In 2 hours they rest for 16 minutes.

So first we should work out how long they rested for in 1 hour.

We do this by simply doing 16 (minutes of rest) divided by 2 (hours of dancing):

16 / 2 = 8

In one hour of dancing they rest for 8 minutes.

Now to work out how long they rested in 3 hours, we simply do 3 (hours of dancing) x 8 (minutes of rest per hour):

3 x 8 = 24

The couple spent 24 minutes resting in 3 hours of dancing.

Answer:

The couple rested for 24 mins in 1 hour

Step-by-step explanation:

The unit rate is 8

Answers

Answer:

0; (0, 0); 144; (3, 144)

Step-by-step explanation:

Y = distance (m)

X = time (hr)

X = 48x

If a car travels for 0 hours, it will travel __ mile(s).

y = 48x

Plug in 0 hours for x (time in hours)

y = 48(0)

Any number mutliplied by 0 equals 0

y = 0

If a car travels for 0 hours, it will travel 0 miles. This means it will pass through the point (0, 0).

(0, 0) limits our options to graphs B and D

Car travels 144 miles in 3 hours

To find how many miles it travels in 1 hour, divide 144 miles by 3 hours

144 ÷ 3 = 48

In 1 hour, a car travels 48 miles

If 48 × 3 = 144, then 48 × 4 = ?

48 × 4 = 192

When looking at graph D, there are 4 lines above 0

Counting by 48, it perfectly fits 192 by the fourth line

From (0, 0), if we move 3 units to the right we can find the third vertical line intersecting

Since the lines are counted by 48 and we are looking at the third line: 48 × 3 = 144

Use the slope to move 3 units to the right of the origin and 144 unit(s) up to the find the point (3, 144) that can be used to graph the relationship

Mauricio bought 6.75 yards of fabric for a total of $47.50
About how much was the cost per yard? Explain why your
answer is reasonable. ( brainliest included for correct answer)​

Answers

Answer:

$7.04

Step-by-step explanation:

47.50/6.75 which is about $7.04

My answer is reasonable because 47.50 is close to 49 and 6.75 is close to 7 and 49/7 is 7,  which is about 7.04.

Hope this helps :D

Answer:

About $7.04 / yard.

Step-by-step explanation:

We divide the total cost by the length of fabric.

Cost per yard = 47.50 / 6.75

= 7.037

= $7.04 to the nearest cent.

This is reasonable  because  6.75 yards is close to 7 yards and 7 * $7 = $49.

Select all equations that can result from adding these
two equations or subtracting one from the other.
equation 1: x + y = 12
equation 2: 3x - 5y = 4
(Select all that apply)

Answers

Answer:

Step-by-step explanation:

x + y = 12 ---------------(1)

3x - 5y = 4 --------------(2)

(1)*5 + (2) * 1 then,

5x + 3x = 60 + 4

8x = 64

x = 64/8

x = 8

from (1), 8 + y = 12

y = 4

apply(x,y)=(8,4) to these function.

-2x-4y = -32 no

-2x+6y=8 yes

like this

The required expression after the addition of the equations is  4x  - 4y = 16, and the expression after the subtracting of the equations is -2x +6y =  8.

Given that,
To select all equations that can result from adding these two equations or subtracting one from the other.

equation 1: x + y = 12
equation 2: 3x - 5y = 4

What is the equation?

The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.

Here,
Addition
  x  +   y  = 12
+ 3x - 5y =  4
--------------------
 4x  - 4y  = 16

Subtraction,
  x  +  y  = 12
- (3x - 5y =  4)
--------------------
  x  +  y  = 12
- 3x + 5y = -4
---------------------
-2x + 6y = 8

Thus, the required expression after the addition of the equations is  4x  - 4y = 16, and the expression after the subtracting of the equations is -2x +6y =  8.
