10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:
{y = -2 x - 2
{16 x + 6 = -2
in the second equation, look to solve for x:
{y = -2 x - 2
{16 x + 6 = -2
subtract 6 from both sides:
{y = -2 x - 2
{16 x = -8
divide both sides by 16:
{y = -2 x - 2
{x = -1/2
substitute x = -1/2 into the first equation:
{y = -1
{x = -1/2
collect results in alphabetical order:
answer: {x = -1/2 , y = -1
Answer from: Quest
0.0076, if you meant 4.125 divided by 0.03125 it would be 132
step-by-step explanation:
first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125
then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.
now you divide like you would normally would and get 0.0076
Answer from: Quest
isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?
a^2 + b^2 = c^2
let c = distance from starting point.
(3)^2 + (5)^2 = c^2
9 + 25 = c^2
34 = c^2
sqrt{34} = sqrt{c^2}
sqrt{34} = c
Answer from: Quest
i think it would be c
