'2aa4b' is a 5 digit number and when its divided by '36' it gives '11' as remainder. What is the sum of the values 'a' can have.

Answers

Answer 1

Answer:
The only 5-digit numbers that do the job are 21,143 and 28,847 .

So, either
a = 1 and
b = 3

or
a = 8 and
b = 7 .

The sum of the values that 'a' can have is (1 + 7) = 8 .

I shall cherish every one of your generous 5 points.

Working
The nth term of an arithmetic series is calculated using the formula
nth term= a+ (n-1) d
a= -5, n =10 and nth term in this case is 13
Thus
13= -5 +(10-1)d
13= -5+9d
9d= 18
d = 2

Answer:

Step-by-step explanation:

Working

The nth term of an arithmetic series is calculated using the formula

nth term= a+ (n-1) d

a= -5, n =10 and nth term in this case is 13

Thus

13= -5 +(10-1)d

13= -5+9d

9d= 18

d = 2

Find the solution of 3 times the square root of the quantity of x plus 5 equals negative 9, and determine if it is an extraneous solution.

Answers

Answer: x= 4 is an extraneous solution.

Step-by-step explanation:

Since we have given that

$3(√(x+5))=-9$

We need to find the extraneous solution.

So, our equation becomes,

$√(x+5)=(-9)/(3)\n\n√(x+5)=-3\n\n\text{On squaring both sides}\n\nx+55=(-3)^2\n\nx+5=9\n\nx=9-5\n\nx=4$

Now, we will check that x = 4 is an extraneous solution.

$3√(4+5)\neq -9\n\n3√(9)\neq -9\n\n3* 3\neq -9\n\n9\neq -9$

Hence, x= 4 is an extraneous solution.

The solution is $x=4$ .

How do you solve 4(6x-1)=120 if you're solving for x

Answers

4(6x-1)=120
Multiply the number outside the parenthesis(4) with the numbers inside the parenthesis(6 and -1)
24x-4=120
Add 4 to both sides
24x=124
Divide both sides by 24
Final Answer: x= 5.1667 or 5 1667/10,000
