Answer:
- Third choice: {3, 4, 6, 7, 9}
Explanation:
Please, find the Venn diagram attached.
You have to find the set that represents the union of the set M and N (M ∪ N). That is a set with the elements that belong either to set M or set N.
The elements that belong to the set M are the numbers inside the circle M: 3, 4, 7 and 9.
The elements that belong to the set N are the numbers inside the circle N: 4, 6 and 7.
The complete list of the numbers in the union set is 3, 4, 6, 7, and 9, as you must not repeat the elements that belong to both sets.
So, the set that represents M ∪ N is the third option {3, 4, 6, 7, 9}.
12.5 yds at 4.50 per yd : 12.5 * 4.50 = 56.25....what she paid for the fabric
she uses 2.5 yds of fabric for each dog bed.....12.5 / 2.5 = 5...so she can make 5 dog beds
each dog bed sells for 17.50.....5 * 17.50 = 87.50
87.50 (what she earned from selling the dog beds) - 56.25 (the cost of the fabric) = 31.25......so her total profit is $ 31.25 <==
Answer:
x = 3
Step-by-step explanation:
4 ( x - 7 ) = -6x + 12
→ Expand brackets
4x - 28 = -6x + 12
→ Add 6x to both sides
10x - 28 = 12
→ Add 28 to both sides
10x = 30
→ Divide both sides by 10
x = 3
X+y=24 so we can say
x=24-y making 3x+5y=100 become
3(24-y)+5y=100
72-3y+5y=100
72+2y=100
2y=28
y=14, since x=24-y
x=10
So there are 10 3-point questions and 14 5-point questions.
