Answer: Weight of Charles = 177.5 pounds
Weight of dos = 22.5 pounds.
Step-by-step explanation:
Let x = Weight of Charles
y = Weight of dog.
As per given , we have the following system of linear equation :
We can write (ii) as :
Subtract equation (iii) from (i) , we get
Put this value in (1) , we get
Hence , Weight of Charles = 177.5 pounds
Weight of dos = 22.5 pounds.
Answer:
Step-by-step explanation:
1. 2x - 1 < x + 3
Subtract x and add 1 to both sides
2x - 1 - x + 1 < x + 3 - x + 1
x < 4
2. 5x - 1 > 6 - 2x
Add 1 and 2x to both sides
5x - 1 + 1 + 2x > 6 - 2x + 1 + 2x
7x > 7
Divide both sides by 7
7x/7 > 7/7
x > 1
3. x - 5 < 0
Add 5 to both sides
x-5 + 5 < 0 + 5
x < 5
Answer:
Yes the stand would make a profit, a $25 profit to be exact.
Step-by-step explanation:
the equation is 3n>100+0.50n
if the stand sells 50 then n=50 making it 3(50)>100+0.50(50).
by doing the multiplication then adding you'll get 150>125 since 3×50 is 150 ans 0.50×50 is 25 and you add the 25 to 100.
which means it'll gain $150 and spend $125 on maintaining the stand and for supplies with a $25 left over. It would make a profit
So I think I get it a little...but I don't know if my answer is right...
so 2 Nd and 5th grade made each $200, so $400 together.
kindergarten an 4th grade made ×2 2 Nd grade so 200×2=$400 each
first grades made same amount of money so $ 2800-$200-$200-$400-$400= $1600
kindergarten-$400
1st grade-$
2nd -$200
3rd grade- $
4th grade- $400
5th grade-$200
I don't see nothing about 3 rd grade
but I'd say 1 grades are 1st 2 Nd and 3rd so
maybe is just 2800-$200-$400-$400= $1800
so 1800-2nd =1600
and 1 and 3 are together 1600 so 1600÷2= 800 each
