Answer:

Associative property - addition

Step-by-step explanation:

When three or more numbers are added, the sum is the same regardless of the way in  which the numbers are grouped.

(6+2) + 5 = 6 + (2+5)

8 + 5 = 6 + 7

13 = 13

If the ratio of the measure of the complement of an angle to the measure of its supplement is 1:3, find the measure of the angle
prohojiy [21]
Set up and solve an equation:

3(90-x) = (180-x).  Then  270 - 3x = 180 - x, or   270 - 180 = 2x.
                                                                               90 = 2x, so x = 45 deg.

Is this true?     3(90-45) = (180-45)?  If so, x = 45 degrees is correct.

Un jardín rectangular de 50 cm de largo por 34 m de ancho está rodeado por un camino de arena uniforme.Halla la anchura de dicho
Anastasy [175]

Answer:

5.85 m

Step-by-step explanation:

The width of the sand road can be calculated knowing its area and the dimensions of the rectangular garden as follows:

A_{g} = a.b

<u>Where:</u>

Ag: is the area of the rectangular garden

a: is the length of the rectangular garden = 50 cm = 0.5 m

b: is the width of the rectangular garden = 34 m

A_{s} = 540 m^{2}

<u>Where</u>:

As: is the area of the sand road

The relation between the area of the sand road and the area of the rectangular garden is the following:

A_{s} + A_{g} = (a+2x)*(b+2x)

540 m^{2} + 0.5m*34m = ab + 2ax + 2bx + 4x^{2}

557 m^{2} = ab + 2x(a + b) + 4x^{2}

557 m^{2} - 17m^{2} - 2x(34.5 m) - 4x^{2} = 0

540 - 69x - 4x^{2} = 0                              

By solving the above equation for x we have two solutions:

x₁ = -23.10 m

x₂ = 5.85 m

Taking the positive value, we have that the width of the sand road is 5.85 m.

I hope it helps you!
