What is the value of x in 2.5(6x-4)=10+(1.5+0.5)
Alecsey [184]

Answer:

x = 22/15

Step-by-step explanation:

2.5(6x-4)=10+(1.5+0.5)

Combine like terms

2.5(6x-4)=10+(2)

2.5(6x-4)=12

Divide each side by 2.5

6x-4 = 4.8

Add 4 to each side

6x = 8.8

Divide by 6

6x/6 = 8.8/6

x = 88/60

x = 22/15

If the diameter of a circle is 19.3, what is the circumference?
vlabodo [156]

Answer:

60.6

Step-by-step explanation:

The formula for finding the circumference of a circle is C = 2πr

C is circumference, π is pi (we'll just us 3.14 here), and r is radius.

The radius is found by dividing the diameter in half.

19.3/2=9.65

So the equation should look like this:

C = 2(3.14)(9.65)

C = 60.602

C = 60.6

Can someone help me with this :/
slavikrds [6]

Answer:

2x² + x - 1 = 0

a= 2 b= 1 c= -1

x = [ -b +- sqr rt( b^2 -4ac) ] / 2*a

x = -1 +- sqr rt (1 - 4 *2*-1) / 4

x1 = [ -1 + (sqr rt (1 +8)) / 4

x1 = ( -1 + sqr rt (9)) / 4

x1 = (-1 + 3) / 4

x1 = .5

x2 = (-1 -3) / 4

x2 = -4 / 4

x2 = -1

50,000+4,000+20+5 in expanded form
Deffense [45]

Answer:

It’s already in expanded form.

Step-by-step explanation:

The original number is 54,025.

Expanded form is when you kind of “take apart” a number. You basically break it apart.

Example: Write 24,382 in expanded form.

Correct way: 20,000 + 4,000 + 300 + 80 + 2

Incorrect way: 2 + 4 + 3 + 8 + 2 (that would equal 19, which is way off from 24,382).

I hope this helps, let me know if you have any questions!
