Hello! To solve this problem, we have to do 6 / 3/4 (6/0.75). You do this, because you’re using 6 yards of fabric and you use 3/4 yards of fabric per pillow. If you know it, use the rule Keep, Change, Flip. Keep 6/1 the same. Change the division symbol into a multiplication symbol. Flip 3/4 over into 4/3. 6/1 * 4/3 = 24/3 or 8 when simplified. Penny can make 8 pillows using 6 yards of fabric.
Answer:
30 and 18
Step-by-step explanation:
The equations representing a "sum and difference" problem are easily solved using elimination or substitution.
<h3>Setup</h3>
Let 'a' and 'b' represent the two numbers.
a + b = 48 . . . . . the sum
a - b = 12 . . . . . . the difference
<h3>Solution</h3>
Add the two equations to eliminate 'b'.
2a = 60
a = 30 . . . . . . . divide by 2
b = 30 -12 = 18
The two numbers are 30 and 18.

<em>Additional comment</em>
You may have noticed that the larger of the two numbers is half the sum of the given numbers: a = (48+12)/2 = 30. Similarly, the smaller of the two numbers is half their difference: (48-12)/2 = 18.
This is the generic solution to a "sum and difference" problem, meaning you can often work it mentally and just write down the answer.
B. 47 degrees
Explanation:
They already cut 43 degrees and they want to cut until a right angle is form which is 90 degrees. To find how much more they have to cut, do 90-43 which gives you 47.
