Find the value of x and justify your answer

Answer:

Step-by-step explanation:

They give you the equation and wish that you evaluate that expression by terms provided. You need only to substitue the values given into the equation

a)3(2^1)=3(2)=6

b)3(2^4)=3(16)=48

Answer:

a. 3 x 2^1 = 6

b. 3 x 2^4 = 48

Step-by-step explanation:

You basically just fill in the "t" spot with 1 and 4 and then solve it from there.

Hope this helped!!

Answer:

A

Step-by-step explanation:

The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are [tex]x[/tex] and [tex]y[/tex].

To find the constant of proportionality, all we have to do is divide any value of [tex]y[/tex] by its corresponding value of [tex]x[/tex]. Let's take the values in the first row of the table. We know that [tex]x=2[/tex] and [tex]y=12[/tex], so the constant of proportionality is [tex]\frac{y}{x}=\frac{12}{2} =6[/tex]. Hope this helps!

Answer:

1793.75 m²

Step-by-step explanation:

Given that :

Total amount of land leased = 2050 m²

Fraction of land given to brother = 1/8

Amount of land given to brother :

1/8 * 2050 = 256.25 m²

Amount of land left :

2050 m² - 256.25 m²

= 1793.75 m²

Answer:

[tex]d. \: \: \: 25 {x}^{6} [/tex]

Step-by-step explanation:

Given,

Side of the square

[tex] = 5 {x}^{3} [/tex]

Therefore, area of the square = side × side

[tex] = {5x}^{3} \times 5 {x}^{3} [/tex]

[tex] = 5 \times 5 \times {x}^{3 + 3} [/tex]

[tex] = 25 {x}^{6} [/tex]

Answer:

x=15

Step-by-step explanation:

x=√(12)²+(9)²

x=√144+81=√225

x=15units

Answer:

23 inches

Step-by-step explanation:

Let us represent

First piece = x

Second piece = y

A 92-inch is cut into two pieces.

x + y = 92

One piece is three times the length of the other.

x = 3y

Find the length of the shorter piece.

Hence:

x + y = 92

x = 3y

3y + y = 92

4y = 92

y = 92/4

y = 23 inches

Solving for x

x + y = 92

x + 23 = 92

x = 92 - 23

x = 69 inches

The shorter piece is 23 inches long.

Answer:

a. Yes

Step-by-step explanation:

Plug the values into each expression to check

y - 3 = x

4 - 3 = 1

1 = 1

This checks out

2y = 2x + 6

2(4) = 2(1) + 6

8 = 2 + 6

8 = 8

This checks out so the coordinates do indeed satisify the equations

Answer:

n = - 12

Step-by-step explanation:

n/9 + 2/3 = - 2/3

n/9 = - 2/3 - 2/3

n/9 = - 4/3

n = 9(- 4/3)

n = -36/3

n = - 12

Answer:

250

Step-by-step explanation:

V= πr^2h = π·5^2·20 ≈ 1570.79

This is the volume of the full glass so divide that by two and you get 785.4.

785.4 in terms of pi is 250.

Answer:

1 1/5 gallons is 6/5 volume of 1 gallon. Therefore, 8 1/3 * 6/5 = 25/3 * 6/5 = 150/15 = 10 lbs.

Step-by-step explanation:

Current ages:

Let Kaylan's present age be x years

Since his age is a third of his mother's present age:

mother's age * (1/3) = Kaylan's age

mother's age * (1/3) = x        

mother's age = 3x                                     [multiplying both sides by 3]

Kaylan's mother's age would be 3x years

Their ages 6 years ago:

Kaylan's age: x-6 years

Mother's age: 3x-6 years

We are told that mother's age was 5 times Kaylan's age, 6 years ago. So,

5*(Kaylan's age 6 years ago) = (Mother's age 6 years ago)

replacing the values

5(x - 6) = 3x-6

5x - 30 = 3x-6

2x - 30 = -6                                             [subtracting 3x from both sides]

2x = 24                                                    [adding 30 on both sides]

x = 12                                                       [dividing both sides by 2]

Hence, x = 12

Kaylan's present age(x) = 12 years

Mother's present age(3x) = 3*12 = 36 years

Answer:

The scale factor is 4

Step-by-step explanation:

Given

See attachment for parallelograms

Required

Determine the scale factor (k)

Using sides FG and F'G' as a point of reference:

[tex]FG = 2\ units[/tex]

[tex]F'G' = 8\ units[/tex]

The scale factor (k) is calculated as:

[tex]k = \frac{New}{Original}[/tex]

[tex]k = \frac{F'G'}{FG}[/tex]

[tex]k = \frac{8\ units}{2\ units}[/tex]

[tex]k = 4[/tex]

Answer:

a.) distributive property

b.) combining like terms

c.) cumutitative property

Answer:

B and D are correct.

Step-by-step explanation:

To find the area of a rectangle, simply multiply its length by its width. In this case, the length of the rectangle is [tex]5[/tex] m and the width of the rectangle is [tex]3[/tex] m, so its area must be [tex]5*3=15[/tex] square meters.

To find the area of a triangle, divide the product of the triangle's base and height by [tex]2[/tex]. As an algebraic expression, that would be [tex]\frac{bh}{2}[/tex], where [tex]b[/tex] and [tex]h[/tex] are the triangle's base and height, respectively. In this case, [tex]b=6[/tex] and [tex]h=5[/tex], so the triangle's area is [tex]\frac{6*5}{2}=15[/tex] square meters.

Now, let's look at the statements.

A: The triangle's area is [tex]15[/tex] square meters, not [tex]30[/tex], so A is incorrect.

B: The rectangle's area is [tex]15[/tex] square meters and the triangle's area is also [tex]15[/tex] square meters. Because the two figures have the same areas, their areas are equal, so B is correct.

C: We've already established that the two figures have equal areas, so one can't have a greater area than the other. Therefore, C is incorrect.

D: The rectangle's area is indeed [tex]15[/tex] square meters, so D is correct.

Hope this helps!

Answer:

B is correct, and D is correct

if you multiply 3 times 5 you get 15 m which is the area for the rectangle, then you have to find the area for the triangle, which you would have to multiply 6 times 5 which you get 30, then divide 30 by 2, which would be 15!

Answer:

$5647.50

Step-by-step explanation:

Formula for interest => I = Prt

substitute => I = (4500)(0.085)(3)

I = 1147.5

Add interest to our principle value => 4500 + 1147.5

Thus, our answer: $5647.50

Given:

[tex]\dfrac{2}{10}[/tex] divded by [tex]\dfrac{2}{4}[/tex].

To find:

The solution for the given division problem.

Solution:

We have, [tex]\dfrac{2}{10}[/tex] divded by [tex]\dfrac{2}{4}[/tex]. It can be written as

[tex]\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{10}\times \dfrac{4}{2}[/tex]

[tex]\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2\times 4}{10\times 2}[/tex]

[tex]\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{8}{20}[/tex]

[tex]\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{5}[/tex]

Therefore, the solution for the given division problem is [tex]\dfrac{2}{5}[/tex].
