The ratio birds : animals = 13 : 2
so for every 1 animal, 6.5 birds were born
last month: animals = birds - 44
birds - animals = 44
use trial and improvement to find:
if there were 52 birds, there must be 8 animals
CHECK: 52 - 8 = 44
Step-by-step explanation:
-5x - 20 +21 > - 3 +4x - 32
-5x +1 > 4x - 35
-5x +4x > - 35 +5
-1x>-30
Divide by - 1
x >30
Am I right??
The quotient of a number t and 7, plus 2, is -4 ?
t/7 +2 = -4
The answer is 7/16 of the original pizza
Well, if 'y' has zeros at x=6 and x=-8,
then 'y' must be the product
y = (x - 6) (x + 8)
Perform the multiplication to get the quadratic function:
y = x² + 2x - 48
