(x-7)² = 36
The square root of both is √(x-7)² =√6²
x-7 = + or - 6
x-7 = 6 , then x = 13
x-7 = -6, then x = 1
So the values of x are 13 or 1
Answer:
Multiplying and dividing fractions are essentially the same process which you multiply the numbers straight across and no need for common denominators. Except in division of fractions, the second fraction is flipped so that the denominator is on the top and the numerator is on the bottom (reciprocal).
Step-by-step explanation:
Example:
![\frac{3}{4} * \frac{1}{5} = \frac{3}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%20%2A%20%5Cfrac%7B1%7D%7B5%7D%20%3D%20%5Cfrac%7B3%7D%7B20%7D)
÷ ![\frac{1}{5} = \frac{3}{4} * \frac{5}{1} = \frac{15}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%20%3D%20%5Cfrac%7B3%7D%7B4%7D%20%2A%20%5Cfrac%7B5%7D%7B1%7D%20%3D%20%5Cfrac%7B15%7D%7B4%7D)
Answer:
$2,259.71
Step-by-step explanation:
(refer to attached)
the formula for compound interest is:
A = P [ 1 + (r/n) ] ^ (nt)
Where,
A = final amount
P = principal amount (given as $600)
r = interest rate = 7% = 0.07
n = 12 (because compounded monthly)
t = time elapsed (given as 19 years)
Substituting these into our equation,
A = P [ 1 + (r/n) ] ^ (nt)
A = 600 [ 1 + (0.07/12) ] ^ [(12)(19)]
A = 600 [ 1 + 0.005833 ] ^ 228
A = 600 [ 1.005833 ] ^ 228
A = 600 [ 3.7662 ]
A = $2,259.71
