It would cost $14.04. The equation for this would be y = 4.68x. If you multiply 3 by 4.68, you would get 14.04.

Answer:

$14.04

Step-by-step explanation:

Let

x = yards of material

y = cost

The is a linear relationship between y and x that can be represented through the following equation.

y = m.x

where,

m is the slope, representing the cost per yard

If we have any 2 points (x₁, y₁) and (x₂, y₂), we can calculate m using the following expression.

m = y₂ - y₁ / x₂ - x₁

Let's use the first 2 points.

m = ($28.08 - $23.40)/ 6 yard - 5 yard = $4.68/yard

The final equation is

y = $4.68/yard . x

If Marnie wants to buy 3 yards (x = 3 yard),

y = $4.68/yard . 3 yard = $14.04

Roman55 [17]
To do this you want to divide 110 by 5 to get 22.  Now you want to multiply 3 by 22. That means the caterer need 66 pounds of tomatoes.

Dennis decided he wanted to go to the carnival. The carnival charges $6.00 for entry and $1.50 for each ride.
myrzilka [38]

We want to create a linear equation to model the given situation.

A) c(r) = $6.00 + $1.50*r

B) 19 rides.

We know that the carnival charges $6.00 for entry plus $1.50 for each ride.

A) With the given information we can see that if you ride for r rides, then the cost equation will be:

c(r) = $6.00 + $1.50*r

Where c(r) is the cost for going to the carnival and doing r rides.

B) If you have $35.00, then we can solve:

c(r) = $35.00 =  $6.00 + $1.50*r

Now we can solve the equation for r.

$35.00 =  $6.00 + $1.50*r

$35.00 -  $6.00 = $1.50*r

$29.00 = $1.50*r

$29.00/$1.50 = r = 19.33

Rounding to the next whole number we get: r = 19

This means that with $35.00, Dennis could go to 19 rides.

When a number x is multiplied by 4, the result is 2/5. What is t he value of x
PIT_PIT [208]

The equation:

x\cdot4=\dfrac{2}{5}\ \ \ \ |\text{divide both sides by 4}\\\\x=\dfrac{2}{5}:4\\\\x=\dfrac{2}{5}\cdot\dfrac{1}{4}\\\\x=\dfrac{1}{5}\cdot\dfrac{1}{2}\\\\\boxed{x=\dfrac{1}{10}}
