5x = 2x-15
3x = -15
x = -5

substitute x = -5 into one of your equations
so y = 5x becomes y = 5 x -5
y= -25

x=-5 and y=-25

The weight of water is 62 and one half lb per cubic foot. How many cubic feet would be occupied by 180 lb of​ water?
inessss [21]

<u>Answer:</u>

2\frac{22}{25} cubic feet

<u>Step-by-step explanation:</u>

We are given that the weight of water is 62 and one half lb per cubic foot and we are to find the number of cubic feet that would be occupied by 180 lb of water.

For that, we will divide total amount of water by per unit weight of water:

Cubic feet occupied by 180 lb of water = \frac{180}{62.5} = = 2.88 cubic feet or 2\frac{22}{25} cubic feet

Is QRS a right triangle? Why or why not?
Yuliya22 [10]

Answer:

C

Step-by-step explanation:

Using Pythagoras' identity to determine if the triangle is right

The square of the longest side should equal the sum of the squares on the other 2 sides, that is

QS² = RS² + QR² = 8² + 5² = 64 + 25 = 89 ( take the square root of both sides )

QS = \sqrt{89}

Δ QRS is not right as QS would have to be \sqrt{89}
