Answer:
$1.50
Step-by-step explanation:
Divide the 6 dollars by 4 times
$6/4 = $1.50
Step-by-step explanation:
let the unknown be x
(-12) - x = 10
(-12) - 10 = x
-22 = x
if you wanna check,
(-12) - (-22) = 10
10 = 10
64. Plug into the calulator (16)^3/2 make sure you put paraenthese around 16
Dacá 800 este 100% atunci 25% va fi 800/4 = 200 lei
deci resultá cá obiectul dupá reducere va costa 800-200 = 600 de lei

X^2 + 6x = 7
Divide 6 by 2 and square the result and add to both sides of the equation.
6/2 = 3 3^2 = 9 x^2 + 6x + 9 = 7 + 9
x^2 + 6x + 9 = 16
(x+3)^2 = 16
x+3 = +- Sqrt 16) = +-4
x = -3+4 = 1
x = -3-4 = -7
