To answer this, we must first assume that each box weighs the same. If this is true, you would make a rate of how many pounds in 15 boxes: 45 lbs/15 boxes. From here determine the weight per box by dividing 45 by 15. This means each box is 3 pounds. Multiply this by the total number of boxes (3 x 40). This gives you a total weight of 120 pounds for 40 boxes.

Solve the following system of equations and show all work. y = 2x^2 +9x y = 4x + 25

Genrish500 [490]

Answer:

x = 5/2 thì y = 35 và x = -5 thì y = 5

Step-by-step explanation:

thay y = 4x + 25 vào phương trình y = 2x ^ 2 + 9x ta có:

4x + 25 = 2x ^ 2 + 9x

⇒2x ^ 2 + 5x - 25 = 0

⇒ x = 5/2 và x = -5

thay x = 5/2 vào phương trình y = 4x + 25 ⇒ y = 4*(5/2) + 25 = 35

thay x = -5 vào phương trình y = 4x + 25 ⇒ y = 4*(-5) + 25 = 5

the diagonals of a rhombus are 12 centimeters and 16 centimeters. what is the length of one side of the rhombus?

liq [111]

In a rhombus, the diagonals meet at right-angles, and they bisect each other, namely they cut each other in half, check the picture below.

thus we can use the pythagorean theorem to get one side, keeping in mind that, slanted as it may be, all sides in a rhombus are equal in length.
