Answer:
a. 32
b. 48
Step-by-step explanation:
Forty percent of the 80 birds were robins.
a. How many of the birds were robins?
b. How many of the birds were not robins?
___________________
Forty percent of the 80 birds that were robins = 40%/100%
To find how many of the birds were robins, use part/whole = part/whole
40%/100% = ?/80
This will tell us how many exact robins were there
To solve, multiply 80 by 40 and then divide all by 100
80 x 40 ÷ 100 = 32
so 32 of the birds were robins
now for b since 32 of the birds were robins out of 80 birds, subtract 32 from 80.
80 - 32 = 48

Hope this helps. - M
I)
8 - 3x = 23
-3x = 15
x = -5
ii)
5x - 16 = 34
5x = 50
x = 10
iii)
2 - 5x = -3
-5x = -5
x = 1
