Answer:
200 pounds 20% raisins
800 pounds 5% raisins
Step-by-step explanation:
Let number of 5% be x
and number of 20% be y
x + y = 1000
Also;
5% of x + 20-% of y = 8% of 1000 pounds
= 0.05x + 0.2y = 80
From i , x = 1000-y
0.05(1000-y) + 0.2y = 80
50-0.05y + 0.2y = 80
0.15y = 30
y = 200
x = 1000 - y
= 1000-200 = 800

Answer:
20 degrees C
Step-by-step explanation:
You would substitute the F with 68 since it is 68 degrees F. Then you would solve the equation. (Subtract 32 from 68=36; multiply 36 by 5/9=20)
-2/5 +1/2w = -6/7
move the -2/5 over by addition
1/2w = -16/35
w = -32/35
