Answer:
p = 17 and -15
Step-by-step explanation:
If q is directly proportional to (p-1)², this can be written as;
q = k(p-1)²
If q = 20 when p = 3
20 = k(3-1)²
20 = 2²k
20 = 4k
k = 5
To get p wen q = 80
80 = 5(p-1)²
16 = (p-1)²
p-1 = ±√16
p-1 = 16 and p-1 = -16
p = 17 and p=-16+1
p = 17 and -15
3x - 2y = -17 -> 9x - 6y = -51
3y - 4x = 24 -> 6y - 8x = 48
9x - 6y = -51
6y - 8x = 48
------------------- +
x = -3
3x - 2y = -17
3(-3) - 2y = -17
-9 - 2y = -17
-2y = -8
y = 4

Answer:
1) Equal to 17.4
2)Less than 17.4
Step-by-step explanation:
One thing we must always remember that when we have number 0 after the decimal point, it means we do not need to consider that as it will have no effect on product and on the other operations.
So,
1)
17.4 x 1.0 = 17.4 x 1 = 17.4 (Product is equal to 17.4)
2)
Suppose if a number 'A' which is less than 1 is multiplied by any other number 'B', than the multiplication always result in the number less than B.
For example:
1x0.5 = 0.5 which is less than 1
Similarly for
17.4 x 0.98 = Result will be less than 17.4 as the second number is less than 1.
Product is less than 17.4
Answer: 0.25 and 25%
Step-by-step explanation:
2/8 is equal to 1/4. 1/4 is the same as 0.25. Move decimal point two spots to the right and BOOM you get 25%.
