im confused?
Step-by-step explanation:
could you please rewrite this question? what are the numbers for?
(2*40%+x*10<span>0%)/(2+x) = 70%; calculate x !</span>
Well threw my calculations would be <span><span> x= 0.0000 - 2.0000 i
</span><span> x= 0.0000 + 2.0000 i

Answer:
2 cats were cared for
Step-by-step explanation:
c= cats
d=dogs
c+d =7
1.5c+3.5d=20.50
c+d =7
solve for d
d = 7-c
substitute into 1.5c+3.5d=20.50
1.5 c + 3.5 (7-c) = 20.50
distribute
1.5c +24.5 -3.5 c = 20.5
combine like terms
24.5 -2c =20.5
subtract 24.5 from each side
-2c = -4
divide by -2
c =2
