Answer:
3
Step-by-step explanation:
You can solve for any variable. From the first equation, let's solve for c :
Now, replace the value of c into the other equation:
Using distributive property
However, keep in mind that this is true for:
Answer:
0
Step-by-step explanation:
any thing that is multiplied by 0 will be 0
(x , y) = (7, - 1)
2x + 3y = 11 → (1)
3x + 3y = 18 → (2)
subtracting (1) from (2) term by term eliminates the y- term
(3x - 2x) + (3y - 3y) = (18 - 11)
x + 0 = 7 ⇒ x = 7
substitute x = 7 into either of the 2 equations and solve for y
(1) → (2 × 7) + 3y = 11
14 + 3y = 11
subtract 14 from both sides
3y = 11 - 14 = - 3
divide both sides by 3
= - 1
solution is (7 , -1)
The time at which the break started is 10 : 30 am.
<h3>What time did the break start?</h3>
The first step is to convert the time between 10:00 a.m. - 11:15 a.m. to minutes.
The time between 10:00 a.m. - 11:15 a.m. is 1 hour 15 minutes
In order to convert hours to minutes, multiply hour by 60
1 x 60 = 60 minutes
60 minutes + 15 minutes = 75 minutes
The second step is to subtract the time from the break from the duration of the golf lesson
75 minutes - 15 minutes = 60 minutes
The third step is to divide 60 minutes into equal halves by dividing 60 by 2
60 / 2 = 30 minutes
The last step is to add 30 minutes to the time the lesson started : 10 : 00 am + 30 minutes = 10 : 30 am

Answer:
6pi
Step-by-step explanation:
you would do 180-120 to get 60 degrees that will be your theta. then devide 36 by 2 to get your radian. then pi/3 (beacuae 60 degrees is equal to pi/3) multplied by 18 and you get 6pi
