What value 10b when b 9?
If b = 9 then the value of 10b is 90
Find the digits of a two digit number whose sum is 7 and the number increases by nine when the digits are transposed?
The number is 34 a + b = 7 a = 7 − b 10a + b + 9 = 10b + a 10(7 − b) + b + 9 = 10b + 7 − b 70 − 10b + b + 9 = 9b + 7 72 = 18b 4 = b 3 = a
What is b plus 9b?
10b
If a number consists of two digits which add up to nine and when the digits are reversed the original number is decreased by forty five then what was the original number?
72 1) a+b=9 2) ab-ba=45==> 10a+b-(10b-a)=45==>9a-9b=45==>a-b=5 per (1) and (2) a+b+a-b=9+5 ==> 2a=14==>a=7 per (2) a-b=5==> b=2 ab=72; ba=27
What is 10a x 10b equal to?
9
What value 10b when b 9?
If b = 9 then the value of 10b is 90
How do you solve this equation 14b2-10b-36?
2(7b + 9)(b - 2)
Find the digits of a two digit number whose sum is 7 and the number increases by nine when the digits are transposed?
The number is 34 a + b = 7 a = 7 − b 10a + b + 9 = 10b + a 10(7 − b) + b + 9 = 10b + 7 − b 70 − 10b + b + 9 = 9b + 7 72 = 18b 4 = b 3 = a
What is b plus 9b?
10b
What is 3a plus 2b-4a plus b?
The given expression can be simplified to: 3b-a
A number written as the sum of the values of it's digits?
If it's a one-digit number then any 1-digit number will do (0...9) 2-digits numbers : ab=10a+b=a+b it's not possible unless a=0 For 3-digits: abc=100a+10b+c=a+b+c => 100a+10b = a+b it' not possible unless a=b=0 And so on...
10(b - 3) plus 5?
It is equivalent to: 10b-25
How can I determine all 3 digit numbers which are equal to 11 times the sum of the squares of their digits?
The primary equation is N = 100a + 10b + c for integers a, b and c. Also, 100a + 10b + c = 11m where m = a^2 + b^2 + c^2. Substitution and simplification yield 100a + 10b + c = 11a^2 + 11b^2 + 11c^2. There are two cases, where b = a + c, or b = a + c - 11. Solving these two cases results in the answer of N = 550, 803.
What is the value of b if -5 plus 10b equals -31?
-5 + 10b = -3110b = -26b = -2.6
If a number consists of two digits which add up to nine and when the digits are reversed the original number is decreased by forty five then what was the original number?
72 1) a+b=9 2) ab-ba=45==> 10a+b-(10b-a)=45==>9a-9b=45==>a-b=5 per (1) and (2) a+b+a-b=9+5 ==> 2a=14==>a=7 per (2) a-b=5==> b=2 ab=72; ba=27
How do you slove 10b equals 11?
The equation 10b = 11 can be solved for b by dividing both sides of the equation by 10. b = 11/10 or 1.1
What is the gcf of 30 ab and 50 b?
10b
