Answer:
25
Step-by-step explanation:
Each of the 16 "ratio units" representing all 80 dancers must stand for ...
(80 dancers)/(16) = 5 dancers
Then 5 "ratio units" representing seventh-grade dancers will stand for ...
5 × 5 dancers = 25 dancers
___
Another way to figure this is to write the proportion ...
(seventh-grade dancers)/(all dancers) = 5/16
seventh-grade dancers = (all dancers)×(5/16) = 80×5/16
seventh-grade dancers = 25

Answer:
6*4(4+2) - 4*-1^2 = 140
Step-by-step explanation:
Answer:
7x - 3y = -34
7x - 3(2) = -34
7x - 6 = -34
7x - 6 + 6 = -34 + 6
7x = -28
7x/7 = -28/7
x = -4
7(-4) - 3y = -34
-28 - 3y = -34
-28 + 28 - 3y = -34 + 28
-3y = -6
-3y/-3 = -6/-3
y = 2
(-4, 2)
