A. 2/5 because of you take 3/4 and roughly cut it in half, it would be 3/8 which is close to 2/5, but a little less since in the problem, you aren't completely cutting 15 people in half to get 8, so it is an estimate
Answer:
x= -8 , y = 5
x= 25/4 , y = 1/4
Step-by-step explanation:
substitute first eqn into the second eqn:
(7 - 3y)^2 -y^2 = 39
49 - 42y + 9y^2 - y^2 = 39
8y^2 - 42y +10 =0
4y^2 - 21y + 5 = 0
(4y-1) (y-5) = 0
y= 1/4 , 5
when y=1/4
x = 7- 3/4
=25/4
when y= 5
x = 7- 15
= -8
Answer:
Step-by-step explanation:
3(x - 2) = -27
3x - 6 = -27
3x = -21
x = -7

Answer:
Step-by-step explanation:
In order to get the answer to this question you must change the mixed number into a improper fraction then multiply the improper fraction as many times as it's exponent.
Turn the mixed number into a improper fraction:
Now multiply:
Turn the improper fraction into a mixed number:
