Answer: (-2, 8)
Explanation:
Plug x = -2 into the second equation. Isolate y.
5x+3y = 14
5(-2)+3y = 14
-10+3y = 14
3y = 14+10
3y = 24
y = 24/3
y = 8
We have x = -2 lead to y = 8.
Therefore, the ordered pair (x,y) = (-2,8) is the solution to this system.
Divide by 10^6, which is .000123
Centi is 10^-3 and Kilo is 10^3 so the difference is 10^6.
3x-5y=17x+6y
-5y=14x+6y
-11y=14x
Answer:
6.85% decrease
Step-by-step explanation:
Initial Price = $3.65
Final Price = $3.40
Difference in price = Final - Initial = $3.40 - $3.65 = - $0.25
The negative sign indicates that the price decreased hence we can say that the decrease is positive $0.25.
% decrease
= (Amount decreased / initial price) x 100%
= (0.25 / 3.65) x 100%
= 6.85% decrease
for president, we have 12 possible options
12_
Once we’ve decided on a president we only have 11 possible people to choose from for vice president
12_11
multiplying these options together gives us:
12•11= 132
So the answer is C.132
