What is the solution to this problem: (4/9)/(2/3)/(5/6)

valentina_108 [34]

(4/9)/(2/3)/(5/6)

First, invert and multiply. / Your problem should look like: $\frac{4}{9} \\ \frac{2}{3}$ × $\frac{6}{5}$
Second, invert and multiply. / Your problem should look like: $\frac{4}{9}$ × $\frac{3}{2}$ × $\frac{6}{5}$
Third, apply this rule: $\frac{a}{b}$ × $\frac{c}{d}$ . / Your problem should look like: $\frac{4 x 3 x 6}{9 x 2 x 5}$
Fourth, simplify 4 × 3 × 6 to 72. / Your problem should look like: $\frac{72}{9x2x5}$
Fifth, simplify 9 × 2 × 5 to 90. / Your problem should look like: $\frac{72}{90}$
Sixth, simplify. / Your problem should look like: $\frac{4}{5}$

Original answer: $\frac{4}{5}$
Answer as decimal: 0.8

Z is centroid of triangle RST. What is RW, if RV=4x+3, WS=5x-1, and VT=2x+9?

vaieri [72.5K]

Given that Z is the centroid of a triangle RST. This means that Z is the point of intersection of the three medians of the triangle.

So,W is the midpoint of RSV is the midpoint of RTWe are given that:RV = 4x + 3 and VT = 2x + 9

Since V is the midpoint, then:RV = VT4x + 3 = 2x + 94x - 2x = 9 - 32x = 6x = 3

Now put the value of x in WS = 5x-1WS = 5x-1WS = 5(3) - 1 WS = 15 - 1 = 14WS = 14

Since W is the midpoint of RS, therefore RW = WSand WS = 14Therefore:
RW = 14

What are the numerical measures of each angle in the diagram? 1 and 3 measure degrees. 2 and 4 measure degrees. (3x - 1)º (2x +

Tanya [424]

Answer:

Step-by-step explanation:

In the diagram shown, the measure of angle 1 is oppositely directed to angle 2 and oppositely directed angles are equal.

Hence <1 = <3

Given < 1 = 3x-1 and <3 = 2x+9

Hence 3x-1 = 2x+9

collect like terms

3x-2x = 9+1

x = 10°

Since <1 = 3x-1

on substituting x = 10

<1 = 3(10)-1

<1 = 30-1

<1 = 29°

<1+<2 = 180 (angle on a straight line)

29+<2 = 180

<2 = 180-29

<2 = 151°

Similarly, on substituting x = 10 into <3

<3 = 2x+9

<3 = 2(10)+9

<3 = 20+9

<3 = 29°

<3+<4 = 180 (angle on a straight line)

29+<4 = 180

<4 = 180-29

<4 = 151°
