Answer:

x = -26

Step-by-step explanation:

Multiply both sides by the lowest common multiple of 4 and 3, which is 12.

3(x+2) = 4(x+8)

3x + 6 = 4x + 32 --- distribute the 4 and 3

6 = x + 32 --- subtract 3x from both sides

-26 = x --- subtract 32 from both sides

x = -26

Answer: The price of the torch is 2 and 2/2.5 is 80% or 8/10th of the total price.

Step-by-step explanation:

x is the price of the battery

x + 1.50 is the price of the torch

x + (x + 1.50) is 2.50

x + (x + 1.50) = 2.50

2x = 2.50 - 1.50

2x = 1

x = 1/2

x = 0.50

The price of the torch is 2 and 2/2.5 is 80% or 8/10th of the total price.

Determine if triangle XYZ with coordinates X (1, 1), Y (5, 6), and Z (6, 2) is a right triangle. Use evidence to support your cl
Sladkaya [172]
We will use the formula for distance;

XY = \sqrt{ ( x_{Y}- x_{X} )^{2}+y_{Y}- y_{X} )^{2} } = \sqrt{ (1-5 )^{2}+(1-6 )^{2} } = \sqrt{ 16+25 } = \sqrt{41}
Applying the same formula
YZ = \sqrt{17}
XZ = \sqrt{26}

XZ^2 + YZ^2 is not equal with XY^2 which means the triangle is not right.

In order to make the triangle right, we have to take X and Z on the same x-line which means Z will be (6, 1) and Z and Y to be on the same y-line which means Y will be (6, 6). The point will be:
X(1, 1)
Y(6, 6)
Z(6, 1)

XY = \sqrt{50}
YZ = \sqrt{25}
XZ = \sqrt{25}

It means that: YZ^2+XZ^2=XY^2 and the triangle is right.
