Answer:
19
Step-by-step explanation:
58/3 = 19.333333
19×3 = 57
so one shirt would be removed so all three boxes have 19 shirts in each box
Answer:
9 blue balloons
Step-by-step explanation:
Let's create a proportion using the following set up.
blue balloons/total balloons=blue balloons/total balloons
We know that 10 blue balloons were sold if 20 total balloons were sold. We don't know how many blue are are sold if 18 total are sold. Therefore, we can say x blue are sold for 18 total sold.
10 blue/20 total=x blue/18 total
10/20=x/18
We want to find out what x is. In order to do this, we have to get x by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
x is being divided by 18. The opposite of division is multiplication. Multiply both sides by 18.
18*(10/20)=(x/18)*18
18*(10/20)=x
18*1/2=x
9=x
If 18 balloons are sold, 9 blue balloons would be expected to be sold.
It's the smallest value in this equation which should at x=-10, the equation is x=-b/(2a)
A triangle always adds up to 180 degrees total. Therefore the triangle is 70 + 26 + C = 180. Solving for C you would get 84 degrees.
F(x) = 2w + I = 2w 5000/w
f'(x) = 2 - 5000 / w^2
Fencing is minimum, so f(x) = 0
2 - 5000/w^2 = 0
2 = 5000 /w^2
2w^2 = 5000
w = 50
I = 5000/2
= 1000
2w + I
= 200
hope this helps
