Mean of wat? And we need to see a picture of the equation
Answer:
1. 9/24 = 0.375 ounces
You have 9 ounces of clay that make up 24 pieces therefore you need to divide the 9 by 24 to work out how much clay is used for one piece
2. X=7
To solve the equation you want x to be on its own. To do this you need to minus the 5 from the left. But what you do to one side you must do to the other so x=7 because 12-5=7
3. 3y-1
To get three times yvonnes age you need to multiple y by 3 making it 3y. You then need to take off one year which quite simply makes the expression 3y-1
4. 18/3= 6mm
You divide the total depth by the number of hours to get 6mm.
5. 3x3=9 yards
6 skirts is three times as many skirts as 2 skirts (6/2=3) and because Laura uses 3 yards for every 2 skirts you multiple 3 by 3 to get the 9 yards
Hope this helps :)
Step-by-step explanation:
Ans 6 Use Pythagoras theorem...
Hypotneuse²=Base²+Height²
6²=4²+H²
36-16=H²
20=H²
√20=H
√2×2×5=H
2√5 = H....
hope it helps
