It is 5% active, so if we have 10 gallons, the active ingredients would be 5% of 10.
5% of 10
= 0.05 * 10 = 0.5
0.5 gallons.
Answer:
Agreed
Step-by-step explanation:
-(-7y + 12) = 7y - 12
u are distributing the -sign through the parenthesis...so u take the number outside of the parenthesis (and if it just a sign, the number is 1)...and u multiply it by everything in the parenthesis.
-1(-7y + 12) = -1 * -7y + (-1) * 12 = 7y + (-12) = 7y - 12
Answer:
(2,2) is not a solution of the system.
Step-by-step explanation:
Given : Equations
and
.
To find : Is (2,2) a solution of the system?
Solution :
To know that the given point is the solution or not we have to put the values in equation if inequality is true then the point is the solution.
Substitute (2,2) in
,
![5(2)-9(2)\geq 8](https://tex.z-dn.net/?f=5%282%29-9%282%29%5Cgeq%208)
![10-18\geq 8](https://tex.z-dn.net/?f=10-18%5Cgeq%208)
![-8\geq 8](https://tex.z-dn.net/?f=-8%5Cgeq%208)
It is not true.
Substitute (2,2) in
,
![7(2)-4(2)](https://tex.z-dn.net/?f=7%282%29-4%282%29%3C10)
![14-8](https://tex.z-dn.net/?f=14-8%3C10)
![6](https://tex.z-dn.net/?f=6%3C10)
It is true.
So, (2,2) is not a solution of the system.
Answer:
15 3/10 years
Step-by-step explanation:
Ballio age = 12 4/5
Bill's age = Ballio's age + 1 1/6
Bills age = 12 4/5 + 1 1/6 = 64/5 + 7/6 = (384 + 35) / 30 = 419 / 30 = 13 29/30
Jane's age :
13 29/30 + 1 1/3
419 / 30 + 4 /3 = (419 + 40) / 30 = 459 / 30 = 15 9/30
15 9/30 = 15 3/10 years
