sorry if its not right
Well the increase is 132/120. Simplify by dividing 12 from the numerator and the denominator, you should get 11/10.
11/10 is also 110%
Let's call the younger student's age A and the older student's age B. The teacher's age will be T.
B = 2A
T = 5B
T+5 = 5(A+5)
Simplify the last equation.
T+5 = 5A+25
T = 5A+20
Now we have two equations solved for T, so we can set them equal to each other.
5B = 5A + 20
We can plug 2A in for B
5(2A) = 5A + 20
10A = 5A + 20
5A = 20
A = 4
To find T, we plug 4 in for A in T = 5A + 20
T = 5(4) + 20
T = 40
The answer is 40 years old.
Answer:
3000
Step-by-step explanation:
x = original amount of GHC
--> 1/6x = 500
x= 3000
Answer:
y + 9 = -0.4(x-7)
Step-by-step explanation:
in slope form , we will use y - y1 =m ( x - x1) ,
which will be y + 9 = -2/5(x-7) ,
in reduced form , we have y + 9 = -0.4(x-7)
