Answer:

Yes, x=1 is the solution

Step-by-step explanation:

You would divide both sides of the equation by 2, that leaves you with x+13=14

Next you would move your constant, which in this case is 13, so x=14-13

Then you would subtract the numbers by each other so 14-13 equals one which makes x=1

Answer:

2,322,775

Step-by-step explanation:

$a_1=4\\\\a_i=a_{i-1}+11\\\\\implies a_2=a_{2-1}+11\\a_2= a_1+11 \\a_2= 4+11 \\a_2= 15\\\\d = a_2-a_1 \\d= 15-4 \\d= 11\\\\S_{650}=?\\\\\implies n = 650\\\\$

By the formula of sum of an Arithmetic Sequence

$S_n= \frac{n}{2} [2a_1+(n-1)d]\\\\S_{650}= \frac{650}{2} [2\times 4+(650-1)\times 11]\\\\S_{650}= 325 [8+649\times 11]\\\\S_{650}= 325 [8+7,139]\\\\S_{650}= 325\times 7,147\\\\\huge \red {\boxed {S_{650}=2,322,775}}$

Answer: $22,063.2

Step-by-step explanation:

quarterly means that 4 times per year this interest, the balance can be find by the equation:

A = P*(1 + r/4)^(4*t)

Where P is the initial value, r is the rate of increase (7.3% in this case, but remember that you must use the decimal form; 0.073) and t is the number of years:

so we have:

B = $6,000*( (1 + 0.073/4)^(4*18) = $22,063.2
