Answer:

(1,2)

Step-by-step explanation:

6 km/h going north for 20 mins would be 1/3 of an hour so 1/3 of 6. This would mean they walked 2 kilometers north. That's your y-coordinate. They walked 6 kilometers an hour going east for 10 mins. 10 mins is 1/6 of an hour and 1 is 1/6 of 6. So 1 is your x-coordinate. You put the numbers in as (x, y).

If the swimming pool is at the origin (0, 0) then the position of the ice cream shop is (1,2) and this can be determined by using the unitary method and also by using the formula of speed.

Given :

The following steps can be used in order to determine the position of the ice cream shop:

Step 1 - Remember 1 hour is equal to 60 minutes.

Step 2 - If one hour is equal to 60 minutes then in 20 minutes there are:

[tex]\rm \dfrac{20}{60}=\dfrac{1}{3}\;hour[/tex]

Step 3 - If one hour is equal to 60 minutes then in 10 minutes there are:

[tex]\rm \dfrac{10}{60}=\dfrac{1}{6}\;hour[/tex]

Step 4 - Determine the distance travel in the north which gives the y-coordinate.

[tex]\rm Distance = 6\times \dfrac{1}{3}=2\;Km[/tex]

Step 5 - Determine the distance travel in the east which gives the x-coordinate.

[tex]\rm Distance = 6\times \dfrac{1}{6}=1\;Km[/tex]

So, the position of the ice cream shop is (1,2).

Answer:

[tex]\frac{35}{2}[/tex] - [tex]7n[/tex]

Step-by-step explanation:

7/1 − 3( 7/3n − 7/2 )

Anything divided by one gives itself.

7 - 3 ( [tex]\frac{7}{3}n - \frac{7}{2}[/tex])

Use the distributive property to multiply −3 by  [tex]\frac{7}{3}n - \frac{7}{2}[/tex])

7 - 3 × ([tex]\frac{7}{3}[/tex][tex]n[/tex] - 3 (-[tex]\frac{7}{2}[/tex])

Multiply −3 times [tex]\frac{7}{3}[/tex]

7 - 7n - 3 (-[tex]\frac{7}{2}[/tex])

Express -3 (-[tex]\frac{7}{2}[/tex]) as a single fraction.

7 - 7n + [tex]\frac{-3(-7)}{2}[/tex]

Multiply −3 and −7 to get 21.

7 - 7n + [tex]\frac{21}{2}[/tex]

Convert 7 to fraction [tex]\frac{14}{2}[/tex]

[tex]\frac{14}{2}[/tex] - 7n +  [tex]\frac{21}{2}[/tex]

Since [tex]\frac{14}{2}[/tex] and [tex]\frac{21}{2}[/tex] have the same denominator, add them by adding their numerators.

[tex]\frac{14 + 21}{2} - 7n[/tex]

Add 14 and 21 to get 35.

[tex]\frac{35}{2} - 7n[/tex]

The value of x is -(5 + 3√2).

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

7- 3√2-x=12

Now solving

7- 3√2-x=12

Subtract 7 from both side

7- 3√2-x - 7 =12 - 7

- 3√2-x = 5

Now, add 3√2 both side

-3√2 -x + 3√2 = 5 + 3√2

-x= 5 + 3√2

x= -(5 + 3√2)

Hence, the value x is -(5 + 3√2).

X= 32

Step-by-step explanation:

Answer:

X = 32

Step-by-step explanation:

If you do 24 x 4 you will get 96.

From there you have to divide 3 by 96, since 3 times x has to equal to 96. Since 24 x 4 is 96 and you need to divide 3x by 4.

After you do 96/3 you will get 32. Thus the answer being 32.
