| r + 3 | > 7

r + 3 > 7       r + 3 < -7
r > 7 - 3        r < -7 - 3
r > 4             r < -10

so, r > 4 and r < -10
==========================
what percent of 60 is 12
percent formula : is/of = %/100
percent = x
is = 12
of = 60
now sub
12/60 = x/100
cross multiply
60x = 12 * 100
60x = 1200
x = 1200/60
x = 20%

Hey there, 

Lets solve this equation together , 

<span>Break down the problem into these 2 equations 
</span>
r+3\ \textgreater \ 7&#10;

-(r+3)\ \textgreater \ 7 

Solve the 1st equation: <span>r+3><span>7
</span></span>
--------------<span>Subtract </span>3<span> from both sides</span>

r\ \textgreater \ 7-3 

-------------- Simplify <span>7−3 </span><span>to </span><span>4 

</span>r\ \textgreater \ 4 

Solve the 2nd equation: <span>−(r+3)≥<span>7 
</span></span><span>
----</span><span>Simplify brackets
</span>
-r-3\ \textgreater \ 7 

---- Add 3<span> to both sides 
</span>
-r\ \textgreater \ 7+3 

 ----- Simplify <span>7+3</span> to <span>10 

</span>-r\ \textgreater \ 10 

---- Multiply both sides by <span>−1 

</span>r\ \textless \ -10  

<span>Collect all solutions 
</span>r\ \textgreater \ 4&#10; 

r\ \textless \ -10

Which of the following best describes a tectonic plate?
Delvig [45]

Answer:

B

Step-by-step explanation:  Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.

A race car is driven around a circular track at a constant speed of 180 miles per hour. If the diameter of the track is 1/2 mile
velikii [3]
F the diameter is 1/2 mile, that is 0.5 mile, then the radius is 0.25 -half of it!

the angular speed is theta/time, which means

 w=theta/time

but another formula for it is Velocity*radians

w=velocity*radians

velocity is 180 mph and radians are (revolution/2 radius), that is:

w=180*(1/2*0.25)
and if we calculate this, we have: w=114.59, which is the correct answer!

The cost CC (in dollars) of making nn watches is represented by C=15n+85C=15n+85. How many watches are made when the cost is $38
dangina [55]
\bf \stackrel{cost}{C}=15\stackrel{watches}{n}+85\qquad \boxed{C=385}\qquad \stackrel{cost}{385}=15n+85&#10;\\\\\\&#10;380=15n\implies \cfrac{380}{15}=n\implies \cfrac{76}{3}=n\implies 25\frac{1}{3}=n

so, 25 whole watches and hmmmm just the wristband of another maybe.
