If 3x−y=12, what is the value of 8x/2y?

Mathematics
1 answer:
patriot [66]3 years ago
4 0

Answer:

17.2

Step-by-step explanation:

3x=12+y

x=12+y/3

8(  \frac{12 + y}{3}) \div 2y

\frac{96 + 8y}{3} \times  \frac{1}{2y}

\frac{96 + 8y}{6y}

(y is divided by y so it no longer exists)

\frac{96 + 8}{6}

\frac{104}{6}

I) Construct a triangle PQR such that |PQ|=8cm,{RPQ=90°{PQR=30°.Measure |RQ|​
scoray [572]

Answer:

6.93 cm

Step-by-step explanation:

You have a right triangle (90°), so you do as follow:

If I understand correctly, you are looking for the hypotenuse so

cos(30) = \frac{PQ}{QR} = \frac{8 cm}{QR}

That is equal to QR = cos(30)*8 cm = 6.928 cm

What is the value of the equation -2/3x + 9 = 4/3 x -3?​
MArishka [77]

Answer:

x = 6

Step-by-step explanation:

\frac{-2}{3}x+9=\frac{4}{3}x-3\\\\\frac{-2}{3}x-\frac{4}{3}=-3-9\\\\\frac{-2-4}{3}x= - 12\\\\\frac{-6}{3}x = -12\\\\ -2x  -12\\\\x = \frac{-12}{-2}\\\\x = 6

One angle of a triangle is 50 degrees greater than the smallest​ angle, and the third angle is 10 degrees less than twice the sm
tia_tia [17]
All 3 angles of a triangle must equal to 180. You can simply set up an equation to solve this and set it equal to 180.

Angle 1 - 50 + x
Angle 2 - x
Angle 3 - 2x -10

50+x+x+2x-10=180
4x+40=180
4x=140
x=35

Angle 1 = 50+35= 85
Angle 2 = 35
Angle 3 = 2(35) - 10 = 60

60+35+85=180
