Answer:

10

Step-by-step explanation:

a=3+7

a=10

10-[(10-3)-7]=

=10-[7-7]=

=10-0=

=10

The solution of expression 10 - [(a - 3) - 7] would be 10.

Given that,

The equation is,

-7 + a = 3

Now, we can simplify the equation as,

- 7 + a = 3

a - 7 = 3

Subtract 3 on both sides,

a - 3 - 7 = 0

(a - 3) - 7 = 0  .. (i)

Here, the equation to simplify is,

10 - [(a - 3) - 7]

Substitute the value from equation (i),

10 - 0

= 10

Therefore, the solution of expression is 10.

Answer:

in order to find percentages you have to multiply the base cost by the tax and then divide it by 100

Step-by-step explanation:

base price is 14500

tax rate is 9 percent

(14500 × 9 ) ÷ 100

or you can just do this

14500 × 0.09 = 1305

since multiplying by 9 then dividing by 100 is equal to multiplying by 0.09 (9/100)

14500+1305= 15805

Step-by-step explanation:

(1)

Given

A = bh ( isolate h by dividing both sides by b )

[tex]\frac{A}{b}[/tex] = h

(2)

Using the result from (1)

h = [tex]\frac{A}{b}[/tex] = [tex]\frac{45}{9}[/tex] = 5 ft

Answer:

15

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (2, 7) and (x₂, y₂ ) = (- 7, - 5)

d = [tex]\sqrt{(-7-2)^2+(-5-7)^2}[/tex]

   = [tex]\sqrt{(-9)^2+(-12)^2}[/tex]

   = [tex]\sqrt{81+144}[/tex]

   = [tex]\sqrt{225}[/tex]

    = 15

Answer:

Step-by-step explanation:

Given

f(x)= 2x – 3 and g(x) = 3/2x + 1

f(0)= 2(0)-3

f(0) = -3

g(0) = 3/2(0)+1

g(0) = 0+1

g(0) = 1

Hence since -3 < 1, this means that f(0)<g(0)

Also;

f(8)= 2(8)-3

f(8) = 16-3

f(8) = 13

g(8) = 3/2(8)+1

g(8) =12+1

g(8) = 13

This shows that g(8) = g(8)

Hence g(8) = g(8)  is a true statement

Answer:

The school is at displacement of 1 mile towards South from the home.

Step-by-step explanation:

Let the origin, O, represents the location of the school.

Now, observe the attached figure for all the displacements as:

She drove 5 miles East to shore ( to point A)

So, OA=5 miles.

Then she drove 2 miles North to Pelican's ( to point B)

So, AB=2 miles.

Then she drove 5 miles South to her friend's house ( to point C)

So, BC=5 miles.

Then she  drove 7 miles West, to point D,

So, CD=7 miles.

Then she  drove 4 miles North, to point E,

So, DE=4 miles.

Lastly, she  drove 2 miles East, to reach home (the point F)

So, EF=2 miles.

Now computing the displacements in each direction.

The displacements in the East direction=OA+EF= 5+2= 7 miles

The displacements in the West direction =CD= 7 miles

As East and West are opposite to east other, so net displacements in the East direction = 7+(-7)=0, i.e the final point F ( home) is on the vertical axis as shown.

The displacements in the North direction=AB+DE= 2+4= 6 miles

The displacements in the South direction=BC=5 miles

As North and South are opposite to east other, so net displacements in the North direction = 6+(-5)= 1 miles which means final point F ( home) is located at 1 mile towards North from the school.

Hence, the school is at displacement of 1 mile towards South from the home.

Answer:

4.5

Step-by-step explanation:

Answer with step-by-step explanation:

Lets says the number of bagels is B and the price in dollars is D.

Equation: D × 12/5 = B

1. 6 is half of a dozen, which means the price would be half of 5, 2.5

2. $50 is 10× the amount of $5, so the amount of bagels would be 10 × 12, which is 120 bagels.

Hope this helped! (brainliest please)

A Dozen mathematically means 12.

It is important to note that:

$5 = 12 bagels

          6 bagels = ?

Cross Multiply

6 bagels  x $5 / 12

= $7.50

Therefore, 6 bagels would cost $7.50

         $50 = ?

Cross multiply

$50 x 12 bagels / $5

= 120 bagels

Therfore, you can buy 120 bagels for $50
