Answer:
55 lbs of $0.40 and 45 lbs of $1.40
Step-by-step explanation:
Let's say that we have two buckets, one that weighs x pounds and the candies in it are $0.40 per pound and another that weighs 100-x pounds (because we know the two added together must be 100 pounds) and the candies in it are $1.40 per pound.
There is a third bucket that is made when you combine the two, it weighs 100 pounds and the candies in it are $0.85. Multiply the cents per pound by the pounds of the candy for each bucket and you get this equation:
0.4 * x + 1.4 (100-x) = 0.85 * 100
Solve!
0.4x + 140 - 1.4x = 85
-x + 140 = 85
-x = -55
x = 55
From this we get that 100 - x = 45.
So, the answer is 55 lbs of $0.40 and 45 lbs of $1.40
Answer:
20%
Step-by-step explanation:
250*4=1000
200*4=800
1000-800=200
200 is 1/5 of 1000
1/5=20%
Paralell means has same slope
y=mx+b
m=slope
given
y=3/4x-9
sloe is 3/4
y=3/4x+b
find b
given point (-8,-18)
sub
x=-8 and y=-18
-18=3/4(-8)+b
-18=-6+b
add 6
-12=b
y=3/4x-12 is equation
