Answer:
.5 years
Step-by-step explanation:
52 weeks = 1 year
26 weeks * 1 year/52 weeks = .5 years
2^7b = 2^5
Now you have like bases. This means that you can set the exponents equal , meaning 7b= 5. B =5\7
<span>Here the given equation is :
2-8x= -6
By bring -6 on the Left Hand size and taking 8x on the Right Hand side, the equation become.
2+6= 8X
8= 8X
X=8/8
X=1
Hence value of X is 1.
Hence correct option is A.</span>

Answer:
7
Step-by-step explanation:
We want to find the number 4-digit of positive integers n such that removing the thousands digit divides the number by 9.
__
Let the thousands digit be 'd'. Then we want to find the integer solutions to ...
n -1000d = n/9
n -n/9 = 1000d . . . . . . add 1000d -n/9
8n = 9000d . . . . . . . . multiply by 9
n = 1125d . . . . . . . . . divide by 8
The values of d that will give a suitable 4-digit value of n are 1 through 7.
When d=8, n is 9000. Removing the 9 gives 0, not 1000.
When d=9, n is 10125, not a 4-digit number.
There are 7 4-digit numbers such that removing the thousands digit gives 1/9 of the number.
