Answer:
Step-by-step explanation:
4.5b + 8.5c = 175
b + c = 22.......b = 22 - c
4.5(22 - c) + 8.5c = 175
99 - 4.5c + 8.5c = 175
-4.5c + 8.5c = 175 - 99
4c = 76
c = 76/4
c = 19......there are 19 cats
b + c = 22
b + 19 = 22
b = 22 - 19
b = 3 <==== there are 3 birds
S = 3/5 or 0.6
explanation
-4/0.8 = 2/s-1
divide the numbers on the left: -5 = 2/s-1
multiply both side by s-1: -5(s-1)=2
simplify: -5s + 5 =2
gather like terms: -5s= 2 - 5
simplify: -5s= -3
divide both sides by -5: x=3/5
Answer:
4
Step-by-step explanation:
30÷100=0.3
0.3×80=24
28-24=4
Answer:
2x4-6
Step-by-step explanation:
2x4 is 8, and 8-6=2. Therefore 2x4-6=2
dy%2Fdx+=+6x%5E2 So the slope at x = 2 is 6*(2^2) = 24
