Answer:
The cost for 1 necklace is $3.
Step-by-step explanation:
With the information provided, you can say that the amount spent in bracelets and necklaces is equal to the price per bracelet for the number of bracelets plus the price per necklace for the number of necklaces, which is:
c=3x+2y, where:
c is the total cost
x is the price per bracelet
y is the price per necklace
Now, you can say that c=21 and x=5 and solve for y to find the price per necklace:
21=(3*5)+2y
21=15+2y
21-15=2y
6=2y
y=6/2
y=3
According to this, the answer is that the cost for 1 necklace is $3.
Answer:
1,517
Step-by-step explanation:
360 times 4 equals 1440. 1440 + 77 is 1517.
the equation for the angles will be 180=132+2x where x is one of the smaller angles so this makes it into 48=2x or x=24 meaning that each of the smaller angles are 24
Answer:
Answers 3 ((3x4)x2) and 6 (3x(4x2)) are equal to eachother.
Step-by-step explanation:
1. 3(4+2)=18
2. 3+(4x2)=11
3. (3x4)x2=24
4. (3x4)+2=14
5. (3+4)+2=9
6. 3x(4x2)=24
3. and 6. are the only two answers that have the same outcome, therefore equaling eachother.
Answer: Probability theory would be my best guess, but I would need more information to be able to fully answer this question.
