5x + 5x +3x (like terms)
13x-60=180
180+60=240
240/13=18.4615
X=18.4615

I hope this is correct.
(There are so many different ways to do math problems like this) I hope I could help... sorry if I didn’t.

Find x so that l || m. state the converse used.
kenny6666 [7]

Answer:

x = 12

Converse: Alternate Interior Angles Converse

Step-by-step explanation:

By the Alternate Interior Angles Converse, if (14x - 23) = (9x + 37), then l || m.

Use the equation to solve for x as follows:

14x - 23 = 9x + 37

Subtract 9x from each side

14x - 23 - 9x = 9x + 37 - 9x

5x - 23 = 37

Add 23 to both sides

5x - 23 + 23 = 37 + 23

5x = 60

Divide both sides by 5

\frac{5x}{5} = \frac{60}{5}

x = 12

What are the three angle measures in the triangle shown below
sergeinik [125]
B. 31°, 43°, 106°
since all angles of a triangle add up to 180°, you combine all of the equations to equal 180 and solve for X. the equation you would get it 3x+1+11x-4+5x-7=180. this simplifies to 19x-10=180. then you solve for x, and it is 10. then, you plug 10 into all of the equations separately to find the angles. therefore, the answer is B

The maximum pounds of cheese that Ariana can buy is 8

Step-by-step explanation:

Let

x ---> the amount of cheese In pounds, that  Ariana can buy

we know that

The cost of 3 loaves of bread plus the cost of the cheese must be less than or equal to $50

so

The inequality that represent this situation is

3(3.36)+4.99x\leq 50

10.08+4.99x\leq 50

solve for x

subtract 10.08 both sides

4.99x\leq 50-10.08

4.99x\leq 39.92

divide by 4.99 both sides

x\leq 8

Therefore

The maximum pounds of cheese that Ariana can buy is 8
