Which one is question 20??
Answer:
Hi there!
If you are 15 right now, you would use the expression: 15+12=y
5 friends went to the game because 2 divided by two fifths is five.
The diagonals of a rhombus bisect each other at right angles, therefore m∠BEC=90°
9z + 45 = 90
9z = 90 - 45
9z = 45
z = 45/9
z = 5
