Answer:

90/4 can be simplified to 45/2.

Step-by-step explanation:

90 and 4 can both be divided by 2.

90 / 2 = 45

4 / 2 = 2

45/2.

This fraction, 45/2, however, cannot be simplified anymore.

Find the equation for the line shown on the right.

Answer:

$x = 8$

Step-by-step explanation:

Given

See attachment for graph

Required

The line graph

First, consider the following points on the graph.

$(x_1,y_1) = (8,0)$

$(x_2,y_2) = (8,8)$

First, calculate the slope.

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{8-0}{8-8}$

$m = \frac{8}{0}$

$m =$ undefined

Since, the slope is undefined; we simply consider only the value of x.

The line equation is:

$x = 8$

Two vertical angles are expressed as (1/2)x+12 and (3/4)x+8. Find the value of x.

JulijaS [17]

Answer:

x = 16

Step-by-step explanation:

Since vertical angles are equal, we can set these two expressions equal to each other to solve for x:

(1/2)x + 12 = (3/4)x + 8

12 = 0.25x + 8

4 = 0.25x

16 = x

Directions - For the following problem, write a paragraph proof to justify each step you make. All work must be neat,

$$ PS = \frac{4}{3} x$

Solution:

Given PRQ is a triangle.

ST is a line parallel to RQ.

$$PT = x, \ PQ = 3x, \ SR=\frac{8}{3}x$

$TQ=PQ-PT$

$TQ=3x -x=2x$

<u>Triangle proportionality theorem,</u>

<em>If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.</em>

$$\frac{PS}{SR} =\frac{PT}{TQ}$

$$\frac{PS}{\frac{8}{3} x} =\frac{x}{2x}$

Do cross multiplication, we get

$$ PS \times 2x=x \times \frac{8}{3} x$

Divide by 2x on both sides, we get

$$ PS = \frac{4}{3} x$
