Answer: 78 problems
Step-by-step explanation:
Let x = the total number of problems that Joe started with. Joe finished half of his homework questions at school. This means that he finished 1/2 × x = x/2 of the home work at school. What he has left is x - x/2 = x/2.
He completed one-third after practice. This means he completed 1/3 × x = x/3 after practice The number of problems left altogether would be total number of problems - the the sum of the amount he finished at school and the amount he completed after practice. It would be x -(x/2 + x /3) = x - 5x/6 = x/6
If he has 13 to more to finish, that means
x/6 = 13
x = 13×6 = 78 minutes

2/3 of a basket of apples rot. We eat 4/5 of the rest and use the remaining 25 to make jam. How many apples were in the basket
Answer:
375
Step-by-step explanation:
Since the basket was full, ⅔ rot so the remaining for any use will be 1-⅔=⅓
Since we only eat 4/5 of this remaining quantity, we use the 1-4/5=1/5 of ⅓ for making jam
1/5 of ⅓=1/5*⅓=1/15
If 1/15 equals 25 pieces then the full basket had
25*15/1=375 pieces
Answer:
25%
Step-by-step explanation:
3/12 = 1/4 = 0.25 = 25%
Answer:
x = negative 1 plus-or-minus StartRoot 17 EndRoot
Step-by-step explanation:
Given:
We need to solve for x.
First we will solve L.H.S
Factorizing the equation we get;
Now Things which are equal to the same thing are also equal to one another. Since
then, according to the law of transitivity,
Now, applying the Square Root Principle we get:
Now Square root and square gets cancelled.
Since a square root has two values, one positive and the other negative.
Hence Final Answer is .
The sweater has a discount with is 40% of the regular price.
She saved 20 dollars on the sweater that she bought.
Let's solve for the original price of the sweater then,
=> 20 dollars = 40%.
Let's look for the 60%.
=> 20 / 4 = 5 dollars is the 10% of the sweater's original price.
=> 5 dollars * 10 = 50 dollars
=> Thus the original price of the sweater is 50 dollars.
