X: earn per  hour during the week
y: earn per hour during the weekend

13x + 14y = 250.90
15x + 8y = 204.70

Multiply the first equation by 4 and the second equation by 7

52x + 56y = 1003.6
105x + 56y = 1432.90

Subtract the first equation from the second:

 53x = 429.30

x = 429.30/ 53
x = 8.10

Solve any of the equation for y:

15x + 8y = 204.70

y = [204.70 - 15(8.10)]/8 = 10.40

y - x = 10.40 -8.10 = 2.30

Answer: she earns $2.30 per hour more during the weekend than during the week.

kylie bought a bunch of grapes that weighs 2 pounds and 9 ounces. How much did the grapes weigh in ounces only?
Grace [21]
Since 1 pound is 16 ounces, you would convert the 2 pounds to 32 ounces (16+16) and add the 32 ounces to the already given 9 ounces to get 41 ounces. (32+9)
Hope that helped.

Viktor [21]

Answer:

\frac{3}{4}

Step-by-step explanation:

Total number of the students in the pep squad = 12 students

The number of the students wearing white shirts = 3 students

The number of the students wearing blue shirts = 6 students

Either white or blue shirts indicate that the students wearing white shirt or blue shirt.

Thus, number of students wearing either white or a blue shirt = 3 + 6 students = 9 students

So,

The fraction is:- \frac{9}{12}=\frac{3}{4}
