Answer: 50 hours
Step-by-step explanation:
Sarah:
50 x 17 = 850
Joey:
50 x 15 = 750
750 + 100 = 850
Answer:
<u>Ravi</u> and <u>Courtney</u>
Step-by-step explanation:
<u>Simplifying the equations</u>
<u>Penny</u>
<u>Ravi</u>
- 2x + 3y = 3
- 3y = -2x + 3
- y = -2/3x + 3
<u>Courtney</u>
- -4x - 6y = -6
- 6y = -4x + 6
- y = -2/3x + 3
<u>Edwin</u>
- 6x + 6y = 9
- 6y = -6x + 9
- y = -x + 9
<u>Ravi</u> and <u>Courtney</u> would have infinitely many solutions because they are the same equation.
Answer:
6 projects
Step-by-step explanation:
Original ribbon length = 24 yards
After 10 yards given to sister, Mia is left with 24-10 = 14 yards of ribbon
Each project requires 2 1/4 yards of ribbon.
2 1/4 is 9/4 yards as an improper fraction (2 * 4 + 1 is the numerator and the denominator is unchanged)
We now have to figure out how many times 9/4 yards goes into 14 yards.
For this,
14 ÷ 9/4.
To do this, flip the numerator and denominator of the fraction and multiply
14 ÷ 9/4 = 14 × 4/9 = 56/9 . We ignore any remainder.
9 goes into 56 6 times with remainder of 2 (ignore remainder)
In other words the greatest number of projects = 6
