Answer:
r= -d x -t + w
Step-by-step explanation:
d= (w-r)/2 multiply by t to get dt=w-r, the subract w to get dt-w=-r. divide by negative 1 to get -dx-t+w=r (the x means to multiply)
The answer would be letter b.
Answer:
Step-by-step explanation:
Total players are 180
40% are boys
No. Of boys = 40% of 180
= 40/100 × 180
= 4 × 18
= 72 boys
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
Given m=3/5, P(3,2)
For Q(8,y)
first find the difference in x between P & Q
x=(8-3)=5
Multiply by the slope 3/5
5*3/5=3
Add to the y-coordinate of P
Q(8,2+5*3/5)=Q(8,2+3)=Q(8,5)
So the missing y-value is 5
