Answer:
Step-by-step explanation:
3 times the number of yards is feet
let x represent the number of yards
Given:
Teddy has two sisters. One of them is 3 years younger than Teddy, the other one is 7 years younger than her only brother.
To find:
The age of older sister at the time when the younger sister was born.
Solution:
Let the age of Teddy be x.
One sister is 3 years younger than Teddy.
Age of one sister = x-3 years
The other one is 7 years younger than her only brother. It means other sister is 7 years younger than Teddy.
Age of other sister = x-7 years
Clearly (x-3) > (x-7). So, difference between the ages of sisters is



Therefore, the age of older sister is 4 years when the younger sister was born.
D, because if u plug it in both equation, u will get the same solution.
y=x-1
2=3-1
2=2
y=-3x+11
2=-3(3)+11
2=-9+11
2=2
Hope this helps!
Answer:
1596.2 ft/m
Step-by-step explanation:
<u>Data</u>
- height of water, h = 11 ft
- acceleration of gravity, g = 32.17 ft/s²
Given that 60 seconds are equivalent to 1 minute:
g = 32.17 ft/s² * 60² s²/1 min² = 115812 ft/min²
From Bernoulli's theorem:
velocity = √(2gh)
velocity = √(2*115812*11)
velocity = 1596.2 ft/m
Answer:
