5 0
Set it up as a ratio to find what 40% of 250 mL is:
 x            40
---      =   ------
250       100
Then it becomes (40*250)/100, which is 100.
Finally, add 100 to 250. Your answer is 350.

On a number line, A is at -2 and B is at 4. What is the coordinate of C, which is 2/3
STatiana [176]

Answer:

  2

Step-by-step explanation:

The distances have the ratio:

  (C -A) = (2/3)(B -A)

  C = (2/3)B +(1/3)A . . . . . add A

  C = (2B +A)/3 . . . . . . . . combine terms

  C = (2(4) +(-2))/3 = 6/3 = 2

The coordinate of C is 2.

Quadrilateral ABCD is inscribed in the circle. Which sentence is true?
astra-53 [7]

Answer:

A) A and B are supplementary

Step-by-step explanation:

we know that

For any inscribed  quadrilateral in the circle , opposite angles will be supplementary

so

In this problem

Angle A and Angle B are supplementary angles

m\angle A+m\angle C=180^o

Angle B and Angle D are supplementary angles

m\angle B+m\angle D=180^o

therefore

<u><em>The sentences that are true </em></u>

A) A and B are supplementary

Answer and shown work for 5x + y = 10 -x - y = -2
konstantin123 [22]
Solve first equation for y: 
5x+y=10
y=10-5x. Plug this equation into second equation

-x-(10-5x)=-2
-x-10+5x=-2
4x=8
x=2 (plug x into first equation)

5(2)+y=10
y=0
