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

The length of the third side is a-2.
Given that:
Perimeter of triangle: 6a + 3
Length of first side: 2(a+3)
Length of second side: 3a -1
Let the length of the third side of the triangle be x.
Then as perimeter of a triangle is sum of lengths of all 3 sides of the triangle, thus we have:
Thus we have length of the third side as a -2.
Answer:
2.24
Step-by-step explanation:
This problem can actually be changed from a subtraction problem to an addition problem. Two negative signs together make a positive.
So, the problem becomes:
-96.43
+ 98.67
Now, remember this phrase to help solve problems like this:
Same sides add and keep. Different signs subtract. Keep the sign of the higher number.
