-2m+12
Answer:
Let c be the common factor between Jill and Kelly’s money. Then:
4n-156 / 5n-156=8/11
So:
44n-1716=40n-1248
4n=468
n=117
Jill had 4n, or $468 to begin with
Kelly had 5n, or $585 to begin with ………..
Answer:
D
Step-by-step explanation:
given A = π(R² - r²)
divide both sides by π, hence
R² - r² =
add r² to both sides
R² = + r²
Take the square root of both sides
R = → D
Answer:
ΔABC is a isosceles triangle at A
=> ∠BAC = 180 - 2.∠ABC = 180 - 2.65 = 50°
because AB//CD => x = ∠BAC = 50°
