-2x3 (5+3-83x3) then just put that in a calculator or do it in your head
3y^-4/3 x 2 3/y
Write in exponential form with the base of y
= 3y^-4/3 x 2y^1/3
Calculate the product
= 6y^-1
Any expression raised to the power of equals its reciprocal
= 6 x 1/y
Calculate the product
= 6/y
Answer:
(C) Annie did not make a mistake
Step-by-step explanation:
To isolate the variable k in the equation 
, we'd have to subtract 7.5 from both sides so we just had k on one side.
This is exactly what Annie did, and therefore, her answer is correct.
Hope this helped!
Answer:
the correct answer is option C
Answer:
Area= 840
Step-by-step explanation:
Area= (20x13)x2+(10x12x1/2)x2+10x20
=520+120+200
=840
- Area=Two area of the triangle [13x20] + Two area of the rectangle + Under area (rectangle)- [10x20]
