Answer:
32 degrees
Step-by-step explanation:
It a isosceles triangle , so what you do is 180-116 and divided that by 2
4x - 3y = -11
-7x - 8y = 6
We need to cancel out one of the variables so let's multiply the first equation by 8 and the second by 3 and aim to cancel y.
32x - 24y = -88
-21x - 24y = 18
Now we subtract,
53x = -106
x = -2
3y = 4x + 11 = 4(-2) + 11 = 3
y = 1
Answer: (x,y)=(-2,1)
Check:
4(-2) -3(1) = -8 - 3 = -11, good
-7(-2) - 8(1) = 14 - 8 = 6, good
54 3/11...
54 is ur whole number
3/11 = 0.27 with a line over the 27 because it is repeating
so ur answer would be : 54.27...with a line over the 27
Answer:
56.7
Step-by-step explanation:
6.3^2 * 9^2= 56.7
Answer: B. 12 girls
Step-by-step explanation:
Since the ratio is 4:3 we can multiply both sides by 4 to get 16 boys and the equivalent number of girls for this problem, 16:12
