AlexFokin [52]2 years ago

Answer:

y = -2

x = 5

Step-by-step explanation:

3x - y = 17

-x + y = -7

here we can find the sum of the two equations

2x = 10

x = 5

now we can just plug in the value of x to find y

-(5) + y = -7

y = -2

rjkz [21]

Order 3/8, 3/7, and 3/9 from least to greatest without writing equivalent fractions with a common denominator explain your Strategy

3/9 3/8 3/7

The greater the denominator, the smaller the pieces are. Thus, numbers with equivalent numerators but smaller denominators will be larger than those with larger denominators.

<span>Traveled Downstream a distance of 33 Mi and then came right back. If the speed of the current was 12 mph and the total trip took 3 hours and 40 minutes.
Let S = boat speed in still water then                                                                         (s + 12) = downstream speed                                                                                  (s -12) =  upstream speed 
     Given Time = 3 hours 40 minutes = 220 minutes   = (220/60) h = (11/3) h                      Time = Distance/Speed
                  33/(s +12) + 33/(s-12) = 11/3                                                                               3{33(s-12) + 33(s +12)} = 11(s+12) (s -12)                                                          99(s -12 + s + 12) = 11(</span> s^{2} + 12 s -12 s -144)                                                   99(2 s) = 11(s^{2} -144)                                                                                        198 s/11 = (s^{2} -144)                                                                                         18 s = (s^{2} -144)                                                                                            (s^{2} - 18 s - 144) = 0                                                                                         s^{2} - 24 s + 6 s -144 =0                                                                                       s(s- 24) + 6(s -24) =0                                                                                            (s -24) (s + 6) = 0                                                                                                  s -24 = 0, s + 6 =0                                                                                                s = 24, s = -6                                                                     Answer) s = 24 mph is the average speed of the boat relative to the water.

Andy is blowing up a spherically shaped balloon. If he is able to blow 81π cm^3 of air with every breath, it takes him 12 breath
Allisa [31]

The radius of the balloon given the information in the question is 8.98cm.

<h3>What is the radius of the balloon?</h3>

The first step is to determine the volum of the balloon.

Volume = 81π cm^3 x 12 = 972π cm^3

Now, determine the radius using this formula:

∛[Volume / (4/3π )]

∛[972π cm^3/ (4/3π )] = 8.98cm

Here is the complete question:

Andy is blowing up a spherically shaped balloon. If he is able to blow 81π cm^3 of air with every breath, it takes him 12 breaths to fully inflate the balloon. What is the radius of the balloon?
