Answer:
Her weight before was 100kg.
Step-by-step explanation:
This question can be solved using a rule of three.
Amy finds that her weight has decreased by 25%
So her weight is 100-25 = 75% = 0.75 of the original amount(what it was before).
Her current weight is 75kg.
Her previous weight was x, which is 100% = 1.
So
75 - 0.75
x - 1
Her weight before was 100kg.
0.40 as a decimal. 40% as a percent. :)

Given the table
The change in x is
The change in y is
Since for the same change in x, the change in y is different, given table represents nonlinear function.
The answer is= a(15) and b(135) and c (135)
Hello:-
this(*)is counted as multiplication
1. 4*2 + (-2+8)
=8+(6)
=14
2. (-2)*2 + 4
= -4+4
=0
3. 8*4/-2
= -32/2 (as -ve sign cannot be in denominator)
= -16
4. -2*4/8
= -8/8
= -1
5. -2*8/4
= -16/4
= -4
therefore it is a. -4
I hope it will help u !!!!!!!!!
