Hello,
This problem can be simply solved by putting everything into fractions. Since there's a total of 50 shirts but 35 of them are medium sized then the fraction would be 35/50. You're trying to find the percentage so the 2nd fraction would be out of 100 so it would be ?/100.
35 ?
---- = ----
50 100
Now you diagonal multiplication then downwards division.
100 x 35=3500
3500/50=70
So your answer is 70%!! :D
Hope this helps a bunch!!!
Answer:
50
Step-by-step explanation:
Using the experimental probability, first we have to find total amount paint then to find the amount of good quality forever paint we have to subtract the amounts of other paints from total amount.
Let x represents the amount of good quality forever paint sold.
Total amount of paint ...(i)
Experimental probability of paint sold will be better quality durable paint is
It is given that experimental probability of paint sold will be better quality durable paint is
...(ii)
From (i) and (ii), we get
Therefore, 50 gallons good quality forever paint is sold.
For chemistry you would need to get an 84.
For Spanish you would need to get an 82.
Best of luck
Answer:
first number is 4
second number is 0
Step-by-step explanation:
y = 1st number
x = 2nd number
system of equations:
5y + 4x = 20
4y + 2x = 16
I multiplied the second equation by -2 to eliminate the 'x-values'
-2(4y + 2x = 16) = -8y - 4x = -32
now add to 1st equation: <u>5y + 4x = 20</u>
-3y = -12
y = 4
solve for 'x':
5(4) + 4x = 20
20 + 4x = 20
4x = 0
x = 0
