Answer:

46 1/2 miles

Step-by-step explanation:

Given:

Distance = 15 1/2 miles

Time = 1/3 hour

Distance =?

Time = 1 hour

Distance : time

15 1/2 miles : 1/3 hour = ? miles : 1 hour

31/2 miles ÷ 1/3 bout = x miles / 1 hour

31/2 × 3/1 = x / 1

93 /2 = x

x = 93/2 miles

= 46 1/2 miles

Therefore, the bus will travel 46 1/2 miles in an hour

Answer:

x = 3.33... or 10/3

Step-by-step explanation:

3(2x - 4) = 8

distribute the 3 into the parentheses

3 • 2x = 6x

3 • -4 = -12

6x - 12 = 8

add 12 to both sides

6x = 20

divide both sides by 6

x = 3.33... or 10/3

Answer:  x = 10/3

Step-by-step explanation:

3(2x-4) = 8     apply the distributive property on the left side

6x - 12= 8       Add 12 to both sides

     +12   +12

6x = 20     Divide both sides by 6

x= 20/6 which simplifies to 10/3

Answer:

x=5

Step-by-step explanation:

4x−8=12

Step 1: Add 8 to both sides.

4x−8+8=12+8

4x=20

Step 2: Divide both sides by 4.

4x

4

=

20

x=5

Answer:

One solution, x=5.

Step-by-step explanation:

4x-8=12

To find the solution we have to find the value of x.

to find the value of x, we have to add 8 to BOTH sides.

4x-8=12   (Why add 8? because we have to do the opposite of the sign!)

   +8  +8

4x=20

Now to find X we have to ISOLATE IT.

So we take out 4, How? We do the opposite to both sides.

4/4 Cancels out

20/4 = 5

So now we know X=5

Insert in the main problem to check.

4(5)-8=12

20-8=12

12=12

Step-by-step explanation:

90 points in 6 games

90/6 = points in one game

= 15 points in one game

Answer:

15 points per game

Step-by-step explanation:

You need to divide the full amount of points (90) by the amount of games played (6) to get the amount of points per game.

90÷6=15

So 15 is the answer

Answer:

  27 13/24 inches

Step-by-step explanation:

Assuming the reported monthly growth is for the first month, the height will be ...

  22 7/8 + 4 2/3 = (22 +4) +(21/24 +16/24) = 26 +37/24 = 27 13/24

The height of the plant after the first month is 27 13/24 inches.

Answer:

2 5/12

Step-by-step explanation:

you can combine two fractions if they have the same denominator (bottom number) by adding the numerators (top numbers) and keeping the bottom number the same.

1/12+4/12 is the same as 1+4 you just put the sum over 12:

2 1/12+4/12= 2 5/12

it can also be written as 29/12

Answer:

[see below]

Step-by-step explanation:

We would need to undo the equation and preform inverse operations to get 'x' on one side. First, we need to get rid of 28 by adding 28 to each side. This would leave us with 7x on one side. Then, we wound divide each side by 7. This would leave us with 'x = 8'. If we plugged in the value, then it would satisfy the equation.

[tex]7x-28=28\\\\7x-28+28=28+28\\\\7x=56\\\\\frac{7x=56}{7}\\\\ \boxed{x=8}[/tex]

Checking the answer:

[tex]7(8)-28=28\\\\56-28=28\\\\\boxed{28=28}[/tex]

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed { \sf{x = 27}}}}}[/tex]

Step-by-step explanation:

Given, value of y = 4

To find : Value of x

[tex] \sf{3x - 4y = 65}[/tex]

plug the value of y

[tex] \dashrightarrow{ \sf{3x - 4 \times 4 = 65}}[/tex]

Multiply the numbers : 4 and 4

[tex] \dashrightarrow{ \sf{3x - 16 = 65}}[/tex]

Move 16 to right hand side and change it's sign

[tex] \dashrightarrow{ \sf{3x = 65 + 16}}[/tex]

Add the numbers : 65 and 16

[tex] \dashrightarrow{ \sf{3x = 81}}[/tex]

Divide both sides by 3

[tex] \dashrightarrow{ \sf{ \frac{3x}{3} = \frac{81}{3} }}[/tex]

Calculate

[tex] \dashrightarrow{ \sf{ x = 27}}[/tex]

Hope I helped!

Best regards! :D

Answer:

Step-by-step explanation:

-4 x 4=-16 so you add the 16 to the 65 and get 81 so then you divide the 3 from the x so it would be 81/3=27

Answer:

c.

Step-by-step explanation:

Let x be the number of adults in Tim's family. Then (17 - x) is the number of children in Tim's family.

We have $34x + $31.5(17 - x) = $558.

$34x + $31.5(17 - x) = $558

$34x + $535.5 - $31.5x = $558

$2.5x = $22.5

x = 9

Hence the answer is c.

Answer:

x = 200

Step-by-step explanation:

Given

[tex]\frac{1}{5}[/tex] x - [tex]\frac{2}{3}[/tex] y = 30 ← substitute y = 15 into the equation

[tex]\frac{1}{5}[/tex] x - [tex]\frac{2}{3}[/tex] × 15 = 30 , that is

[tex]\frac{1}{5}[/tex] x - 10 = 30 ( add 10 to both sides )

[tex]\frac{1}{5}[/tex] x = 40 ( multiply both sides by 5 to clear the fraction )

x = 200

The value of x is 200.

Here, given expression is

one-fifthx – two-thirdsy = 30,

We have to find the value of x when y = 15.

What is Mathematical expression?

Mathematical expression is a way where calculations and analytical processes should be observed.

Now, given expression is

⇒ one-fifthx – two-thirdsy = 30,

⇒ [tex]\frac{1}{5} x - \frac{2}{3} y = 30\\[/tex]

When y = 15

⇒ [tex]\frac{1}{5} x - \frac{2}{3} *15 = 30\\\\\frac{1}{5} x -2* 5 = 30\\\\\frac{1}{5} x = 30 + 10\\\\\frac{1}{5} x = 40\\\\x = 200[/tex]

Hence, The value of x is 200.
