The first step is to find the CHANGE. This is done by subtracting the two values and taking the absolute value. Next step is to find the ratio of the change to the original and multiplying by 100% to make it a percentage.
So;
a) change = Ι60 - 25Ι = 35.
ratio of change to original = 35:25,
multiplying by 100% will give 35/25 × 100% = 140%.
Hence it is a 140% INCREASE.
b) change = | 30 - 66 | = 36
the ratio is 36:66
multiplying by 100% = 36/66 × 100% = 0.545454... ×100% ≈ 54.5%
Hence it is a 54.5% DECREASE.

Substitute 5 into both the equations...
-2 (5)+7=-3
5^2+9=34
-3+34=31
hope this helpsss
Assuming 0 and 100 are included in the possible choices:
There are
multiples of 7 between 0 and 100, so there is a
probability of choosing a multiple of 7.
Answer is 5 hope i helped

➷ Congruent means it is the same shape and size. Therefore, A is incorrect as a triangle and a square aren't the same shape. The same applies to B. C is also incorrect as not all circles are the same size.
In short, the correct answer is option D. None of the above is true.
