Answer:
Step-by-step explanation:
hello :
An = 10 -10/2^n
the first 4 terms are :
A1 = 10 -10/2^1 = 10-5
A1 = 5
A2 = 10 -10/2^2 = 10-10/4 = 10-5/2 = (20-5)/2
A2 = 15/2
A3 = 10 -10/2^3 = 10-10/8 =10- 5/4 = (40-5)/4
A3 = 35/4
A4 = 10 -10/2^4 = 10-10/16 = 10-5/8 = (80-5)/8
A4 = 75/8
An integer is a whole number and the product of numbers means to multiply them. So so we know that:
x * y = x - 50
So the product (x * y) is 50 less than one of the integers ( x - 50)
I can divide both sides by x:
y = (x - 50) / x where x is not zero
y = x/x - 50/x
y = 1 - 50/ x
x can no longer be zero since you cannot divide by zero
the only way for y to be a whole number is if 50/x is a whole number. 50/x can onky be a whole number if x is a factor of 50. so take any factor of 50 and that will be possible answers.
factors of 50: 1,2,5,10,25,50
these would be possible x values. To to find corresponding y values plug in x
y = 1 - 50/1
y = 1 - 50
y = -49
So first pair is (1, -49)
do the same for the rest and get
(2, -24)
(5, -9)
(10, -4)
(25, -1)
(50, 0)

PEMDAS parentheses equation multiplication division adding subtraction
The 7 is 10 times bigger in 26475 than the 7 in 503497. why? because the 7 in 26475 is in the 10's place and the 7 in 503497 is in the ones place.
If you need clarification on the 10 times bigger part...consider this whats 1×10? 10
. If the 7 was in the 100 place and the other 7 was in the 10 place then it would be 10×10=100 and so on
