Answer:way to much
Step-by-step explanation:
10 xy + 3y + 20 ax + 6a = y(10x+3) + a(20x+6) = y(10x+3)+2a(10x+6)=
(y+2a)(10x+3)
Step-by-step explanation:
The formula for compound interest is
P = I (1 + r/n)^nt
where
P: the total amount of money in the account after a certain amount of time
I: the principal amount
r: the interest rate as a decimal
n: the number of times a year interest is compounded
t: the number of years passed
For Patrick:
P = 200 (1 + 0.02/12)^12*8
P = 200 (1 + 0.00166667)^96
P = 200 (1.00166667)^96
P = 200 * 1.00166667^96
P = $234.67
For Brooklyn:
P = 200 (1 + 0.04/4)^4*8
P = 200 (1 + 0.01)^32
P = 200 (1.01)^32
P = 200 * 1.01^32
P = $274.99
After 8 years, Patrick has $234.67 and Brooklyn has $274.99
$3.85 per gallon is the price per gallon
To solve for x, we will begin by using the distributive property
6x - 2(x + 4) = 12
6x - 2x - 8 = 12
(always remember to sort your negatives!)
Add like terms
4x - 8 = 12
Add 8 to both sides
4x = 20
Divide both sides by 4
x = 5
