65:160 because you add all the golf balls together (including blue) and get a total of 160 and then compaire that to 65

Answer:

The quadrilateral is a parallelogram because it has one pair of opposite sides that are both congruent and parallel ⇒ 2nd answer

Step-by-step explanation:

The formula of a distance between two points is $d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

The formula of a slope of a line is $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

∵ L (-4 , -4) and M (-1 , -5)

∴ $x_{1}$ = -4 and $x_{2}$ = -1

∴ $y_{1}$ = -4 and $y_{2}$ = -5

- Use the formula of the distance to find LM

∵ $LM=\sqrt{(-1--4)^{2}+(-5--4)^{2}}=\sqrt{9+1}$

∴ LM = $\sqrt{10}$

∵ J (1 , 2) and K (-2 , 3)

∴ $x_{1}$ = 1 and $x_{2}$ = -2

∴ $y_{1}$ = 2 and $y_{2}$ = 3

- Use the formula of the distance to find JK

∵ $JK=\sqrt{(-2-1)^{2}+(3-2)^{2}}=\sqrt{9+1}$

∴ JK = $\sqrt{10}$

- ML and JK have equal lengths

∴ LM ≅ JK

Use the formula of the slope to find the slopes of LM and JK

∵ $m_{LM}=\frac{-5--4}{-1--4}=\frac{-5+4}{-1+4}$

∴ $m_{LM}=-\frac{1}{3}$

∵ $m_{JK}=\frac{3-2}{-2-1}=\frac{1}{-3}$

∴ $m_{JK}=-\frac{1}{3}$

- ML and JK have same slopes

∴ LM // JK

∵ LM and JK are opposite sides in the quadrilateral

∵ LM ≅ JK

∵ ML // Jk

- Two opposite sides in the quadrilateral JKLM are congruent

and parallel

∴ JKLM is a parallelogram

The quadrilateral is a parallelogram because it has one pair of opposite sides that are both congruent and parallel

Solving a system of equation <br> x+5y=15 <br> -3x+2y=6

Colt1911 [192]

Answer:

(0,3)

y=3

x=0

Step-by-step explanation:

x+5y=15

-3x+2y=6

solve the equation

x=15-5y

-3x+2y=6

substitute the value of x into an equation

-3(15-5y)+2y=6

distribute

-45-15y+2y=6

add 15 to 2

-45-17y=6

add 45 from both sides

17y=51

divide both sides by 17

y=3

substitute the value of y into an equation

x=15-5•3

multiply 5 to 3

x=15-15

subtract

x=0

A square piece of tissue paper has a perimeter of 164 centimeters. How long is each side of the tissue paper?

soldier1979 [14.2K]

Answer:

s = 41 cm

Step-by-step explanation:

Since all the sides on a square are equal, we can use this formula for perimeter: P = 4s

Plugging in 164 gives us 164 = 4s, where solving for s gives us s = 41
