Sebastian is going to pay ten dollars and seventy one cents ($10.71‬) for the one point four pounds of coffee.

For every pound of coffee it is seven dollars and sixty five cents ($7.65).

Instead of adding seven point sixty five (the amount per pound) one point four times (pounds of coffee), it is easier to multiply. So, let's multiply one point four and the amount per pound ($7.65).

(I am taking away the dollar sign for now! The dollar sign we can ignore for now!)

7.65 x 1.4 = 10.71

$10.71

What is the value of x in the equation one-fifthx – two-thirdsy = 30, when y = 15?

Nana76 [90]

Answer:

x = 200

Step-by-step explanation:

substitute y = 15 into the equation

$\frac{1}{5}$ x - ( $\frac{2}{3}$ × 15) = 30

$\frac{1}{5}$ x - 10 = 30 ( add 10 to both sides )

$\frac{1}{5}$ x = 40 ( multiply both sides by 5 to clear the fraction )

x = 5 × 40 = 200

Each deli sandwich made uses 1/4 pound of roast beef. Marisa started with 5 pounds of roast beef and now has 3/4 pounds left.

Iteru [2.4K]

Let us assume the number of sandwiches made by Deli = x
Amount of roast beef required for making 1 sandwich = (1/4) pound
Total amount of beef that Marisa started with = 5 pounds
Amount of beef that was left = (3/4) pounds
Then
[(1/4) * x] + (3/4) = 5
(x/4) + (3/4) = 5
(x + 3)/4 = 5
x + 3 = 5 * 4
x + 3 = 20
x = 20 - 3
= 17
So we can see from the above deduction that 17 Deli sandwiches was made by Marisa. I hope the procedure is clear enough for you to understand.
