R + b = 21
2b = r
now we sub eq 2 into eq 1
r + b = 21
2b + b = 21
3b = 21
b = 21/3
b = 7
2b = r
2(7) = r
14 = r
so there are 7 bluejays (b) and 14 robins (r)...for a total of 21
something through 1-10. i think its 7 but i rlly dont know. Sry.

Answer:
(4c-d+0.2)² - 10c = 33
___________________
Step-by-step explanation:
(4c-d+0.2)^2-10c
c=3.1, d=4.6
(4(3.1) - 4.6 + 0.2)² - 10(3.1) = (12.4 - 4.6 + 0.2)² - 31 = (7.8 + 0.2)² -31 = 8² - 31 = 64-31 =33.
