Help me solve those show work 3(2a-5)=12-7a, 27=3c-3(6-2c)and 6c-8-2c=-16
posledela
3(2a-5) = 12-7a
6a-15=12-7a
6a+7a=12+15
13a= 27

27=3c-3(6-2c)
27=3c-18+6c
27+18=3c+6c
45=9c
C=45/9
C=5

6c-8-2c=-16
6c-2c=-16+8
4c=-8
C=-8/4

Find a of this angle.
Mice21 [21]

In a triangle, the total angle is 180 degrees. A straight line is always 180 degrees. With this in mind, the following can be obtained:

a + 2x + {57}^{o}   =  {180}^{o}  \\ 5x + a =  {180}^{o}

These are simultaneous equations.

a + 2x +  {57}^{o}  = 5x + a \\ 3x =  {57}^{o}  \\ x =  {19}^{o}  \\ 5x + a =  {180}^{o} \\ 5( {19}^{o}  ) + a =  {180}^{o}  \\ a =  {85}^{o}

ariana grande is coming to north gulfport middle school for a fundraising benefit concert!Nevaeh is selling tickets.This week,sh
ArbitrLikvidat [17]

Answer:

Adult = $7

Kids = $4

Step-by-step explanation:

Before we can find the price of the tickets, we first need to create expressions that can be used to explain the prices.

Let x = Price of kids tickets

Let y = Price of adults tickets

For this week the expression is:

3x + 9y = 75

For the last week the expression is:

8x + 5y = 67

Now to be able to find the value of x or y, we can use the Solving Linear Equations by Multiplying First Method.

3x + 9y = 75

8x + 5y = 67

Now we need to remove either the x or y by multiplying the whole expressions by a certain number.

8(3x + 9y = 75)

24x + 72y = 600

3(8x + 5y = 67)

24x + 15y = 201

Now that we have our equations and we can eliminate the x by subtracting both expressions.

24x + 72y = 600

<u>- 24x + 15y = 201</u>

         57y = 399

To find the value of y, we divide both sides by 57.

\dfrac{57y}{57}=\dfrac{399}{57}

y = 7

Now that we have the value for y, we simply substitute the value in any of our expressions.

3x + 9y = 75

3x + 9(7) = 75

3x + 63 = 75

3x = 75 - 63

3x = 12

Now we divide both sides by 3 to find the value of x.

\dfrac{3x}{3}=\dfrac{12}{3}

x = 4

So the ticket prices are:

Adult = $7

Kids = $4
