the line that passes through the coordinates (1, 1) and (2, 5), we can use the point-slope form of the equation of a line.

The point-slope form of the equation is:

y - y1 = m(x - x1)

Where (x1, y1) represents one of the given points on the line, and m represents the slope of the line.

First, let's calculate the slope (m) using the given coordinates:

m = (y2 - y1) / (x2 - x1) = (5 - 1) / (2 - 1) = 4 / 1 = 4

Now, we can choose either of the given points and substitute its coordinates into the point-slope form. Let's use (1, 1):

y - 1 = 4(x - 1)

Simplifying the equation:

y - 1 = 4x - 4

y = 4x - 3

Therefore,

The equation of the line that passes through the points (1, 1) and (2, 5) is y = 4x - 3.

Answer:

An equilateral triangle has all its 3 angles the same.

Hope this helped. :)  

Equilateral triangle:

An equilateral triangle is a triangle having three equal sides, or what is sometimes referred to as a "regular" triangle. Because all three sides of an isosceles triangle are equal, an equilateral triangle is a particular case of an isosceles triangle.

Additionally, an equilateral triangle has three equal angles of 60 degrees.

Equilateral Triangle Perimeter:

In geometry, any polygon's perimeter is equal to the sum of its sides. The perimeter of an equilateral triangle is equal to the sum of its three sides.

In the event that ABC is an equilateral triangle, then its perimeter is;

Perimeter = AB + BC + AC

P = a + a + a

P = 3a    [where "a" is the triangle's side length.]
