Please help me with this question, thanks.

Answer:

8 km

Step-by-step explanation:

It is given that, the scale of a map says that 8 cm represents 5 km. We need  to find the  actual number of kilometers that is represented by 5 centimeters on the map.

8 cm = 5 km

1 cm = (8/5) km

For 5 cm, multiply (8/5) km by 5.

So,

x = 8 km

So, 8 km is represented by 5 centimeters on the map.

Answer

x= -3  -> y= -2

x= -1 -> y= -4

x= 3 -> y= -2

Step-by-step explanation:

The lines around the x in the equation is the absolute value symbol.

If you put a positive in, it stays positive.

If you put a negative in, it becomes positive.

Then solve normally.

Good luck!

Answer:

86

Step-by-step explanation:

Given:

Initial height of tree = [tex]7\dfrac{11}{12}[/tex] foot

He cut [tex]1\dfrac{2}{3}[/tex] off of tree.

To find:

The remaining height of tree after cut.

Solution:

Initial height of tree is

[tex]7\dfrac{11}{12}=\dfrac{7\times 12+11}{12}[/tex]

[tex]7\dfrac{11}{12}=\dfrac{84+11}{12}[/tex]

[tex]7\dfrac{11}{12}=\dfrac{95}{12}[/tex]

He cut [tex]1\dfrac{2}{3}[/tex] off of tree.

[tex]1\dfrac{2}{3}=\dfrac{1\times 3+2}{3}[/tex]

[tex]1\dfrac{2}{3}=\dfrac{3+2}{3}[/tex]

[tex]1\dfrac{2}{3}=\dfrac{5}{3}[/tex]

Now,

Remaining height = Initial height - cut

[tex]=\dfrac{95}{12}-\dfrac{5}{3}[/tex]

[tex]=\dfrac{95-20}{12}[/tex]

[tex]=\dfrac{75}{12}[/tex]

[tex]=\dfrac{25}{4}[/tex]

[tex]=\dfrac{6\times 4+1}{4}[/tex]

[tex]=6\dfrac{1}{4}[/tex]

Therefore, the remaining height of the tree is [tex]6\dfrac{1}{4}[/tex] foot.

Answer:

Step-by-step explanation:

a) Here we have:

"In Family A, the youngest child is 7 years younger than the oldest, who is 18"

Let's define:

Y = age of the youngest child.

O = age of the oldest child.

Then we know that:

Y = O - 7

O = 18

Then we can replace the second equation into the first one:

Y = 18 - 7 = 11.

b) Here we have:

"In Family B, the middle child is 5 years older than the youngest child."

Let's define:

Y = age of the youngest child.

M = age of the middle child.

Here we have only one equation:

M = Y + 5.

Answer:

M = Y + 5.

Answer:

area

Step-by-step explanation:

because when you are ordering sod the person that is laying it down needs measurements like 12x13 not 67 yards, that way they can get the most accurate amount

Esma will need to know area if she  needs to know the size of her yard.

Perimeter is a major property of a 2D shape , It is defined as the distance covered around the shape.It is also called the length of a triangle , rectangle and square.

It has major usage in calculation of the fencing that needs to be done , revolution that is being done etc.

It is given in the question that

Esme wants to put new sod on her front lawn.

she needs to know the size of her yard.

As by the meaning of sod , sod is grass that rolls out on the ground, almost like carpet

It will cover the complete area of the lawn and hence to buy it she will be needing to know the area rather than the perimeter.

The value of  g(x) = 2x² - 4, when g(-2) = 4

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.

Given:

g(x) = 2x² - 4

The above function is a quadratic function.

The solution of when g(-2):

Substituting the value of x = -2

 g(x) = 2x² - 4

g(x) = 2(-2)² - 4

g(x) = 8 - 4

g(x) = 4

Therefore, the value of g(-2) = 4.

Let Vc be the velocity of the car and I'm the velocity of the motorcycle. If we convert their given values, we get:

Vc = 87 km/h * 1000m / 1km * 1h / 3600s = 24.17m/s

Vm = 95 km/h * 1000m / 1km * 1h / 3600s = 26.38m/s

Since their positions are equal after 17s we can stablish that:

Where d is the initial separation distance of 54m. Solving for a, we get:

Step-by-step explanation:

-px + r = 8x -2

Step 1: Add -8x to both sides.

-px + r + -8x = 8x - 2 + -8x

-px + r - 8x = 2

Step 2: Add -r to both sides.

-px + r - 8x + -r = -2 + -r

-px - 8x = -r - 2

Step 3: Factor out variable x.

x(-p - 8) = -r - 2

Step 4: Divide both sides by -p - 8.

x(-p - 8) = -r - 2

-p - 8 -p - 8

x = r + 2
