The values of x and y vary directly

ss7ja [257]

Answer:

y = (1/4)x

Step-by-step explanation:

"Direct variation" here signifies y = kx, where k is the constant of proportionality.

Then y = kx. Here we are to find k using the info that x = 12 and y = 3:

3 = k(12), or

k = 3/12, or k = 1/4

Then y = (1/4)x

Four glasses of milk and 2 snack bars have a total of 72 carbohydrates (carbs), and 2 glasses of milk and 3 snack bars have a t

Travka [436]

One glass of milk has 11 carbs and one snack bar has 14 carbs.

Step-by-step explanation:

Let,

Glass of milk = x

Snack bar = y

According to given statement;

4x+2y=72 Eqn 1

2x+3y=64 Eqn 2

Multiplying Eqn 2 by 2

$2(2x+3y=64)\\4x+6y=128\ \ \ Eqn\ 3$

Subtracting Eqn 1 from Eqn 3

$(4x+6y)-(4x+2y)=128-72\\4x+6y-4x-2y=56\\4y=56$

Dividing both sides by 4

$\frac{4y}{4}=\frac{56}{4}\\y=14$

Putting y=14 in Eqn 1

$4x+2(14)=72\\4x+28=72\\4x=72-28\\4x=44$

Dividing both sides by 4

$\frac{4x}{4}=\frac{44}{4}\\x=11$

One glass of milk has 11 carbs and one snack bar has 14 carbs.

Answer:

$Sales\ Price = \$9.60$

Step-by-step explanation:

Given

$Price = \$24.00$

$Discount = 60\%$

Required

Determine the sales price

First, we calculate the discount price

$Discount\ Price = Price * Discount$

$Discount\ Price = \$24.00 * 60\%$

$Discount\ Price = \$14.4$

The sales price is then calculated by subtracting the discount price from the original price of the item

$Sales\ Price = Price - Discount\ Price$

$Sales\ Price = \$24.00 - \$14.40$

$Sales\ Price = \$9.60$

Consider this sequence: -81.-54, 36, -24....

Murljashka [212]

Answer:

See below in bold.

Step-by-step explanation:

It looks like the third term should be -36.

The sequence is geometric.

The common ratio is -54/-81 = -36/-54 = -24/-36 = 2/3 .

The sum of the first 5 terms is

(-81) * (1 - (2/3)^5) / (1 - 2/3)

= -81 * 211/243 * 3

= -211.
