Answer:

r2=48

Step-by-step explanation:

r1=72

s1=12

s2=8

r \alpha s \\  \frac{r1}{s1}  =  \frac{r2}{s2}  \\  \frac{72}{12}  =  \frac{r2}{8}  \\ r2 = 8 \times \frac{72}{12}  = 48

In quadrant 2 , x is ? and y is ?
Bezzdna [24]
In quadrant 2, x is negative which means x < 0. Also, in quadrant 2, y is positive so y > 0.

An example point that is located in quadrant 2 is the point (-5, 8). Note how the first coordinate is -5 so x = -5 which is negative. Furthermore, the second coordinate is 8 meaning that y = 8 which is positive. 

Quadrant 2 is the quadrant on the upper left-hand side of the four quadrants on the xy coordinate system.

Jeremiah is traveling 70 mph. If Jeremiah keeps driving that speed, how far will Jeremiah be
Mazyrski [523]

This means in 5 hours, Jeremiah can travel up to 350 miles.

Plzzz helppp!!<br> 9-4x=17????
AnnyKZ [126]

Answer:

<h3>\boxed{ \bold{ \boxed{ \sf{x =  - 2}}}}</h3>

Step-by-step explanation:

\sf{9 - 4x = 17}

Move 9 to right hand side and change it's sign

⇒\sf{ - 4x = 17 - 9}

Subtract 9 from 17

⇒\sf{ - 4x = 8}

Divide both sides of the equation by -4

⇒\sf{ \frac{ - 4x}{ - 4}  =  \frac{8}{ - 4}}

Calculate

⇒\sf{x =  - 2}

Hope I helped!

Best regards!!
