I need to solve for y Plz help!

Mathematics
1 answer:
Allushta [10]3 years ago
3 0

Start with

5x+8y = 6\pi

Subtract 5x from both sides:

8y = 6\pi-5x

Divide both sides by 8:

y = \dfrac{6\pi-5x}{8}

This is the expression solved for y, because we wrote an equivalent expression with y alone on the left hand side, and an expression not involving y on the right hand side

Two angles of a triangle have a sum of 110. the sum of all three angles is 180 .what is the measure of the third angle
defon
Well by the looks of it The missing angle is 70 degrees. I say this because 110 + 70 = 180. If you were asking what were the two angles just divide.

Tickets to a local circus cost $5 for students and $8 for adults. A group of 9 people spent a total of $60. How many adults were
S_A_V [24]

Answer:

5

Step-by-step explanation:

You need to set up and solve a system of linear equations here.

Let s and a represent the number of students and adults respectively.

Then s + a = 9, and s = 9 - a.

Total ticket cost for the adults was ($8/adult)(a)

and for the students ($5/student)(s).

Total cost of the tickets was then  ($8/adult)(a) + ($5/student)(s) = $60.

Then our system of linear equations is:

8a + 5s = 60

 a  +  s  = 9, or s = 9 - a.  Substituting 9 - a for s, we get:

8a + 5(9 - a) = 60.

Then 8a + 45 - 5a = 60, or 3a = 15.

Solving for a, we get a = 5.

Solving for s using s = 9 - a, we get   s = 9 - 5, or s = 4.

There were 5 adults in the group (and 4 students).
