Since "c" is the cost of each comedy movie we are going to multiply it by 2. so it equals to 2c. we can use "t" to represent the variable for the cost of each thriller movie. so it equals to 3t. to find the total cost you need to add. so the simplest expression is 3t + 2c

Darya [45]

Answer:

4.8 Liters

Step-by-step explanation:

Sundaes at her next birthday party. She thinks each person will eat 200 milliliters of ice cream, and there will be 24 people at her party. How many liters of ice cream should she buy

Step 1

1 person = 200ml of ice cream

24 persons = x

Cross Multiply

x = 24 × 200ml of ice cream

x = 4800 ml of ice cream

Step 2

How many liters of ice cream should she buy

We convert from Milliliters to Liters

1 milliliters= 0.001 liters

4800 millilitres = x

Cross Multiply

= 4800 × 0.001 liters

= 4.8 Liters

Therefore, she should buy 4.8 Liters of ice cream

The lines whose equations are 2x + 3y = 4 and y = mx + 6 will be perpendicular when
Natalka [10]

Answer:

These lines will be perpendicular when m =  ³⁄₂

Step-by-step explanation:

Two lines are perpendicular when the product of their gradients equal to -1. So:

m₁ * m₂ = -1

Let's get the first equation in gradient-intercept form (same as equation two).

2x + 3y = 4

3y = -2x + 4

y = -⅔x + ⁴⁄₃

We know the first gradient, and now we can find the gradient of the second line (which when multiplied will result in -1 as these lines are perpendicular). So:

-⅔ * m₂ = -1

m₂ =  ³⁄₂
