Answer:

y = 3

Step-by-step explanation:

The left side has to equal the right side

10 = 2y+4

Subtract 4 from each side

10-4 = 2y+4-4

6 = 2y

Divide each side by 2

6/2 = 2y/2

3 = y

Answer:

y = 3.

Step-by-step explanation:

Since we know that this is a rectangle, this means that there are two pairs of parallel and congruent sides.

If the width of the rectangle equals 10, then 2y + 4 must equal 10.

Solve for 'y':

10 = 2y + 4

6 = 2y

y = 3.

The height of a painting is 48 ronded ft. Between which two consecutive whole numbers is 48 rounded

Karolina [17]

Answer:

47 and 49

Step-by-step explanation:

This would not be between two consecutive whole numbers. Any number from 47.5 and less than 48 would round up, and any number from 48 to less than 48.5 would round down. It might be consecutive odd numbers that you meant, or your question is not clear enough.
