Greetings!

"Solve for y:3x+1/5y=7"...

Add -1/5y to both sides.
(3x+1/5y)+(-1/5y)=(7)+(-1/5y)
Simplify.
3x=7-1/5y
Divide both sides by 3.
(3x)/3=(7-1/5y)/3
Simplify.
x=(7-1/5y)*1/3
x=7/3-1/15y

Hope this helps.

Answer:

  B.  10 units

Step-by-step explanation:

The distance formula is useful.

  d = √((3-(-5))² +(-2-4)²) = √(64 +36) = √100

  d = 10

The distance from L to M is 10 units.

Find the area of the rectangle with the given base and height.
Temka [501]

Answer: 3 1/3 ft^2

Step-by-step explanation:

Start by converting the inches into feet

1 ft = 12 in

4 in/1 x 1 ft/ 12 in = 4/12 ft = 1/3 ft

Now, imagine just multiply like normal for a rectangle:

Area of a rectangle = base x height

Area of rectangle = (10 ft) (1/3 ft)

Area of rectangle = 3 1/3 ft^2
