Answer:
8x +5y
Step-by-step explanation:
As with any purchase, the extended amount of the bill for an item is the product of the number of items bought and the price of each of them. The total bill is the sum of the extended amounts.
On Samuel's first visit he paid ...
3x +2y . . . . . dollars for apples and spinach
On Samuel's second visit, he paid ...
5x + 3y . . . . . dollars for apples and spinach
Then the total he spent was ...
(3x +2y) +(5x +3y) = (3x +5x) +(2y +3y) = 8x +5y
Answer:
Step-by-step explanation:
You have to look up (google) the number of ml in a fluid ounce. It equals 29.57 ml approximately.
Next you must look up the number of mL in a teaspoon. The conversion factor turns out to be 4.93 mL = 1 teaspoon.
1 fluid ounce = 29.57 mL
20 fluid ounces = x mL
1/20 = 29.57 /x
x = 20*29.57
x = 591.4 mL
1 teaspoon = 4.93 mL
x teaspoons = 591.4
4.93 * x = 591.4
4.93 * x/4.93 = 591.4 / 4.93
x = 119.96
Answer:
x = -4 , x = -1
Explanation:
Multiply by x on both sides to get rid of fraction
x(x + 4/x) = x(-5)
x^2 + 4 = -5x
x^2 + 5x + 4 = 0
Factor
(x+4)(x+1) = 0
x = -4 , x = -1
