Third angle = 180 - (6x+7) - (10x-3)
= 180 - 6x - 7 - 10x + 3
= 176 - 16x
just minus the sum of triangle by the 2 angles and you're left with the 3rd one

Answer:

equation of the table is y=30x+60

60 degrees is what the temperature starts at

to get to 440 degrees he needs 12 minutes and 40 seconds

Step-by-step explanation:

the change in y over change in x is 90/3 which is the slope

slope is 30

if slope is 30 then 30*2+b=120 60+b=120 so b=60 and it is the y intercept

440=30x+60

380=30x

x=12 2/3

x= 12 minutes and 40 seconds

Styline menswear ordered short-sleeve shirts for $23 each and long-sleeve shirts for $28.50

short-sleeve shirts for $23

long-sleeve shirts for $28.50

Total cost = $9,862.50

Let x be the number of short - sleeve

and y be the number of long  - sleeve

Total shirts = 375

x + y = 375

23x + 28.50y = 9862.50

Now we solve for x  

x + y = 375 ( subtract x on both sides)

So y = 375 - x

Now plug in 375 -x for y in second equation

23x + 28.50y = 9862.50

23x + 28.50(375 - x ) = 9862.50

23x + 10687.5 - 28.50x = 9862.50

subtract 10687.5  from both sides

23x  - 28.50x = -825

-5.5x = -825 (divide -5.5 on both sides)

x = 150

So number of short-sleeve = 150

5x+14&lt;4 or -2(x-8)&lt;-2
Kitty [74]

Answer:

Step-by-step explanation:

5x+14<4 or -2(x-8)<-2

    -14 -14      -2x+16<-2

5x<-10                -16  -16

÷5  ÷5           -2x<-18

x<-2              ÷-2   ÷-2

                     x>9   (sign changes because you divide by a negative number)

x<-2 or x>9

Captain Jessica has a ship, the H.M.S. Khan. The ship is two furlongs from the dread pirate Luis and his merciless band of thiev
erik [133]

Answer: Probability that both the pirate and the Captain hit each other's ships is \frac{1}{9}

Step-by-step explanation:

since we have given that

Probability that the captain hits the pirate ship is given by

\frac{4}{9}

Probability that the pirate hits the Captains's ship is given by

\frac{1}{4}

So, we have to find the "Probability that both the pirate and the Captain hit each other's ship"  is given by

P(\text{Captain hits})\times P(\text{ Pirates hit})\\\\=\frac{4}{9}\times \frac{1}{4}\\\\=\frac{1}{9}

Hence, probability that both the pirate and the Captain hit each other's ships is \frac{1}{9}
