Answer:
10 girls are not on either team
Step-by-step explanation:
first subtract 6 from 8 to get 2 (since it's easier) because those 6 girls are on the math league team as well
next add 2 and 13 to get 15
last subtract 15 from 25 to get 10
Answer:
2x - y - 7 = 0
Step-by-step explanation:
Since the slope of parallel line are same.
So, we can easily use formula,
y - y₁ = m ( x ₋ x₁)
where, (x₁, y₁) = (8, 9)
and m is a slope of line passing through (x₁, y₁).
and since the slope of parallel lines are same, so here we use slope of parallel line for calculation.
and, Slope = m = 
here, (xₐ, yₐ) = (2, 7)
and, 
⇒ m = 
⇒ m = 2
Putting all values above formula. We get,
y - 9 = 2 ( x ₋ 8)
⇒ y - 9 = 2x - 16
⇒ 2x - y - 7 = 0
which is required equation.
Answer:
Step-by-step explanation:
The sides are 11 each because the square root of 121 is 11. So, the permeter is 11 + 11 + 11 + 11 = 44 inches.
Hope this helped!
