I believe its A ...................That question is such a drag -.-
Let x=aunt's agethen x-14=Mrs West's ageso we have:60-(x-14)=x-40 simplify60-x+14=x-40 subtract x from each side and also subtract 60 and 14 from each side60-60-x-x+14-14=x-x-40-60-14 collect like terms
-2x=-114x=57------------aunt's agex-14=57-14= 43----------Mrs West's ageck60-43=57-4017=17
Answer:
There all 67 degrees
Step-by-step explanation:
Answer:
6. C
7. F
Step-by-step explanation:
6.Using pythagoras theorem, half of side of square=24
Side of square= 2*24=48
Perimeter= 4*48= 192in.
7.Base angles of both triangles are 51 and 90.
So, triangles are similar by AA similarity theorem.
x/7= 24/15
After solving,
x= 11.2
Take original price and multiply by .75. (An item that has been discounted 25% is 75% of the original price.) the number you get will be the sale price.
