Answer:

x = 5

AB = 13

BC = 17

Step-by-step explanation:

So we have to make an equation;

(2x + 3) + (4x - 3) = 30

Collect like terms

6x = 30

Divide both sides by 6

x = 5

To find AB we have to plug in the value of x;

2x + 3 = 2(5) + 3

10 + 3 = 13

AB = 13

To find BC we also have to plug in the value of x;

4x - 3 = 4(5) - 3

20 - 3 = 17

BC = 17

Step-by-step explanation:

because you do

2x+3 = 4x+3

-3              -3

2x=4x

-2x -2x

x = 2

2x2+3

4+3

=7

4x2-3

The type of equation given below is in point-slope form <br> y=1/2x-5 true or false
kykrilka [37]

Answer:

false

Step-by-step explanation:

point slope form : y - y1 = m( x - x1 )

the equation y = 1/2x - 5 does not follow this therefore the answer is false

the equation y = -1/2x - 5 is instead put in slope intercept form , y = mx + b

At the theater, the Garcia family bought 2 adult tickets and 3 children's tickets for $44.50. The Smith family bought 3 adult ti
kondaur [170]

Answer:

Adult= $11

Children = $7.5

Step-by-step explanation:

Let x represent adult ticket and y represent children ticket

2x + 3y= 44.50........equation 1

3x + 6y= 78........equation 2

From equation 1

2x + 3y= 44.50

2x= 44.50-3y

x= 44.50-3y/2

Substitute 44.50-3y/2 for x in equation 2

3x+ 6y= 78

3(44.50-3y/2) + 6y= 78

66.75- 4.5y +6y= 78

66.75 + 1.5y= 78

1.5y= 78-66.75

1.5y= 11.25

y= 11.25/1.5

y = 7.5

Substitute 7.5 for y in equation 1

2x + 3y = 44.50

2x + 3(7.5)= 44.50

2x + 22.5= 44.50

2x = 44.50-22.5

2x= 22

x= 22/2

x= 11

Hence the price of adult ticket is $11 and the price of children ticket is $7.5
