PLEASE HELP WITH THESE 4 PROBLEMS

Marizza181 [45]

Answer:

y = -5/2x + 5
y = 2x -1
y = 24/11
y = 4x + 4

Step-by-step explanation:

To solve for y, subtract the x-term and divide by the coefficient of y.

5x +2y = 10

2y = -5x +10

y = -5/2x + 5

__

2y -4x = -2

2y = 4x -2

y = 2x -1

__

7y +4y = 24

y = 24/11

We assume there is a typo, but cannot tell what it is. Use the same method as described and demonstrated for the other problems.

__

-2x +1/2y = 2

1/2y = 2x +2

y = 4x +4

The top of a circular table has a radius of 16 inches . What is the approximate circumference of the tabletop ? Use 3.14

Elena-2011 [213]

Answer:

A)100 in

Step-by-step explanation:

Given: Radius of circular table= 16 inches

Now, solving for circumference of the tabletop.

Remember, circumference of circle= $2\pi r$

we know pi= 3.14

∴ Circumference= $2\times 3.14\times 16$

⇒ Circumference of circular tabletop= 100.48 in ≅ $100\ in$

∴ Circumference of circular tabletop is 100 in.
