it is 140° Bc angle S and Z should add up to 180
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:
1/3000
Step-by-step explanation:
3 meters to centimeters:
3 × 100 = 300
= 1/10 ÷ 300
= 1/10/300
= 1/(10×300)
= 1/3000
