One 16-oz can of vegetable soup cost $1.78. Two pints of vegetable soup cost $3.17. Which option is the better deal?
aleksklad [387]
One 16 oz can of veggie soup cost $ 1.78......1.78/16 = 0.11 per oz

1 pint = 16 oz......so 2 pints = (2 * 16) = 32 oz

so 32 oz ( or 2 pints) of veggie soup cost $ 3.17.....3.17/32 = 0.10 per oz

so the better deal (the cheapest one) is the 2 pints for $ 3.17

What is the slope of this line? (The answer should be a decimal.)
Airida [17]

Answer:

10/3 = 3.3333333...

Step-by-step explanation:

Point A -> (x₁,y₁) -> (0,1)

Point B -> (x₂,y₂) -> (3,11)

Slope -> (y₂-y₁)/(x₂-x1) -> (11-1)/(3-0) -> 10/3 -> 3.3333

Therefore, the slope of the line is 3.3 repeating

Identify the x- and y- intercepts of this equation. 5 − 4 = 20
Alinara [238K]

T he x and y intercepts of the equation: 5x-4y=20 are : y-intercept is (0,-5) and x-intercept is (4,0)

So, Option D is correct.

Step-by-step explanation:

we need to identify the x and y intercepts of the equation: 5x-4y=20

Finding x-intercept

For finding x-intercept put y=0

We are given the equation:

5x-4y=20

Solving:

5x-4y=20\\5x-4(0)=20\\5x=20\\x=\frac{20}{5}\\x=4

So, x-intercept is (4,0)

Finding y-intercept

For finding y-intercept put x=0

We are given the equation:

5x-4y=20

Solving:

5x-4y=20\\5(0)-4y=20\\-4y=20\\y=\frac{20}{-4}\\y=-5

So, y-intercept is (0,-5)

the x and y intercepts of the equation: 5x-4y=20 are :y-intercept is (0,-5) and x-intercept is (4,0)

So, Option D is correct.

Tom received a $70 gift card for a cafe. He used it to buy some coffee that cost $7.73 per pound. After buying the coffee, he ha
mart [117]

Answer: He bought 6 pounds of coffee.

Step-by-step explanation:

Money he have = 70

money he used to buy = 70.00 - 23.62 = 46.38

so

7.73 dollar = 1 pound

1 dollar = 1/(7.73) = 100/773 pound

46.38 dollar = (100/773) * 46.38 = 6 pound
