3 ( x ) + 55 = 85

Answer To Solving Y:

Let's solve your equation step-by-step.

3x + 55 = 85

Step 1: Subtract 55 from both sides.

3x + 55 − 55 = 85 − 55

3x = 30

Step 2: Divide both sides by 3.

3x / 3 = 30 / 3

x = 10

2 ( y ) - 5 = 95

Answer:

Let's solve your equation step-by-step.

2y − 5 = 95

Step 1: Add 5 to both sides.

2y − 5 + 5 = 95 + 5

2y = 100

Step 2: Divide both sides by 2.

2y / 2 = 100 / 2

y = 50

Find the perimeter of the triangle to the nearest whole unit.<br> 18.<br> 16.<br> 14.<br> 12.
devlian [24]

Answer:

14

Step-by-step explanation:

Perimeter of the ∆ = sum of the length of the 3 sides.

The length of the 3 sides can be calculated by using the distance formula, d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}, to find the distance between the vertices of the ∆.

The coordinates of the 3 vertices are:

(-1, 3), (2, 2), (-2, -2)

Distance between (-1, 3) and (2, 2):

Let,

(-1, 3) = (x_1, y_1)

(2, 2) = (x_2, y_2)

d = \sqrt{(2 -(-1))^2 + (2 - 3)^2}

d = \sqrt{(3)^2 + (-1)^2}

d = \sqrt{9 + 1} = \sqrt{10} = 3.2 units

Distance between (2, 2) and (-2, -2)

Let,

(2, 2) = (x_1, y_1)

(-2, -2) = (x_2, y_2)

d = \sqrt{(-2 - 2)^2 + (-2 - 2)^2}

d = \sqrt{(-4)^2 + (-4)^2}

d = \sqrt{16 + 16} = \sqrt{32} = 5.7 units

Distance between (-2, -2) and (-1, 3)

Let,

(-2, -2) = (x_1, y_1)

(-1, 3) = (x_2, y_2)

d = \sqrt{(-1 -(-2))^2 + (3 -(-2))^2}

d = \sqrt{(1)^2 + (5)^2}

d = \sqrt{1 + 25} = \sqrt{26} = 5.1 units

Perimeter of triangle = 3.2 + 5.7 + 5.1 = 14.0 units
